Explaining Cold and Fresh Southern Polar Ocean Surface Waters

by P. Rizzoli 6 May 202017 August 2022

Global climate models do not reproduce observed trends of the Southern polar ocean surface, but an increase in wind-transported sea ice that melts and inhibits mixing may account for the disparity.
