Phytoplankton, as the base of the oceanic food chain, plays a fundamental role in marine ecosystems. Since the Bohai Sea, the largest inner sea in China, is an important spawning ground and nursery field as well as a feeding ground for marine creatures, it is critical to understand variations of phytoplankton in the area. Chlorophyll a (Chl a) concentration is an important proxy for phytoplankton biomass. Chl a derived from both the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) from 1997 to 2010 and the MODerate resolution Imaging Spectroradiometer (MODIS) sensor on satellite Aqua from 2002 to 2018 were combined into one time series to investigate the spatial and temporal variability of Chl a concentrations in the Bohai Sea using Google Earth Engine. Annual Chl a concentrations increased significantly by 14.1% in the study area over the past two decades. Chl a concentrations in every season and in all months except November have stagnated or increased. Chl a concentrations increased mainly in the middle part of the sea. Sea surface temperature (SST), wind speed and precipitation were also analyzed. Increases in precipitation over the land around the Bohai Sea and wind speed in summer, as well as decrease in SST in autumn, all contributed to the rises of Chl a concentrations. Nutrients from land may play an important role in phytoplankton growth.
