Poorly understood ice multiplication processes, not aerosols, may determine the microphysical properties of climatologically important clouds over the Southern Ocean.
Eight hundred meters below the West Antarctic Ice Sheet, microbes in subglacial Lake Whillans create organic carbon that helps power the Southern Ocean’s vast food chain.
Modeling icebergs as Lagrangian elements held together by numerical bonds provides insights into coupled exchanges of heat, freshwater, and momentum between large icebergs and the ocean.
For the first time, researchers combine estimates of sea surface height and circulation patterns in both ice-covered and ice-free regions of the Southern Ocean.
Data from instruments mounted on elephant seals reveal that melting ice flushes fresh water into the Southern Ocean, suppressing an important arm of the global ocean circulation belt.
How much does the Weddell Gyre contribute to the Global Overturning Circulation?
