Would be great to add a chlorophyll concentration layer. Chlorophyll concentration maps display the quantity of plankton and other plant life in the surface layer of the ocean. Showing 1-day 2-day, 3-day+ composite layers is valuable information to fishermen. Several services are already offering this for a fee, i.e. Terrafin, Satfish and others.
@trudenko Good point, we could consider it if there is a sufficient source for data.
