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...
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...

Baroclinic Volume Transport in the Southern Ocean
Baroclinic Volume Transport Southern Ocean historic hydrographic data
2009/2/7
A new map of the baroclinic volume transport to 3000 m has been produced for the Southern Ocean, making use of all available historic hydrographic data in the area. The map complements the geopotentia...
The Southern Ocean Thermohaline Circulation：A Numerical Model Sensitivity Study
primitive equation model two-dimensional Southern Ocean Thermohaline Circulation
2008/12/30
A two-dimensional primitive equation model is developed to study the thermohaline circulation of the Southern Ocean. The primary objectives are to identify those elements of the ocean climate model im...
Potential Vorticity Constraints on the Dynamics and Hydrography of the Southern Ocean
Southern Ocean Dynamics Hydrography potential vorticity
2008/12/17
Constraints on the hydrography and geostrophic velocity shear of the Southern Ocean implicit in its potential vorticity field are discussed and illustrated by diagnostic study of observed and modeled ...
Surface Eddy Momentum Flux and Velocity Variances in the Southern Ocean from Geosat Altimetry
Surface Eddy Momentum Flux Southern Ocean Velocity Variances Geosat Altimetry
2008/12/16
Satellite altimetry has previously been used to map the magnitude of the surface eddy variability of the global oceans, but the direction of the time-variable velocities have been more difficult to de...
