In the marine environment, chlorophyll-a (Chl-a) is a key variable for ocean color. Considering the environmental variables related to the growth and distribution of marine phytoplankton, a convolutional neural network (CNN) called OCNET was developed for reconstructing Chl-a concentration data in open sea areas.
