Marine organisms Southern Ocean face shallower zone life
2019/11/22
Marine organisms in the Southern Ocean may find themselves between a rock and a hard place by the end of the century as ocean acidification creates a shallower zone for life.The new research results, ...

Scientists Identify Source Mysterious Low-Frequency Sound Heard for Decades Southern Ocean
2014/5/13
Scientists have conclusive evidence that the source of a unique rhythmic sound, recorded for decades in the Southern Ocean and called the “bio-duck,” is the Antarctic minke whale (Balaenoptera bonaere...
Large-scale geographical variation in prokaryotic abundance and production in meso- and bathypelagic zones of the central Pacific and Southern Ocean
Large-scale geographical variation prokaryotic abundance production meso- and bathypelagic zones central Pacific Southern Ocean
2014/4/2
Heterotrophic production and abundance of prokaryotes (i.e.,BacteriaandArchaea) in meso- (200–1000 m) and bathypelagic (.1000 m) zones were measured at 31 stations along meridional transects of the ce...
Biogeneration of chromophoric dissolved organic matter by bacteria and krill in the Southern Ocean
chromophoric dissolved organic matter bacteria krill the Southern Ocean
2014/4/17
Chromophoric dissolved organic matter (CDOM), the optically active fraction of dissolved organic matter, is primarily generated by pelagic organisms in the open ocean. In this study,we experimentally ...
Can photoinhibition control phytoplankton abundance in deeply mixed water columns of the Southern Ocean?
photoinhibition control phytoplankton abundance deeply mixed water columns the Southern Ocean
2014/4/17
To study how natural Southern Ocean phytoplankton communities acclimate to rapid fluctuations in irradiance levels that result from deep wind-driven mixing of the upper water column, we measured their...
Isotopic niches and trophic levels of myctophid fishes and their predators in the Southern Ocean
Isotopic niches trophic levels myctophid fishes their predators in the Southern Ocean
2014/4/16
We report the trophic structure of a myctophid assemblage by measuring theisotopic niches of 14 species living in Kerguelen waters, southern Indian Ocean. Most of the species show distinct isotopic ni...
Enhanced viral production and infection of bacterioplankton during an iron-induced phytoplankton bloom in the Southern Ocean
Enhanced viral production infection of bacterioplankton iron-induced phytoplankton bloom Southern Ocean
2014/4/18
We followed the viral response to Fe-enrichment over 3 weeks during the second iron-enrichment experiment (EisenEx) in the Southern Ocean. Although viral abundance increased in a rather constant way d...
