Tracing floating green algae blooms in the Yellow Sea and the East China using GOCI satellite data and Lagrangian transport simulations

Abstract

To detect the bloom an index based on multi-spectral band ratios using three wavelengths (555, 660, 745 nm)was utilized. One month later, the GOCI images detected widespread floating green algae patches (east&#8211 west elongated) across the Yellow Sea and East China Sea (YS, ECS). The presence of the patches was confirmed from various oceanic observation cruises. Lagrangian particle tracking experiments were conducted to understand the pathway of the floating green algae patches and interpret the physical forcing factors that affect the distribution and advection of the floating green algae.he Yellow Sea and East China Sea (YS, ECS).
