Radiation from the ocean surface of light in the visible wavelengths gives
information about the color of the ocean. This "ocean color" (radiances) can
be used to estimate chlorophyll concentration (the pigment in plants and
phytoplankton responsible for photosynthesis and the dominant source of color
in the open ocean) or the coefficients of light attenuation through the water
column and other parameters (generally related to biological processes). In
coastal areas, other biological compounds and minerals add complexity to
interpretation. Clouds will block remotely sensed OC.
