Abstract

Abstract: Understanding biogeochemical processes associated with oceanic eddies is important, and ocean-color remote sensing has been used as a tool to provide large-scale data for such studies. Based on the latest regional bio-optical inversion algorithm in the South China Sea, we used Moderate Resolution Imaging Spectroradiometer (MODIS) to track and monitor a cold eddy originated in the late winter around the Luzon Strait. In the early stage, the eddy carrying high nutritional and high biomass seawater moved toward northwest. Then, the eddy stayed in an area for a month. During this period, with the continuous suction of the eddy, the concentration of chlorophyll-a (Chl-a) increased from 0.26 to 0.33 mg•m^-3 in the eddy area and decreased from 0.24 to 0.15 mg•m^-3 outside the eddy. The concentration of particulate organic carbon (POC), phytoplankton absorption coefficient (a_ph(443)), diffuse attenuation coefficient (K_d(490)) and colored dissolved organic matter (CDOM) showed the same variation trend with Chl-a, while the POC∶Chl-a ratio and fraction of picoplankton (F_p) exhibited opposite trends. When the eddy moved westward, Chl-a, POC, a_ph(443) and K_d(490) decreased slowly because of the weakening of eddy intensity and nutrient supply. Our results demonstrated that the special bio-optical response induced by eddy pumping and advection can be an additional tool to track and study oceanic eddies.

Key words: mesoscale eddy, ocean-color remote sensing, bio-optical algorithm, the South China Sea
