Antarctic Bottom Water salinity response to increasing ice sheet melting ...
<!--!introduction!--> Ice sheet melting into the Southern Ocean increases the upper ocean stratification and sea ice production, and thus can change the formation and properties of the Antarctic Bottom Water (AABW). Indeed, both the AABW freshening, and sea ice expansion have been observed in...
