위성과 Sediment Trap 자료를 이용한 동해 울릉분지의 입자태 유기탄소 플럭스 변화

Abstract

Surface concentrations and vertical fluxes of particulate organic carbon (POC) were measured in the northern Ulleung basin of the East/Japan Sea during November 2010 and August 2014 by using satellite observation and sediment trap experiments. Primary production rates varied from 0.58 to 2.55 g C m-2 day-1 and the vertical total mass fluxes ranged from 0.12 to 1.47 g C m-2 day-1 at 500 m depth, 0.05 to 1.00 g C m-2 day-1 at 1000 m depth and 0.12 to 1.43 g C m-2 day-1 at 2000 m depth, respectively. Based on these results, the ratio of the settling flux of POC to primary production from the euphotic zone to the deep sea is roughly estimated by 13~35%, and about 2.4~9.6% of the primary production was arrived at bottom sediments.ts.
