In shallow waters, both benthic and planktonic algae are significant, but over deeper waters and throughout the open oceans, only the phytoplankton contributes, apart from the drifting masses of sargassum weed that occur in some areas of the ocean among the algae, both benthic and planktonic, the variety is considerable.

Despite the large amount of research on phytoplankton, macroalgae have received less attention despite them being, on a per-area basis, one of the most productive ecosystems on earth furthermore, there has been a tendency of studies to measure primary production in single thalli, or monospecific stands. For example, in bb the phytoplankton has the largest biomass, followed by the sea ice algae and the benthic algae but because of higher irradiances in the ice, this component contributes the most to productivity. A device has been developed that allows measurement of the photosynthetic oxygen production of macroalgae or phytoplankton above and in the water column under solar irradiation.
