OS024 - Sources and consequences of Southern Ocean freshening: Toward synthesising observations and modelling:
https://agu.confex.com/agu/fm20/prelim.cgi/Session/105151
The Southern Ocean is consistently freshening, particularly in the upper layers and near the Antarctic coast. Freshening has been attributed to an increase in precipitation, basal melting of ice shelves and enhanced sea-ice melt and export. Freshening has also been observed in the abyssal Antarctic bottom water, formed close to the Antarctic coast and exported globally. The exact proportionality is highly uncertain, but all these processes contribute to increasing sea level rise and the formation of sea ice through strengthening surface stratification. As the climate system continues to warm the relative magnitude of these processes may change leading to uncertain impacts on polar and global climate.
