The mass of sinking particles forming the flux maximum sank down to the deepest trap (2727 m) within 7-11 days, indicating that about 5% of these particles were transported downward to the bottom with the sinking rate of 199-313 m d^<-1> (mean 243 m d^<-1>). The considerable particle loss rate (13% [100 m]^<-1>) below the mesopelagic layers in a short period suggests the occurrence of consumption processes induced by the sporadic supply of freshly produced particles from above.}, pages = {50--55}, title = {SPORADIC INCREASE OF PARTICLE SEDIMENTATION AT THE ICE EDGE OF THE ANTARCTIC OCEAN DURING THE AUSTRAL SUMMER 1994-1995 (18th Symposium on Polar Biology)}, volume = {10}, year = {1997} }
