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 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, ...
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 ...
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...
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...
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 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...
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...
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 ...
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...
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...
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...
