Abstract

Subsurface chlorophyll-a (chl-a) concentration variability on Sumatera’s Northwestern coast is part of the phytoplankton biomassthat supports and enriches the region’s fisheries supplies. During the 2017 northeast monsoon season from 25thNovember 25 to 11thDecember, the Ekspedisi Widya Nusantara (E-WIN) collected data from 16 stations. The finding demonstrates a rise in subsurfacechl-a concentration as you get closer to the coast. Furthermore, the deep chl-a maximum (DCM) is only found offshore, with depthsbetween 30 to 50 m and chl-a concentrations of 0.07 to 0.25 mg.m−3. Surface chl-a concentrations near the coast were found tobe high, ranging from 0.2 to 0.25 mg.m−3
