Extraordinarily high biomass benthic community on Southern Ocean seamounts
We describe a previously unknown assemblage of seamount-associated megabenthos that has by far the highest peak biomass reported in the deep-sea outside of vent communities. The assemblage was found at depths of 2-2.5 km on rocky geomorphic features off the southeast coast of Australia, in an area near the Sub-Antarctic Zone characterised by high rates of surface productivity and carbon export ...
متن کاملBenthic Ostracods of Skogsbergiella (Myodocopina: Cylindroleberididae) from the Southern Ocean.
Skogsbergiella tetrathrix sp. nov. and S. species A, species of the family Cylindroleberididae are described from the Drake Passage (59°21.97´S - 60°4.27´W to 59°22.55´S - 60°4.01´W, depth 2372-2380 m) and Weddell Sea (75°49.9´S-27°31.7´W to 74°51.55´S-27°40.3´W, depth 467-475m) respectively. Skogsbergiella tetrathrix sp.nov. is very close to S. macrothrix Kornicker, 1975 but differs by greate...

متن کاملSouthern Ocean Overturning Role in Modulating High Southern Latitude Climate and Atmospheric CO2 on Millennial Timescales
During the last glacial period and particularly Marine Isotope Stage 3, North Atlantic Deep Water (NADW) formation weakened significantly on a millennial timescale leading to Greenland stadials (Kissel et al. 2008). Ice core records reveal that each Greenland stadial is associated with a warming over Antarctica, so-called Antarctic Isotope Maximum (AIM) (EPICA and Community Members 2006). Recen...
متن کاملMegafaunal composition of cold-water corals and other deep-sea benthos in the southern Emperor Seamounts area, North Pacific Ocean
Recent developments in deep-sea surveys have revealed the widespread distribution of cold-water corals over the deep-sea floor of the world ocean. There are no reports, however, concerning the taxonomic composition of cold-water corals and other benthic megafauna in the southern Emperor Seamounts area of the North Pacific Ocean. We analyzed benthic samples collected from a research vessel durin...
