Starch in the Oceans
Starch observed in arctic waters of Canada, in the Baltic and Mediterranean seas, in the North Atlantic and Indian oceans, and in the waters about Bermuda, the Virgin Islands, and Jamaica is formed mostly in Gymnodinioideae, benthic algae, and higher aquatic plants and rarely in planktonic Chlorophy...
