Southern Ocean (modified from Petschick et al. 1996).
Since we cannot distinguish water mass properties from clay mineralogy we refer to CPDW and
AABW as southern-source deep and bottom water. This term is also applied when discussing paleowater mass configurations. Accordingly, equivalents ofpaleo-NADW are called northern-source
deep water. So the modem deep water configuration in the South Atlantic reveals a pronounced
