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, ...

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...
Southern Exposure: New Paleoclimate Insights From Southern Ocean and Antarctic Margin Sediments
Southern Ocean Antarctic Margin Sediments
2015/7/15
Much of what is known about the evolution of Antarctica's cryosphere in the geologic past is derived from ice-distal deep-sea sedimentary records. Recent advances in drilling technology and climate pr...

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 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...
