Landfast sea ice, sea ice that is held stationary against the Antarctic continent, links firmly with many key climate processes, but its importance is only being fully realized as its extent dwindles.
Antarctic ice drives crucial deep-ocean currents that help regulate Earth’s climate. But the system is slowing down.
Nutrients from the seabirds’ guano fuels the growth of carbon-storing phytoplankton, but penguin populations have plunged in the past 4 decades.
Projected changes to El Niño will likely accelerate warming of the deep oceans around the Antarctic, supplying heat that could drive ice loss and sea level rise.
Cold surface water in the Southern Ocean is a critical component in ocean carbon uptake. A new study profiles it using state-of-the-art research techniques.
South African scientists map uninhabited islands in the Southern Ocean.
New measurements show the macro- and microphysical characteristics of the clouds and precipitation over the data-space regions of the Southern Ocean.
New research could help inform future studies of how the release of carbon dioxide from the Southern Ocean might affect global climate change.
Poorly understood ice multiplication processes, not aerosols, may determine the microphysical properties of climatologically important clouds over the Southern Ocean.
Data from a long-distance research cruise provide new insights into carbon cycling in the eastern Pacific and Southern Oceans.
