Interdecadal water mass changes in the Southern Ocean between 30E and 160E
using the Japanese Antarctic Research Expeditions and historical hydrographic observations from the 1950s to 1990s. Freshening and cooling occurred on the neutral density surfaces of 27.0 kgm3 equatorward of Sub-Antarctic Front. Results for the area south of the Polar Front show warm and saline anom...
