A total of 13 working dives were made (with biologists present as observers on three of them). Information on the bottom fauna was collected from the following sources (in order of importance): 1) direct observations from the submersible by biologists; 2) sample collection with manipulators; 3) careful analysis of all photographs and video recordings; 4) visual inspection and collection of epifauna with geological specimens; 5) debriefing of geologist observers. Numerous specific recommendations regarding the planning and conduct of observations, collection of biological specimens, keeping of dive logs, primary processing of results, processing of photographs and video recordings, and reporting on dives were developed [Anon.].

Species Composition and Distribution of Epigonus (Epigonidae) in the World Ocean. Journal of Ichthyology 32(5): 94-108. 1992 Abstract: According to the revision of Mayer, the mesobenthic-pelagic genus Epigonus consists of 12 species. Subsequent studies increased the number of species to 25 (a key for identification is provided). The genus is divided into 4 species groups: oligolepis (3 species), telescopus (4), denticulatus (9), and robustus (9). Members of this genus are widely distributed over continental slopes, island dropoffs, and underwater rises in every ocean (from Iceland in the Atlantic to 55 degree S in the Pacific Ocean) at depths ranging from 120-1400 m. Within the genus, there are both widely distributed species (E. telescopus, E. denticulatus, E. macrops, and others), and local endemics with restricted ranges (E. fragilis, E. crassicaudus, E. elegans, etc.). The genus Epigonus is one of five genera in the family Epigonidae and is typically found on continental slopes, seamounts, and rises in the world ocean. Epigonus is a mesobenthic-pelagic fish, living mainly above the bottom and rarely entering deep water, although the larvae and young of many species undertake a pelagic form of life. Some species are of commercial value or may have a fishery potential. (DBO) | English abstract Absalao, R.S. and E.D.C. Rios.

The new species is diagnosed by 5 or 6 strong spiral cords on the body whorl which show almost linear rows of very small pits on their upper surfaces. Caelatura barcellosi, new species, is found in oceanic island and seamounts from Northeastern Brazil. It is diagnosed by straight whorls, the presence of umbilicus, and 14-18 refractive axial ribs and sub and suprasutural cords forming blunt nodules at their intersections Acharyya, S.K. and T.C. Lahiri. Cretaceous Paleogeography of the Indian Subcontinent: A Review. Cretaceous Research 12(1): 3-26. 1991 Abstract: Break-up of the Greater Indian continent influenced the Cretaceous palaeogeography of the Indian subcontinent. A new set of linear fluvial to shallow marine basins was formed prior to, but mainly during the Aptian with the extrusion of basalts close to some basins, and extensively in east and northeast India. A similar basin opened along the present southern margin of the Himalayas. A mid-Cretaceous transgression in central India came from the west, whereas the Cauvery Basin in south India and the Shillong shelf in northeast India, were connected and opened eastward. The East Coast shelf and Shillong shelf were better developed during Campanian-Maastrichtian time. Extensive basaltic extrusion during the late Maastrichtian in western India was coequal with regional regression, but marine sedimentation was unbroken from the Campanian to the Palaeocene on the Shillong shelf. The Tethyan ocean-floor flanking the Himalayan shelf and the northest margin of the Indian craton was destroyed beneath Eurasia. Its Indus-Tsangpo arm was consumed during Gampanian-Maastrichtian time, whereas northern parts of the Indo-Burmese ocean contained seamounts during the Maastrichtian and Palaeocene Ackermand, D.

Piper, and H.B.S. Cooke. Late Quaternary Stratigraphy and Paleo-Oceanography of the Grand Banks Continental Margin, Eastern Canada. Boreas 12(4): 253-261. 1983 Abstract: Quaternary sediments cored on the continental slope off the Grand Banks and on nearby seamounts and abyssal hills have been correlated back to at least isotopic stage 6, using lithologic and biostratigraphic markers and warm-cold cyclicity in microfossil assemblages. The sequence is dated using limited oxygen isotope and super(14)C data. The oldest continental slope cores penetrate to a glacial stade with an extrapolated age of 50,000 B.P. The oldest seamount cores probably penetrate to isotopic stage 13. Watermass distribution over the area results from interaction of the Labrador Current with locally generated shelf water, and to a lesser extent, the Gulf Stream. Planktic foraminiferal assemblages and sedimentological evidence suggest that Arctic Labrador Current core water extends onto the eastern Grand Banks only during full interglacials Albuquerque, M.N. and A.

Pacific Science 48(4): 410-445. 1994 Abstract: Thirty-three species of caridean decapods have been identified from samples taken from the guyots and their vicinity, a little-sampled region of the mid-Pacific Ocean. Considering the oligotrophic character of the environment, a remarkably diverse collection has been collected. For the most part the species are mesopelagic and bathypelagic and have a widespread, if not cosmopolitan, distribution. Nevertheless, for many species these records extend their distribution much farther north and east in the Pacific than was previously known. The few epibenthic species present are more circumscribed in their distribution. Two of these were found to be previously undescribed and are described here Allison, E.C., J.W. Durham, and L.W.

These captures represent the first record of the genus from the eastern Pacific Ocean. The species is similar to C. crumenalis (from the Hawaiian Islands) and C. prognatha (near the Maldive Islands, Okinawa Trough, and Suruga Bay, Japan) in having a very large mouth with a well-defined gular pouch. The three species can be separated by a combination of meristic (dorsal- and anal-fin rays, vertebrae, and lateral-line scales) and morphometric characters (length of lower jaw and depth of caudal peduncle) Ameziane-Cominardi, N., J.P.

List of Fishes Collected at the Continental Shelf Limits Vitoria, Trinidade and Martin Vaz Seamounts During the MD-55 Brazil Oceanographic Campaign. Revista Brasileira de Zoologia 12(3): 579-594. 1995 Abstract: The result of an agreement between Universidade Santa Ursula, Rio de Janeiro and the Museum of Natural History of Paris, was the oceanographic campaign MD-55 Brasil which took place between May 6th and June 2nd of 1987, aboard the R/V "Marion Dufresne" of the Terres Australes et Antartique Francaises (TAAF). Samples were collected between latitudes 23 degree 36'40"S and 18 degree 49'S. Ichthyofauna sampled was relatively low, and comprised of just one family of Chondrichthyes (three species) and 50 families of Osteichthyes (104 species). Zenion hololepsis (Goode & Bean, 1895) (Zeniodontidae) is recorded for the first time from the western South Atlantic, as well as is extended the geographic limits for Myrophis frio Jordan & Davis, 1892 (Ophichthidae) and Prionotus nudigula Ginsburg, 1950 (Triglidae). Even though relatively not very representative, the species collected from the seamount chain Vitoria/Trindade and Martin Vaz suggest being identical to those which occur along the Brazilian continental platform Andrew, T.G., T.

Ichthyological Bulletin of the J.L.B.Smith Institute of Ichthyology 0(63): 1-43. 1995 Abstract: Recent collections of fishes from the South Atlantic islands of the Tristan da Cunha Group (Tristan, Inaccessible and Nightingale) and Gough Island have produced 25 new records. Fifty one species are known to occur in the near-shore waters of the islands (46 of these are documented by specimens and another 5 species are probable). A diagnosis, synonymy and in most cases, an illustration, are provided for each species. For certain species, brief notes on biology, relative abundance and seasonal distribution are included. The neritic ichthyofauna of the Subtropical Convergence (STC) region is characterized and the importance of this frontal zone as a barrier to dispersal of species in the Southern Ocean is evaluated. Analysis of the zoogeographic affinities of the Tristan/Gough fish fauna resulted in a redefinition of the West Wind Drift Islands Province (WWDI), comprising the Tristan Group and Gough in the South Atlantic and St. Paul and Amsterdam Islands in the southern Indian Ocean. Vema Seamount (west of Cape Town) and Walters Shoal (south of Madagascar) are excluded from the WWDI Province, as the affinities of their poorly-known fish faunas appear to be more with South Africa and the tropical Indian Ocean respectively Andriyashev, A.P.

Marine Ecology Progress Series(186): 265-269. 1999 Abstract: Five hormone-treated female Japanese silver eels Anguilla japonica were tagged with ultrasonic transmitters and released by submersible in the West Pacific at seamounts of the West Mariana Ridge, their supposed spawning grounds. Four eels were tracked for 60 to 423 min in the vicinity of the seamounts. They did not settle at the seamounts but swam at a mean speed of 0.37 m s-1 into open water above deep ground. Their mean swimming depth ranged from 81 to 172 m. Experiments suggest that pre-matured A. japonica migrate to their spawning grounds in temperate warm water and at shallow depths Aydin, K. Abiotic and Biotic Factors Influencing Food Habits of Pacific Salmon in the Gulf of Alaska. Tech.Rep.North Pac.Anadr.Fish Comm: 39-40. 1998 Abstract: A major difficulty in assessing feeding competition, and thus quantifying density-dependent growth and the carrying capacity of Pacific salmon (Oncorhynchus spp.) in the North Pacific Ocean, arises from the large amount of variability in high-seas foraging conditions, both within and between years. Differences in prey populations, prey patchiness, seawater temperature, and other oceanographic conditions all conspire to mask the relationship between salmon density and food. Salmon density as measured by catch per unit effort does not represent uniform competition, as salmon may differ in their food preferences depending on species, size, age, or maturity condition. This study analyzed food habits of salmon collected along a 145 degree W transect line, between 50 degree and 56 degree N, in July 1994-97. Data was examined over oceanic seamounts at 143-147 degree W, 55-57 degree N, in the 1980s and 1990s. Using generalized additive models, generalized linear models, and graphical analysis of stomach content data, the contribution was shown of some biotic and abiotic factors in the feeding variability of pink (Oncorhynchus gorbuscha), chum (O. keta) sockeye (O. nerka) and coho (O. kisutch) salmon. Results reveal the interplay between sea surface temperature, oceanographic conditions, salmon size and maturity, catch rates, and interannual changes in salmon prey. (D.B.O.) Backus, R.H. and L.V.

Brittle Stars (Ophiuroidea) in the Northeast Atlantic, in the Ibero-Moroccan-Mauretanian Region: Comparison of the Faunas With Taxonomic Remarks. Spixiana 14(1): 95-112. 1991 Abstract: When comparing the ophiuroid fauna collected on the seamounts Great Meteor Bank and Josephine-Bank with that from the shelf and upper continental slope off Portugal and northwestern Africa, the most obvious fact is the paucity of the seamount fauna. The dominant taxa on the seamounts are the amphiurids (Great Meteor Bank) and ophiodermatids (Josephine-Bank); both taxa are microphagous. The fauna off portugal and northwestern Africa is more diverse; beside microphagous deposit and suspension feeders macrophagous scavengers (carrion, plant fragments) and plankovores are common. The ophiuroid communities along the lower continental slope are rich in species. Of all samples studied, the highest faunal diversity was found in one from the Ibero-Moroccan Bay, taken at 1750 m depth Basov, I.A. Stratigraphic and Biogeographic Patterns of Paleogene Planktic Foraminifers in the Subarctic Pacific. Abstracts of Papers Presented at the 30Th International Geological Congress 2: 243. 1996 Abstract: Deep-sea drilling at ODP Sites 883 and 884 on the Obruchev Rise provided the first continuously cored Paleogene section in the subarctic Pacific containing planktic foraminifers. Foraminifers are persistent throughout the Paleogene section at shallower Site 883 and they occur only sporadically at deeper Site 884. The uppermost Paleocene, lower Eocene, middle Eocene, and upper Eocene lower Oligocene intervals are defined based on planktic foraminifer assemblages, which are mostly composed of acarininids and subbotinids. A composition of the assemblages and species morphology as well as their general low diversity and abundances indicate temperate to cold-water habitat. They resemble the coeval assemblages from both the northern and southern high-latitude areas: Falkland Plateau, Maud Rise, Kerguelen Plateau, New Zealand, Campbell Plateau, Crimea-Caucasus, and northern Kamchatka. Despite the general impoverishment of the planktic foraminifer assemblages in the subarctic Pacific, because of both the high-latitude position of this area during the Paleogene and strong dissolution, changes in their diversity and composition through the section reflect global climatic fluctuations that had been established by a number of studies worldwide. The comparison of Paleogene planktic foraminifers from different North Pacific, both higher- and lower-latitude, sections shows that the assemblages at Obruchev Rise sites take the intermediate position between those from northern Kamchatka and Shatsky and Hess rises, respectively. The impoverished Paleogene assemblages from the former area (60 degree N) are thought to belong to the temperate-boreal province (Krasheninnikov, Serova, and Basov, 1988). In the latter area (32-35 degree N), planktic foraminifers are much more diverse and include along with acarininids and subbotinids various thermophilic forms that are characteristic of the southernmost part of northern subtropical belt. The upper Paleocene assemblage at northern DSDP Site 443, the Suiko Seamount (45 degree N) also shows subtropical features. This places the Paleogene assemblages of planktic foraminifers from the Obruchev Rise in the northern subtropical province, which is supported by paleolatitude estimates (Kono, 1974; Rea.

Predominant over Walters Seamount were the larvae of mesopelagic oceanic fishes, the fry of deepwater benthopelagic species were not numerous and the larvae of shallow-water fishes occurred only as single specimens. Over the seamount summit the taxonomic composition of ichthyoplankton was poorer and the biomass and abundance were lower. An appreciable proportion of samples from Saya de Malha bank was accounted for by the larvae of shallow-water species while the larvae of deepwater benthopelagic fishes were rare. The taxonomic composition of ichthyoplankton over the bank was more diverse, and the abundance and biomass were much higher than over Walters Seamount Belyanina, T.N. An Investigation of the Ichthyoplankton on Seamounts in the Western Indian Ocean. Journal of Ichthyology 33(2): 17-25. 1992 Abstract: In pelagic waters above the Walters Seamount and Saya de Malha Bank, 35 ichthyoplankton samples were collected. In addition, above the Saya de Malha Bank, several epibenthic samples were also taken. Larval mesopelagic oceanic fish were exceedingly predominant above the Walters Seamount. Juveniles of deep-water benthopelagic species were rarely found. The larvae of shallow-water fishes were encountered only individually. Above the seamount peak, an impoverishment of species diversity and some reduction in biomass and abundance of ichthyoplankton were noted. Over the Saya de Malha Bank, a significant portion of the catch consisted of larval shallow-water fish in addition to larval mesopelagic fish; larvae of deep-water benthopelagic fish were rare. The taxonomic composition of the ichthyoplankton over the banks was more varied, its numbers and biomass-slightly higher than those over the Walters Seamount. (DBO) Belyanina, T.P.

The high values were confined to a satellite eddy which is a migrating warm anomaly. Bottom elevations were found to induce eddy generation and to produce a considerable effect on inhomogeneity of water bioproductivity which resulted in the formation of high concentrations of live fractions of microplankton Bernard, F.R.

Cowen. Temporal Variations in the Deep-Water Colonization Rates of Small Benthic Foraminifera: The Results of an Experiment on Cross Seamount. Deep-Sea Research Part I: Oceanographic Research Papers 46(6): 1021-1049. 1999 Abstract: Modern benthic foraminifera are important remineralizers of organic matter and a link between surface-ocean production and life in the deep sea. Assemblages of benthic foraminifera are preserved in the fossil record, providing clues to paleoceanographic conditions. These clues can be fully interpreted only when our knowledge of the biology and ecology of modern species is more complete. To study factors influencing foraminiferal colonization rates, artificial substrates were placed on Cross Seamount (18degree40'N, 158degree17'W) for 1 to 42 months between 1989 and 1994. The colonization rates of benthic foraminifera onto different substrates (five mineral types were used) at four water depths (800, 975, 1285 and 2000 m) were determined. Both calcareous and agglutinated foraminifera inhabited these artificial substrates at different rates. Many of the agglutinated forms colonized at a uniform rate through time. The colonization rates of other foraminifera, primarily calcareous forms, were not constant through time, nor could the variability be attributed to the controlled variables (water depth and substrate composition). Instead, these temporal variations in colonization rate corresponded with shifts in surface ocean conditions and export fluxes in the central Pacific.

Pelagic Biogeography of the Armorhead, Pseudopentaceros Wheeleri, and Recruitment to Isolated Seamounts in the North Pacific Ocean. U S National Marine Fisheries Service Fishery Bulletin 86(3): 453-466. 1988 Abstract: The pelagic armorhead, Pseudopentaceros wheeleri, occurs widely in the North Pacific Ocean. Benthic specimens have been taken from Japan, the Hawaiian Archipelago, and the west coast of North America, but the main reproductive populations are located on southern Emperor-northern Hawaiian Ridge seamounts between lat. 29.degree. and 35.degree. N. The period between spawning and recruitment to the seamounts is apparently between 1.5 and 2.5 years, suggesting an extended pelagic existence. We describe the distributional patterns in the North Pacific based upon over 30 years of published and unpublished records. The majority of pelagic specimens are captured in the subarctic water mass in the northeast Pacific. Based upon the distributional patterns and the oceanography of the North Pacific, we propose migratory paths for both the main population and for the individuals that occur rarely in other locations. The long pelagic period and variability in ocean conditions may play an important role in recruitment to seamounts and the variability in year-class strength for this species Boehlert, G.W.

Bulletin of Marine Science 53(2): 336-361. 1993 Abstract: Seamounts and oceanic islands support demersal or neritic fish populations and are localized sources of eggs and larvae added to a background of oceanic ichthyoplankton. Associated larval fish assemblages, however, have been identified in few studies, and most have been based on subjective classifications of species by reproductive characteristics. At seamounts, little evidence exists that ichthyoplankton assemblages differ from the background field despite physical mechanisms proposed to maintain planktonic forms. Larvae of bottom-associated species are notably rare in samples taken in these regions. In contrast, characteristic ichthyoplankton assemblages have been described at oceanic islands. Unique assemblages may exist in embayments and lagoons, but they are not well described. Nearshore assemblages (0 to 0.5 km offshore) are dominated by larvae of small species with demersal eggs; neritic assemblages (0.5 to 5 km offshore) include inshore species with demersal and planktonic eggs mixed with larvae of certain species that are usually oceanic as adults. Although larvae of some inshore species with pelagic eggs are found offshore in oceanic assemblages (beyond 3 to 5 km), assemblages there are poorly described. Spatial and seasonal spawning behavior of adults plays the key role in formation of ichthyoplankton assemblages. Mechanisms that may maintain ichthyoplankton assemblages at islands include boundary layers, small scale frontal dynamics, tidal currents, topographically produced eddies, seasonally reduced or variable currents, and regions of no or returning flow. Behavior of larvae, particularly that affecting vertical distribution, can modify the influences of these mechanisms. The integrity of assemblages can be disrupted by both biotic and abiotic factors Boehlert, G.W. Productivity and Population Maintenance of Seamounts Resources and Future Research Directions.

Pacific Science 48(1): 57-69. 1994 Abstract: The lightfish, Maurolicus muelleri (Gmelin), is a cosmopolitan sternoptychid fish most abundant near continental shelf-slope breaks and rare in the open ocean. Recent studies have documented dense populations on seamounts of the South Atlantic and North Pacific. At Southeast Hancock Seamount, a small guyot in the central North Pacific, M. muelleri populations are mainly composed of juveniles. Seasonal length frequencies suggest that recruitment at sizes greater than 20 mm standard length (SL) occurs principally in spring and summer months, with growth over summer and fall coincident with decreasing abundances. Mature fish in reproductive condition occur in winter months but do not survive to the following spring; they also may be too few at this small seamount to support annual recruitment. Potential sources of additional recruitment include populations at several larger seamounts in the southern Emperor group and also the large populations around Japan. Advection of eggs and larvae in the Kuroshio Extension may provide recruits for dependent populations at the seamounts. Mean current flow and satellite-tracked drifters suggest a transit time of 100-200 days from the coast of Japan to the region of the seamounts; estimates of age at length suggest that smaller fish have similar ages at recruitment. Gill-raker counts, however, differ between Japanese and seamount populations. We suggest that the southern Emperor Seamount populations serve as the source for replenished annual recruitment to the small population at Southeast Hancock Seamount Boldyrev, V.Z., V.B.

Various factors affecting bioproduction in such zones are described to include high nutrient inflow which is caused mainly by circulation of water. Physical and seasonal aspects of water dynamics are reviewed in detail using numerous scientific sources. Ocean is regarded to be a system of eddies. Closed eddy zones are characterized by specific levels of nutrient accumulating capacity and serve as fish concentration areas.

[Biologicheskie Resursy Talassobatial'Noj Zony Mirovogo Okeana.], A.S.Grechina [ed.], Sb.Nauchn.Tr., Vniro, pp. 231-245. 1991 Abstract: The ichthyofauna of the Lord Howe Ridge seamounts is represented by species of tropical and subtropical complexes. The distribution of fish and the variability of the species composition on different banks and guyots is determined by association of different species with particular water masses differing in abiotic and feeding conditions and separated horizontally by frontal zones and vertically by high gradient hydrological divides. The fish of the tropical complex associated with the surface water mass over the Lord Howe Ridge are confined to the surface thermocline (50-150 m) and those belonging to the subtropical complex are associated with the subtropical water mass and are distributed down to the main pycnocline (400-450 m) which separates this water mass from the cold intermediate layer. The vertical distribution of the fish is also associated with the differentiation of water layers rich or poor in plankton. Higher plankton and fish biomass is usually observed in intermediate layers Boldyrev, V.Z. and V.B. Darnitskij. Distribution of fish over seamounts in the Eltanin Fracture Zone.

Epi- and Mesopelagic Fishes, Acoustic Data, and SST Images Collected Off Lanzarote, Fuerteventura and Gran Canaria, Canary Islands, During Cruise 'La Bocaina 04-97'. Ciencias marinas(5): 1-45. 1999 Abstract: During cruise 'La Bocaina 0497' a series of 14 tows with a commercial pelagic trawl at depths between 20 and 700 m and an acoustic survey with a SIMRAD EK-500 echosounder were carried out in neritic and adjacent oceanic waters off Lanzarote, Fuerteventura, and Gran Canaria, Canary Islands. In addition, SST images were obtained to get some information on the prevailing hydrological conditions in the study area. Of the 14 trawl tows, 10 were successful and resulted in capture of a total of 2166 fishes belonging to 81 species, 53 genera and 28 families. Ten species proved to be new records for the area of the Canary Islands. The acoustic survey covered a total of 2404 nm super(2) and allowed to obtain estimates of the abundance and biomass of fishes. Both the fishing results and the acoustic study revealed considerable spatial variability in biomass of chub mackerel Scomber japonicus, an epipelagic species of particular commercial fishery interest, showing clear variations in the numerical dominance of certain age- or size classes among different collecting localities. Furthermore, some juveniles in the first year of life occurred in the oceanic epipelagic during night-time together with vertically migrating mesopelagic fishes. Preliminary analyses of the stomach and intestinal content suggest that these juveniles fed close to the bottom during the day before and hence may undertake diurnal horizontal migrations between the shelf and adjacent oceanic waters. It is concluded that the great spatial flexibility of this species requires further monitoring surveys at regular intervals as a basis for establishing a sustainable fisheries management. The acoustic data together with the trawling results demonstrate the existence of a dense deep scattering layer at depths between 400 and 700 m which is composed of mesopelagic fishes and invertebrates. Clear indications of diurnal vertical migrations were found in several species with formation of a shallow scattering layer in less than 150 m depth during night. Together with typical mesopelagic species, such as stomiids and myctophids, juveniles of three benthopelagic species, which typically undergo a pelagic stage during early life, were also collected. Several individuals of mesopelagic species were collected above the shelf what may reflect the ecological boundary situation at ocean rims typical for oceanic islands and seamounts. Some mesopelagic species collected in this study may be closely associated with distinct hydrological conditions such as the myctophid Ceratoscopelus maderensis which was discovered in the SE of Fuerteventura in an area of possible local upwelling. This finding points to the existence of micro-zoogeographic zones within the Canary Islands which deserve further investigation using a small-scaled comparative approach Borets, L.A.

Revista de investigación y desarrollo pesquero 13: 0-136. 2000 Abstract: Fourteen marine zoogeographic provinces and two subprovinces were established for the Americas. The number of species of marine decapod crustaceans recorded in the supralittoral, intertidal, eulittoral and sublittoral (continental shelf to 200-300 m) including both, continental coasts from the Arctic Polar region in the north to Cabo de Hornos in the south is estimated at 2, 472 species. The results of this study on the biodiversity and distribution of decapod species call attention to a common characteristic of typical epifaunal groups of organisms with a large range of latitudinal geographic distribution: a high number of species in tropical regions on both coasts and a pronounced decrease of taxa towards the polar regions that generates a clear clinal distribution. The Caribbean Province showed the largest diversity which, with a total of 1, 058 species was higher than that of the tropical Panamic Province where 825 species were registered. With regards to the species richness in the nine major groups of Decapods, the largest number was found in the Brachyura covering 1, 090 estimated species followed by the Caridea with 536 species, the Anomura with 509 species, the Thalassinidea with 157 and the Penaeoidea with 96. The remaining four decapod taxa are represented only by a small number of species. Boschma, H. List of the Described Species of the Order Stylasteridae.

Annual Reproductive Cycle of Oocytes and Embryos of Yellowtail Rockfish Sebastes Flavidus (Family Scorpaenidae). U S National Marine Fisheries Service Fishery Bulletin 90(2): 231-242. 1992 Abstract: Female yellowtail rockfish Sebastes flavidus, a viviparous species employing intralumenal gestation following fertilization of ovulated eggs, were caught from Cordell Bank (seamount 20 miles west of Pt. Reyes, central California) on a monthly basis from May 1985 through April 1986 to determine their annual reproductive cycle. Since histological methods provide precise and detailed information, this method was employed to (1) examine oocytes and embryos to describe developmental stages, and (2) provide temporal assessment of the annual reproductive cycle. The description and staging scheme developed provide a basis to compare reproductive developmental patterns between cycles and populations. Oogonia (stage I) and early perinucleolus (Stage II) oocytes were present in samples from all months. Progressive growth of oocytes from early- to late perinucleolus (Stage III) was evident in spent and recovering ovaries, indicating the end of a reproductive year and the beginning of a new reproductive cycle. Initial yolk accumulation (Stage IV) occurred in July, and final yolk accumulation (Stage V) was predominant from September through January. In February, the majority of samples displayed fertilized ova in early-celled stages of embryonic development. Gestation continued for about 30 days with parturition occurring between January and March. Mature oocytes were also collected in March, suggesting the Cordell Bank yellowtail population has a prolonged reproductive season extending into April Bradbury, M.G.

Two new species of polynoids from the Central Pacific (Vityaz and Guyot Seamounts) are described. Polynoe uschakovi sp.n. is associated with Callogorgia sp. and Allopora sp. It occurs under the sclerites of the polyps of the former and in tubular "galls", monstrous hollow expansions of the coral walls of the latter. Harmathoe melanicornis sp.n. is associated with another species of the genus Allopora and occurs in the tubular "galls", similar to those described for P. uschakovi . In both cases the formation of galls is likely to be induced by commensals. A bibliography on polychaetes is provided Brousse, R.

Deep-Sea Research Part A: Oceanographic Research Papers 34(11): 1795-1810. 1987 Abstract: The nearly ubiquitous deep-sea amphipod, Eurythenes gryllus (Lichtenstein), occurs throughout the central North Pacific basin, and has recently been collected from the crests of three bathyal seamounts. Questions of the dispersal capabilities of the species are interesting in the light of this broad geographic and ecological distribution. We use population genetic techniques to describe the genetic structure and estimate migration rates of E. gryllus from allozymic frequencies in basin and seamount samples. Four basin samples were collected along a 4000 km transect from off the coast of California into the central North Pacific basin; two additional samples were collected at the base and on the crest of Horizon Guyot, a bathyal seamount 1300 km west off Hawaii. Allozymic variability at 15 enzyme loci was assayed by starch-gel electrophoresis, and allozymic frequency differences were evaluated statistically. Except for two comparisons (both involving the station with smallest sample size), the basin transect samples were not significantly genetically heterogeneous (mean F sub(ST) = 0.052 plus or minus 0.18 and mean Nm = 5.0 plus or minus 1.6), suggesting that individuals have excellent dispersal capabilities and/or that selection pressures do not differ over these large distances in the deep sea. In contrast, the sample from the crest of Horizon Guyot was genetically distinct from all basin transect samples (mean F sub(ST) = 0.120 plus or minus 0.03, P < 0.001 for all, and mean Nm = 2.0 plus or minus 0.6), and from the sample at the base of the seamount (F sub(ST) = 0.162, P < 0.001, and Nm = 1.3). The genetic differentiation of the crest populations of E. gryllus may be explained by either of two hypotheses: (1) strong differential selection acting on the crest population, causing it to diverge in genetic character from basin populations, and (2) rarity of dispersal and interbreeding between the crest and basin populations. If the latter is true (as seems more probable based on biological information and genetic evidence), dispersal of E. gryllus is predominantly horizontal, and there may be a seamount form of the species that is genetically, and perhaps taxonomically, distinct from the basin form.

Evidence for the Early Oligocene Formation of a Proto-Subtropical Convergence From Oxygen Isotope Records of New Zealand Paleogene Brachiopods. Palaeogeography Palaeoclimatology Palaeoecology 138(1-4): 43-68. 1998 Abstract: Using the oxygen isotope record in fossil brachiopods, we reconstruct Late Eocene through Early Miocene paleotemperatures of an eastern New Zealand shelf environment. Our results show a decline in temperature to a low of approximates 6degreeC in the Early Oligocene, of a magnitude similar to that of open-ocean isotopic studies from similar latitudes. However, the brachiopod-derived paleotemperatures are approximates 10degreeC lower than those inferred from occurrences of warm-water fauna and flora (e.g., large foraminifera, mangrove and coconut palms), which suggest a subtropical (20-23degreeC) climate throughout most of the New Zealand Oligocene. We propose that a proto-Subtropical Convergence (pSTC), with cool subantarctic water flowing along the eastern coast of the South Island, first developed in the Early Oligocene. The subtropical fauna and flora distribution patterns are consistent with this hypothesis. Warm-water biota (e.g., larger foraminifera, and mangrove trees) occur primarily on the west and north coasts of New Zealand in warm subtropical water characteristic of water north of the pSTC, similar to the modern Subtropical Convergence. We explain the occurrence of occasional subtropical taxa in Early Oligocene strata of the east coast of the South Island as a result of the north-south migration of the pSTC or the colonization of relict Surtseyan-type seamounts in local waters warmed by volcanic eruptions Burukovskij, R.N.

The absence of a rostrum and pereopod did not allow him to confidently identify these specimens. I also obtained a damaged specimen of this species from the Sala y Gomez Ridge (25 degree 38' S, 86 degree 43' W, depth 400 m, shrimp trap) (Burukovskiy, 1990). Recently, I obtained five specimens of this species in various degrees of preservation which are the basis for this description of a new species.

Scientia Marina 56(2-3): 125-130. 1992 Abstract: Stylasterids show a pronounced insular distribution pattern, being found primarily off small (less than 36,000 km2) oceanic islands, atolls, and archipelagos, and on seamounts and submarine ridges. Although lowered salinity and increased sedimentation may exclude stylasterids from the coasts of larger continental land masses, it is more likely that the availability of hard substrate and the low nutrient levels associated with steep-sided oceanic islands favor the establishment of stylasterids. Azooxanthellate Scleractinia, another calcified cnidarian taxon, have a broader distribution than stylasterids because they are assumed to be better competitors: having a greater dispersal ability, better sediment-shedding ability, and the ability of some to live on soft substrates Calder, D.R.

Assemblages of Hydroids (Cnidaria) From Three Seamounts Near Bermuda in the Western North Atlantic. Deep-Sea Research Part I: Oceanographic Research Papers 47: 1125-1139. 2000 Abstract: Three seamounts flanking the oceanic island of Bermuda were sampled for hydroids. Collecting was undertaken by submersible (SDL-1) and by dredge at depths between 48 and 107 m on the summits of Argus and Challenger banks. A shallower collection (< 20 m) from the pilings of a tower on Argus Bank was made using SCUBA. Major bottom types on both banks were aggregations of rhodoliths, limestone reefs, and areas of calcareous sand. Hydroids were ubiquitous, but quite sparse, on firm substrata. None was collected on sandy bottoms. Of 45 species identified from the two oceanic banks, over half (25) were found on both. On Bowditch Seamount, samples were obtained at depths between 1285 and 1381 m by dredge and grab. Of four species found, only one (Filellum serratum) occurred in shallower collections from Argus and Challenger banks. Most species (43 of 48) from the three seamounts have been reported elsewhere in the Western Atlantic Tropical region, and many (38 of 48) are known from Bermuda. No endemics were discovered, and no relicts or exotics were recognized. Gonophores in > 70% of the species are fixed sporosacs instead of free medusae. This conforms with a hypothesis that invertebrates of oceanic islands and seamounts tend to have short-lived pelagic larval stages, ensuring the greatest retention and conservation of propagules Carriol, R.P.

Can.Data Rep.Fish.Aquat.Sci., Issue #266, p. -34. 1981 Abstract: Bowie Seamount was explored using a vessel equipped with the Mustad autoline system. Rockfishes (Sebastes spp.) were the target species and were the dominant species in the catch. Sebastes aleutianus comprised 41% of the retained catch, followed by sablefish (Anoplopoma fimbria ) with 11% and S. ruberrimus with 10%. The primary species discarded was halibut (Hippoglossus stenolepis ) (69% of discard). Total retained catch was 6819 kg while discards amounted to 2,404 kg. Catch rates at the Seamount during favourable weather were higher than at inshore localities. Two days were spent fishing in the Langara Island area, due to inclement weather at the Seamount. Biological characteristics of rockfishes at the Seamount suggest that they have undergone little, if any, exploitation. The commercial and scientific importance of rockfish stocks on the Seamount is briefly discussed Carter, E.W. and B.M. Leaman.

AGSO Journal of Australian Geology & Geophysics 16(5): 677-699. 1997 Abstract: Samples from eight dredge hauls collected during BMR cruise 107 from several seamounts in the Vening Meinesz chain, south of Christmas Island, yielded calcareous nannofossils, foraminiferids, and fragmentary macrofossils with ages ranging from Late Cretaceous to Holocene. Many samples are mixtures, suggestive of debris flows, and some contain lithologies of various ages. The Late Cretaceous assemblages suggest shallow-water to upper bathyal depths. The seamounts were built up rapidly by volcanism, probably commencing during the Albian or Santonian, continuing through the Campanian, by which Lime they had shoaled, and ceasing during the Maastrichtian. Atolls comprising mounds of shelly algal biostromes dominated by rudists and Inoceramus had formed by the Maastrichtian. The sea was warm at this time, when the area was at latitudes far south of those of today. The Palaeogene assemblages suggest increasingly deeper depositional environments. The Paleocene is indirectly indicated by the presence of nannofloras of this age reworked into younger assemblages, but Eocene calcareous microfossils are well represented. Shallow-water assemblages (including large neritic benthic foraminiferids) are widespread in the late Early to early Middle Eocene samples, suggesting subtropical or tropical water temperatures. The fresh volcanic content in some samples hints at the possibility of renewed volcanism during the Eocene. The Oligocene is marked by pelagites containing nannofossils. Most of the Neogene assemblages are Late Miocene or younger, although some Middle Miocene nannofloras were recovered. Depositional depths appear to have been bathyal during this time, an accompaniment to seamount sinking and crustal and subcrustal cooling. Volcanism had ceased. Debris flows, however, continued to transport shallow-water sediments downslope. Holocene and present-day oozes mantle all previous deposits Charmasson, S.S. and D.P. Calmet. Distribution of Scavenging Lysianassidae Amphipods Eurythenes Gryllus in the Northeast Atlantic: Comparison With Studies Held in the Pacific. Deep-Sea Research Part A: Oceanographic Research Papers 34(9): 1509-1523. 1987 Abstract: Deep-sea scavenging amphipods, Eurythenes gryllus, were caught in the northeast Atlantic Ocean with baited traps attached on free-vehicle lines at different levels above the seafloor, in September 1983 and May 1984. Maximum catch rates occurred at altitudes less than or equal to 20 m and decreased rapidly above. An increase in size with increasing height of capture above the seafloor appeared for both females and males, females having a greater mean size than males. Small individuals were found generally at lower levels while larger specimens were caught at any level. In September, E. gryllus appeared larger on the NEA site (4800 m) compared to the Armorican Seamount location (3800 m). The mean size of E. gryllus and the proportion of females were higher in September compared to May, indicating that we may have sampled a younger population in May. The study of color distribution versus amphipod size ranges revealed that E. gryllus become colored when maturing. Although the proportion of pigmented amphipods increased with increasing height of catch, this variation was not statistically significant. Spatial and temporal variations in color may result from changes in the availability of certain foods. Comparisons with Pacific studies are made. (DBO) Chave, E.H. and B.C. Mundy. Deep-Sea Benthic Fish of the Hawaiian Archipelago, Cross Seamount, and Johnston Atoll. Pacific Science 48(4): 367-409. 1994 Abstract: More than 250 benthic fish taxa were photographed and videotaped by Hawaii Undersea Research Laboratory submersibles at depths between 40 and 2000 m in the Hawaiian Archipelago, Johnston Atoll, and Cross Seamount. Most of the 213 identified fish species occurred close to hard substrates with holes, ledges, or caves. Twenty-two species (notably the larger sharks, lutjanids, and carangids) are cosmopolitan. Seventy-six species are restricted to various Indo-Pacific areas, 64 in the Pacific, and 51 in the Hawaiian Archipelago including Cross Seamount and Johnston Atoll. There is a rapid decrease in the number of species from 200 to 400 m depth. One hundred eight species were seen 20 m deeper than previously reported. Eleven of the deeper-dwelling animals were found 20 m shallower than previously recorded. Faunal zones were not recognized at any depth. Species newly recorded in Hawai'i include Bathypterois grallator (Goode & Bean), Bodianus cylindriatus (Tanaka), Centrophorus cf. granulosus (Bloch & Schneider), Chaunax fimbriatus Hilgendorf, Caelorinchus spilonotus Sazonov & Iwamoto, Notocanthus sp., Paratrachichthys prosthemius Jordan & Fowler, Prognathodes guezei (Mauge & Bauchot), and Sladenia remiger Smith & Radcliffe. New species collected and reported elsewhere are Centrodraco rubellus Fricke et al., Epigonus glossodontus Gon, Owstonia sp., and Pseudanthias fucinus (Randall & Ralston). Caelorinchus sp. 2 and Callanthias sp. are probably undescribed. It appears that the Hawaiian deep-sea fish fauna has multiple origins and affinities with many regions Chen, C., R.C.

Deep-Sea Research Part A: Oceanographic Research Papers 39(2): 245-268. 1992 Abstract: A triangular CTD/ADCP survey was made across the Kuroshio southwest of Kyushu [Japan] aboard the R.V. Thompson during January 1986. Due to relatively poor navigation data, a simple averaging technique has been used to convert the ADCP data taken between CTD station pairs into an average absolute velocity normal to the station pair, with a maximum error varying from about .plus-minus. 5 cm s-1 to less than .plus-minus.0.1 cm s-1 depending on the type of nagivation data. The average ADCP velocity at 60 m (or 10 m over the shelf) was then used as the reference velocity to calculate the absolute geostrophic velocity through the sides of the study triangle. The results show that the ADCP velocity shear was in reasonably good agreement with the geostrophic shear of the Kuroshio. The Kuroshio entered the study triangle as a coherent current and then split around a tall seamount into two branches as it left the area. The volume transport of the Kuroshio southwest of Kyushu in January 1986 was 30.3 .plus-minus. 2.0 Sv, and the advective temperature transport was 27.6 .plus-minus. 1.8 .times. 1014 W. These values are similar to those reported for the Gulf Stream in the Florida Strait, and a roughly linear correlation exists between temperature and volume transports in both regions. Mass conservation within the study triangle allowed construction of a stream function that showed the presence of cyclonic and anti-cyclonic mesoscale eddies to the north and northwest of the core of the Kuroshio. Potential vorticity estimated from the absolute geostrophic velocity field was conserved along streamlines on potential density surfaces except perhaps near a seamount where curvature vorticity must be considered, and the path of the Kuroshio could be traced by the core of maximum potential vorticity. Finally, the Kuroshio was potentially unstable as it flowed along the continental margin in the Okinawa Trough because the gradient of potential density surfaces changed sign across the Kuroshio. This helps explain the mesoscale frontal and eddy features observed in the cyclonic side of the Kuroshio in the East China Sea Chen, C.H.

Ekologiia morya(23): 16-23. 1986 Abstract: Data are presented on particulate protein content in the upper 500 m layer of the Southeast Atlantic. The absolute values varied from 9.7 to 397.3 mu g/l. The maximum concentrations were observed in the Benguela Current and the subantarctic front area. Low concentrations were confined to the inner part of the subtropical convergence zone, above the steep ledge of the continental slope of West Africa and above the Vema Seamount and Discovery Tablemount. The content of protein in suspended organic matter was found to be closely related to phyto- and bacterioplankton abundance Cho, B.C. Bacterial Biomass and Production in the Water Column Over Two Central North Pacific Seamounts. Journal of the Korean Society of Oceanography 26(3): 255-261. 1991 Abstract: Bacterial abundance and production in the water column over two seamounts (Horizon Guyot and Magellan Rise) in the central North Pacific were studied in March 1987. Bacterial abundance (0.9-2.3 .times. 108 l-1) in surface waters during the study period were in the lower limit of the values reported for oligotrophic areas. Further, bacterial abundance in mesopelagic zone (mostly < 5 .times. 107 l-1) was much lower than that reported from other tropical areas. Bacterial production (20-466 ng C l--1 d-1) in surface waters was also low compared to other oligotrophic oceanic environments. However, comparison of bacterial production with the earlier reported values of primary production from these regions suggested a significant role of bacteria in the utilization of organic matter in the surface waters. Though data on distribution of bacterial production are limited in this study, further studies on spatial distribution of bacterial production on both small and large scales in very oligotrophic aquatic environments are suggested to be necessary Christie, D.M., R.A.

Nature 355(357): 246-248. 1992 Abstract: The volcanic islands of the Galapagos archipelago are the most recent products of a long-lived mantle hotspot. Little is known, however, of the submarine Galapagos platform on which the islands are built, or of the Cocos and Carnegie submarine ridges produced by past motion of the Cocos and Nazca plates across the hotspot. In 1990 we surveyed selected areas around the Galapagos platform and as far east as 85 degree 30'W on the Carnegie ridge, where we dredged abundant well-rounded basalt cobbles from a small seamount with a terraced summit region. Cobbles were also dredged from several other seamounts. We interpret these features, especially the presence of cobbles, as evidence for erosion near sea level and conclude that these seamounts were volcanic islands before subsiding to their present depths. Radiometric ages for these drowned islands range from 5 to 9 Myr, consistent with predicted plate motions. They indicate that the time available for speciation of Galapagos organisms is much longer than the age range of the existing islands Clague, D.A.

Fisheries for Orange Roughy (Hoplostethus Atlanticus) on Seamounts in New Zealand. Oceanologica Acta (Paris) 22(6): 593-602. 1999 Abstract: Major commercial fisheries for orange roughy (Hoplostethus atlanticus) occur on seamount features, which are widely distributed throughout the New Zealand region. When the fishery developed in the late 1970s to early 1980s, it occurred mainly on flat bottom, but over time has become more focused on seamounts. In the 1995-96 fishing year, it is estimated that about 70 % of the catch of orange roughy within the New Zealand EEZ was taken from seamounts. Seamounts on the Chatham Rise have been fished for over ten years. Examination of commercial catch and effort data show strong declines in catch rates over time, and a pattern of serial depletion of seamount populations, with the fishery moving progressively eastwards to unfished seamounts along the southern margins of the Rise. Catch rates on seamounts in other regions of New Zealand have also generally shown a similar pattern of rapid decline. There is growing concern over the impact of trawling on seamounts, and the effects this can have on the benthic habitat and fauna, and the long-term sustainability of associated commercial fisheries Clark, M.R., O.F. Anderson, R.I.C.C. Francis, and D.M. Tracey. The Effects of Commercial Exploitation on Orange Roughy (Hoplostethus Atlanticus) From the Continental Slope of the Chatham Rise, New Zealand, From 1979 to 1997. Fisheries Research (Amsterdam) 45(3): 217-238. 2000 Abstract: Orange roughy (Hoplostethus atlanticus) is a recently exploited species, fished by trawling at depths of 700-1200 m on the continental slope around New Zealand. In this paper, changes in the major New Zealand orange roughy fishery on the Chatham Rise during a 19-year period are examined. Data from research trawl surveys and commercial fishing returns from 1979 to 1997 were analysed, and changes in the population described. The distribution of orange roughy showed a marked contraction, and aggregations became largely centred around seamounts or very localised areas of the slope. The biomass of orange roughy, measured by trawl survey and commercial catch-per-unit-effort indices, declined substantially, and in 1997 was estimated to be about 20% of virgin levels. Most bycatch species also declined in abundance, with no indication of species replacement. Size structure of the population did not change markedly over the period. Timing of spawning in July, and the pattern of gonad development, were also consistent over the years. There was no change in size or age at maturity. Prey composition remained similar. Biological changes may not have been apparent because orange roughy is a long-lived, slow-growing species, with low productivity. There could be a long response time of the population to fishing pressure Clouard, V. and A. Bonneville. How Many Pacific Hotspots Are Fed by Deep-Mantle Plumes? Geology 29(8): 695-698. 2001 Abstract: The Pacific plate is usually considered to host 14 hotspots, but most of this volcanism does not seem to originate from deep-mantle plumes. To reach this conclusion, we tried to establish how many of the seamount alignments on the Pacific plate correspond to classic hotspots, i.e., long-lived hotspots linked to oceanic basaltic plateaus. We retraced the tracks of the 14 Pacific hotspots by using (1) the absolute stage poles representing the Pacific plate absolute motion since 145 Ma, (2) an updated compilation of radiometric ages of seamounts and oceanic plateaus totaling 266 seamounts or islands, (3) the detailed bathymetry of the Pacific Ocean, and (4) the present locations of the hotspots. This analysis allowed us to correlate only three hotspots with the beginning of their tracks possibly corresponding in space and time to an oceanic plateau: Easter to the eastern Mid-Pacific Mountains, Louisville to the Ontong Java plateau, and, with less confidence, Marquesas to Hess Rise and Shatsky Ridge. In addition, the Hawaii hotspot has produced long-lived volcanism. These four are the only classic hotspots on the Pacific plate. However, seven hotspots present short tracks (<35 m.y.) that cannot be traced to an oceanic plateau and thus are not related to any deep-mantle phenomena: Foundation, Macdonald, Pitcairn, Rarotonga, Rurutu, Samoa, and Society. The two northeast Pacific hotspots, Kodiak-Bowie and Cobb, and the Caroline hotspot are unclassifiable because of close proximity to a subduction zone where the prior history of volcanism has been lost Codiga, D.L.

Shallow-Water Fishes of Walters Shoals, Madagascar Ridge. Bulletin of Marine Science 48(1): 1-22. 1991 Abstract: Walters Shoals is an isolated seamount reaching to within 18 m of the surface, and is located about 400 nautical miles south of Madagascar and 600 nm east of Souther Africa. It is part of a chain of seven islands and seamounts extending along the West Wind Drift from Gough and Tristan da Cunha in the South Atlantic to Amsterdam and St. Paul in the southern Indian Ocean. Fishes were collecting during VITYAZ cruise 17 in December 1988. The shallow-water fish fauna comprises about 20 species and is composed of three elements: endemics (7-8 species), wide-spread temperate or subtropical species (5-6), and tropical Indo-West Pacific reef species (6). Three species, and carangid, Trachurus longimanus, a cheilodactylid, Acantholatris monodactylus, and a labrid, Nelabrichthys ornatus, are endemic to the West Wind Drift islands. A serranid, Lepidoperca coatsii, is known from four of the island groups and may also occur at Walters Shoals. Another serranid, Serranus novemcinctus, occurs only at the four Indian Ocean islands and seamounts. The common Gymnothorax is an undescribed species, probably endemic. A specimen of scorpaenid had been described as Scorpaenodes immaculatus, also probably endemic. A second species of Gymnothorax and the species of Plagiogeneion may also be endemic species. Thus, 30-40% of the shallow water fish fauna of Walters Shoals is endemic to some part of this chain of islands and seamounts. The species of Carcharhinus, Cheilopogon, Polyprion, Seriola, and Scomber are wide-spread in temperature or subtropical waters. Plectranthias longimanus, Apogon semiornatus, Chromis weberi, C. axillaris, Pterois cf. miles, and Kentrocapros rosapinto are trophical Indo-West Pacific reef fishes. The fish fauna of Walters Shoals links Brigg's Tristan-Gough Province of his southern South America Cold Temperate Region with the Amsterdam-St. Paul Province of his Southern African Warm Temperature Region into a single zoogeographic province, which is here called the West Wind Drift Islands Province Collott, J.-Y., T.

Relationship Between Phytoplankton Production and the Physical Structure of the Water Column Near Cobb Seamount, Northeast Pacific. Deep-Sea Research Part I: Oceanographic Research Papers 42(6): 993-1005. 1995 Abstract: The objective of this study was to determine the impact of the Cobb Seamount (northeast Pacific) on phytoptankton biomass and primary production. In August 1991, we sampled along six 30 km spokes radiating outward from the summit of Cobb Seamount. Surface chlorophyll a (Chl a) and incident light conditions were relatively uniform over this mesoscale sampling grid, but primary production varied over a ten-fold range. Statistical analyses linked these production variations to a subsurface ( gt 50 m) thermohaline front skirting the flanks of the seamount. The thermal stratification of surface waters ( lt 50 m) also changed across the front, generally increasing toward the seamount. These physical changes in turn were associated with a shallowing and intensification of subsurface Chl a maxima, increases in diatom biovolume, and increases in production to biomass ratios. Although nutrient isolines domed slightly upward over the seamount, this physical feature did not seem to enrich surface waters or stimulate production. It appeared that growth and production rates were enhanced by increased stability of the upper water column that led to an improved subsurface light regime. Possible associations of these physical-biological interactions with the seamount are discussed Coyle, K.O., G.L. Hunt, M.B. Decker, and T.J. Weingartner.

Bulletin of Marine Science 53(3): 973-984. 1993 Abstract: Four mysis stages of a species of Gennadas, very likely G. valens, are described and illustrated, and their differences from the only described larvae of a species of this genus, G. elegans, are discussed. The larvae were collected downstream and inshore from a seamount on the continental shelf in the Florida Keys between 24.5 degree N, 80.7 degree W and 25 degree N, 80.3 degree W. Adults and juveniles of species of Gennadas have previously been reported as strong diel vertical migrators aggregated at depths of 550-950 m during the day and 75-425 m at night; and larvae have been reported as common between 50 and 100 m deep. This is the first description of larvae of a species of Gennadas other than G. elegans and the first report of larvae of a species of Gennadas at less than 50 m in depth Crosnier, A.

Indo-Pacific Fisheries Commission.Proceedings, 19th session, Occas.Pap., edition 17, Noumea (New Caledonia), p. -12. 1980 Abstract: This paper presents a brief review of the Outer Reef Artisanal Fisheries Project which terminated in 1977, and describes in more detail the Commission's current project, the Deep Sea Fisheries Development Project. The aim of the Deep Sea Fisheries Development Project is to encourage development of a small-scale fishery for deep water bottom fishes occurring on the outer reef slopes and on sea mounts in depths of 100-400m. The project spends several months at one place under the control of a master fisherman. It demonstrates the techniques of deep water droplining using wooden handreels, monofilament line and wire terminal rigs. Fishing is done from local boats, either government or private. Local fishermen receive on-the-job training in all aspects of the operation. Between March 1978 and March 1980 the project visited American Samoa, Tonga (twice), Niue (twice), Yap, Tanna (New Hebrides), Kosrae, Palau, New Caledonia and Papua New Guinea. Lutjanid fishes comprised about half the catch by weight, of which Etelis oculatus, E. carbunculus and Pristipomoides sp. were the most important. Other important types were carangids, serranids, lethrinids and gempylids. The average catch in kg per reel per fishing hour varied from 2.8 at Niue to 9.6 at Kosrae. It is considered that in several places the catch rates achieved are sufficient to make this type of fishing economically viable d'Hondt, J.-L.

Calculated annual diet of boar fish occuring in the Kinmei Seamount area suggests that macroplankton biomass brought with currents does not fully compensate for energy expenditures of the fish and should be summed up with the local plankton generations in vicinity of seamounts and advection from the adjacent areas Darnitskij, V.B. and N.I.

The synoptic-scale instability of biological communities is largely attributable to the rearrangement of hydrophysical fields, primarily to the dynamics of eddy systems. The synoptic variability of hydrological parameters near seamounts is more intensive in comparison with the background conditions due to the proximity of topographic and satellite eddies. Their interaction is complicated by the intensification of wave processes. The hydrological processes have a considerable effect on the structure and variability of plankton communities in the thalassobathyal zone causing redistribution of fish DARNITSKY, V.B.

Deep-Sea Research Part A: Oceanographic Research Papers 39(7-8): 1139-1145. 1992 Abstract: We report results of a CTD and chlorophyll a survey from Cobb Seamount, a shallow seamount in the northeast Pacific. Out results show a several-fold increased in the standing crop of chlorophyll a is centered over the seamount. Current meter and drifter data indicate an anticyclonic deflection of deep currents around Cobb consistent with a theoretical stratified Taylor cone. Cobb differs from other seamounts where similar phenomena have been reported (OWENS and HOGG, 1980, Deep-Sea Research, 27, 1029-1045; GOULD et al., 1981, Deep-Sea Research, 28, 409-440; GENIN and BOEHLERT, 1985, Journal of Marine Research, 43, 907-924) in that its summit penetrates well into the euphotic zone. A Taylor column existing at such shallow depths could locally enhance primary production, providing a significant source of energy for higher trophic levels on the seamount. Indirect evidence for such a scenario comes from observations of a high biomass benthic community on Cobb Seamount Dower, J.F. and D.L. Mackas. "Seamount Effects" in the Zooplankton Community Near Cobb Seamount. Deep-Sea Research Part I: Oceanographic Research Papers 43(6): 837-858. 1996 Abstract: Oceanic seamounts often support large nektonic stocks. Since the mid-1950s it has been believed that this high productivity results, in part, from biological response to the physical interaction between oceanic currents and the abrupt topographic profiles represented by most seamounts. The "classic theory" for the production/maintenance of seamount nektonic stocks suggests that (i) the combination of localized upwelling and the trapping/concentrating action of closed anticyclonic vortices (i.e. Taylor cones) enhance local primary production, (ii) thereby promoting local secondary productivity that, (iii) supports local nektonic populations. Here we test one element of this theory: whether proximity to a shallow seamount is associated with changes in zooplankton abundance and species composition. Zooplankton samples were collected near Cobb Seamount, a shallow ( lt 100 m) northeast Pacific seamount 50-km west of Vancouver Island. Both upwelling and closed recirculations occur at Cobb Seamount, but the latter is confined to depths gt 100 m and is not an effective retention mechanism. Total zooplankton abundance did not vary significantly on- versus off-seamount. However, using a variety of nonparametric multivariate techniques we demonstrate that a "seamount effect" on zooplankton-community composition is detectable up to 30 km from the seamount summit. This effect is super-imposed on (and locally much stronger than) the expected slow decline in resemblance as between-sample geographic distance increases. Possible mechanisms by which this effect operates include: differential growth or reproduction, differential mortality and behavioral or migratory effects. The on-off seamount differences are accounted for largely by the increased relative abundances of two fast-growing opportunists, doliolids (Dolioletta sp.) and larvaceans (Oikopleura sp.), near Cobb Seamount. Predation pressure from seamount fish and active avoidance of the seamount by zooplankton may also play a role in generating the seamount effect. The absence of an effective trapping mechanism and the fact that total zooplankton abundance does not increase near the seamount lead us to conclude that the bottom-up model of localized energy transfer proposed under the "classic hypothesis" is incorrect for Cobb Seamount: nektonic stocks at Cobb Seamount (and, possibly, other shallow seamounts) are more likely supported by flow-through (i.e. advected) rather than local production Dower, J.F.

Estimation of Current Velocity and Direction From Orientation of Conical Radiolarians in Lower Jurassic Bedded Cherts From Southwest Japan: Indications of Eddy-Driven Sedimentation. Marine Micropaleontology 30(1-3): 197-214. 1997 Abstract: Paleo-current activity of deep marine environments was analyzed by studying the sedimentation characteristics of conical-shaped radiolarian tests from Lower Jurassic bedded cherts in the Inuyama area, Central Japan. As representatives of conical-shaped radiolarians, Parahsuum spp. were analyzed in a flume experiment. The results indicate that the preferred azimuth orientation of the shells is correlated to the current velocity. This result is used to evaluate current velocity and direction in Lower Jurassic bedded cherts. The bedded cherts examined and ranging from the Triassic-Jurassic boundary to Toarcian (Lower Jurassic) are divided in ascending order into red, red-green, green and black to gray bedded chert units. Supplementary sections of the Lower Jurassic are also examined. Estimated current velocities within the red bedded chert sequences are usually higher than in the black bedded chert sequences, although current velocity varies in each horizon. Current direction within the examined sections varies between chert beds. Within single beds of the red-green and black cherts, current velocity has also been examined in intervals of less than 1 mm thickness. Examination of red-green bedded cherts reveals that current velocity altered rhythmically even during the deposition of a single bed. Within black bedded cherts, one bed shows slower current with varied current directions, while another shows rather rapid current with steady orientation. Faster currents during the deposition of red and red-green bedded cherts are concordant to inferred stagnant conditions in black bedded cherts with associated weak bottom-water circulation. The measured current direction generally varies both between beds and within single beds, which means bottom currents were not uniform direction but had a variety of directions in the sedimentary basin. Bedded cherts are representative of high productivity by silica-precipitating biogenic plankton and may be formed on topographic highs such as seamounts, where nutrients are supplied at a high rate by upwelling. The variation of current velocity and direction indicates a depositional basin with an irregular topography where current eddies may have formed Dubochkin, A.S. and A.N. Kotlyar. On the Feeding of Alfoncino (Beryx Splendens ). Journal of Ichthyology 29(5): 1-8. 1989 Abstract: The quantitative and qualitative composition of the diet of alfoncino (Beryx splendens ) associated with the Kito and Naska seamounts are presented. The basic diet consists of crustaceans and fishes. A tendency for fish to predominate in the diet was noted in larger fish. Alfoncino represent consumer trophic level III assuming the role of nektonic predator Dugdale, R. Spatial and Temporal Variability in Nutrient Patterns, Productivity and Algal Species. p. 3. 1998 Abstract: This award funded a graduate student to complete analysis of data obtained during cruises made during the ONR funded TOPO ARI cruises (1989-1991) to Fieberling Guyot. The analysis specifically addressed a) using the dominant pigments to identify the phytoplankton groups contributing to productivity station by station, to examine if there were differences above, on the side and away from the seamount, and b) identifying the nutracline at each station using detailed nanomolar and micromolar measurements, and overlaying the fluorescence maxima data to compare relative nutracline/chlorophyll maxima relationships of Fieberling with those at shallower topographical features. N- 15 uptake showed that depth-integrated values of ammonium uptake were greater than for nitrate-the ecosystem is a recycling microbial loop system. The pigment data supported this with pigments characteristic of small-celled autotrophs (typically that use ammonium as a nitrogen source rather than nitrate), dominating after chlorophylls a and b, i.e. zeaxanthin (contained by phycobilin-containing cyanobacteria); 1 9-hexanoyfoxyfu
