Antarctic Bottom Water (AABW) in the Australian Antarctic Basin has become fresher and lighter since the late 1960s, with largest changes observed near the sources of AABW. The volume of AABW with neutral density (n) > 28.30 kg m-3 decreased by 50% between 1969-1971 and 2008-2012, thinning at a r...
