WebIce formation increases sea-surface salinity and produces High Salinity Shelf Water (HSSW) that presents a salinity value greater than 34.62. HSSW is formed mostly in the TNB area during winter ( Budillon et al., 2003 ), spreads northwards following the Drygalski Basin, and finally flows off the shelf near Cape Adare, where it mixes with CDW to ... WebThe formation of High-Salinity Shelf Water (HSSW), which is the major source of Antarctic bottom water (AABW), has been observed in Terra Nova Bay (TNB) in Antarctica.
