Abstract

WARMING OF WATERS SURROUNDING ANTARCTICA

Increased melting of the Antarctic ice sheets will cause global sea level rise. Basal ice shelf melt drives Antarctic ice sheet loss.This basal ice shelf melt due to ocean-ice interaction is connected to Antarctic Shelf Bottom Water temperatures and thus expected to accelerate in a climate that is warming. We map spatial variability and temporal trends in ASBW properties since 1975 and compare these to temperature and shoaling trends observed in CDW at the continental slope. Regions of observed ASBW warming are similar to those reported to have increased ice shelf melt. The observed warming will impact ice sheet melting, thus sea level rise, bottom water formation and likely modulate Southern Ocean primary production.
