VALIDATION OF ATMOSPHERIC HEAT BUDGET PARAMETERS IN THE WESTERN INDIAN SECTOR OF THE SOUTHERN OCEAN
Remote sensing Atmosphere Databases Marine Statistics Analysis Comparison Satellite
2015/12/28
The work reports validation of numerical weather forecasts (NWF), QuikSCAT-based wind speed and AMSR-E sea surface temperature (SST) for the surface atmospheric boundary layer in the Indian sector of ...
The first scientific exploration of the Antarctic dates to the end of the seventeenth century, when Sir Edmund Halley ventured just south of the Polar Front (about 60°S). During the following century,...
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...
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...
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...
Trends in Latent and Sensible Heat Fluxes over the Southern Ocean
Southern Ocean Antarctic Oscillation Pacific-South America Teleconnection
2013/2/26
In this study, the trends in latent and sensible heat fluxes (LHF and SHF) over the Southern Ocean (oceans south of 35?S) and the contributions of the Antarctic Oscillation (AAO), the Pacific-South Am...
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...

2010/1/21
In the Bransfield Strait, representing a mixture of waters from the Weddell Sea and the Antarctic Circumpolar Current (ACC), concentrations of DFe were ~0.4 nM and of TaLFe ~1.7 nM. The highest concen...
