Sea ice cores were obtained from eleven fast ice stations and one floe in the Weddell Sea, Antarctica in January-February 1985. All cores from the north eastern part of the Weddell Sea contained numerous living and dead planktic foraminifers of the species Neogloboquadrina pachyderma (Ehrenberg), wh...
