New study redefines understanding of where icebergs leave meltwater in the Southern Ocean（图）
redefines understanding icebergs meltwaterin Southern Ocean
2021/1/8
Some icebergs that break off Antarctica are massive -- the size of New York City -- but these floating cities of freshwater have been largely ignored in climate models. A new study by scientists at th...
Marine organisms in Southern Ocean will face shallower zone for life（图）
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, ...

Flying lab Southern Ocean appetite for carbon
2016/1/8
A team of scientists supported by the National Science Foundation (NSF) will launch a series of research flights over the remote Southern Ocean this month to better understand just how much ...
Research spotlights a previously unknown microbial 'drama' playing in the Southern Ocean
Research spotlights previously unknown microbial drama Southern Ocean
2015/8/4
A team of marine researchers funded by the National Science Foundation (NSF) has discovered a three-way conflict raging at the microscopic level in the frigid waters off Antarctica over natural resour...
Bioactive trace Metal distributions and Biogeochemical controls in the Southern ocean
Metal distributions Biogeochemical controls
2015/7/15
Extensive sampling in many regions of the Southern Ocean has
demonstrated that surface water concentrations of dissolved Fe are low enough
to limit phytoplankton growth. In contrast, there is curr...
improving the Quality and Accessibility of current profile Measurements in the Southern Ocean
current profile Measurements Southern Ocean
2015/7/15
it takes more
than the Adcp itself, however, to yield good
current measurements. The end result depends
on how and where the sonar is installed; on
the quality of ancillary information includi...
The 1962–1992 period spanning the research vessel Eltanin/
Islas Orcadas expeditions to Ice Station Weddell, and the following World Ocean
Circulation Experiment, may be viewed as the closing phase...
Various human activities, including
fossil fuel combustion and forest clearing, emit
about eight petagrams (or billion tons) of carbon
in the form of CO2 into the atmosphere annually.
The glob...
The Southern Ocean includes the only latitude band where the ocean circles the earth unobstructed by continental boundaries. This accident of geography has profound consequences for global ocean circu...
Scientists Identify Source of Mysterious Low-Frequency Sound Heard for Decades in the Southern Ocean
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...
