Definitions:

Primary Productivity

The amount of light energy converted to organic compounds by autotrophs in an ecosystem over a given period. Compare with secondary productivity. See gross primary productivity (GPP) and net primary productivity (NPP).

Ecosystem

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system.

Algal Beds

Large, dense groups of algae that grow together on the seabed or on other surfaces underwater.

Ocean Surface Circulation

The large-scale movement of waters in the ocean surface, driven by wind, coriolis effect, and differences in water density.
