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...
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 Impact of Southern Ocean Sea Ice in a Global Ocean Model
Southern Ocean Global Ocean Model Sea Ice
2008/10/24
Most of the Southern Ocean (SO) is marginally stably stratified and thus prone to enhanced convection and possibly bottom-water formation whenever the upper ocean is cooled or made more saline by ice ...
