Short Term Variability of Particle Fluxes and Its Relation to Variability in Sea Surface Temperature and Chlorophyll a Field Detected by Ocean Color and Temperature Scanner (OCTS) off Sanriku, Northwestern North Pacific in the Spring of 1997

摘要

A sediment trap experiment was carried out in conjunction with an over flight of Ocean Color Temperature Scanner (OCTS) on board Advanced Earth Observing Satellite (ADEOS) at 40°E, 143°E off Sanriku in April to May 1997. Short term variability of particle fluxes was examined at depths of 450 m and 600 m from April 6 to May 1 with a sampling interval of two days, and at 450 m with one day interval from 2nd to 10th May. Daily averaged mass flux at 450 m and 600 m was 815 mg m~-2d~-1 and 862 mg m~-2d~-1, respectively. A sharp increase in mass flux was observed during the period from April 26 to April 29 with the highest mass flux of 8 g m~-2d~-1.
