Basic descriptions
The Global Coastal Algal Bloom Dataset is derived from daily MODIS satellite images with a resolution of 1 km, totaling 0.76 million images globally, spanning the period from 2003 to 2020. It captures the occurrences of coastal blooms for 126 out of 153 ocean-bordering countries worldwide. Compared to prior global coastal phytoplankton datasets like HAEDAT and NASA’s chlorophyll a standard product, this dataset presents a more compelling trend in phytoplankton occurrence. Users can utilize this dataset to explore the spatiotemporal distribution characteristics of global coastal phytoplankton from 2003 to 2020. Moreover, it enables users to obtain bloom data for a specific research area, facilitating targeted studies.
