SPORADIC INCREASE OF PARTICLE SEDIMENTATION AT THE ICE EDGE OF THE ANTARCTIC OCEAN DURING THE AUSTRAL SUMMER 1994-1995 (18th Symposium on Polar Biology)
Time-series sediment traps were deployed at depths of 537 m, 796 m, 1259 m, 1722 m and 2727 m at ice edge of the Antarctic Ocean (64°42'S, 139°58'E) from 26 December 1994 to 20 January 1995. During a short period from 7 to 9 January, a sporadic flux increase within a few days in terms of t...
