| Summary: | January, a sporadic flux increase within a few days in terms of total dry weight of 774 mg m 2 d 1 at 537 m was observed. 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 l (mean 243 m d l). The considerable particle loss rate (13 % [I00 m] ' ) 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. 1. |
