In an article published in the journal Remote Sensing, the researchers used Sentinel-2/Multispectral Instrument (MSI) imagery data to a calibrated ocean chlorophyll 2-band (OC-2) model to retrieve chlorophyll-a (chl-a) concentration in the Ha Long bay from 2019 to 2021. Using Sentinel-2 MSI photos on the Google Earth Engine (GEE) platform, this study examines the anthropogenic impact on chlorophyll-a concentration in Ha Long Bay in Ha Long City from 1 January 2019 to 30 June 2021. The method based on the OC-2 band created for Bengal Bay was used in the research and calibrated for the chl-a concentration estimate in Cua Luc Bay. Cua Luc Bay may be subjected to the OC-2 algorithm since both bays have similar topography and climate.
