Ocean Colour Radiometry
Ocean colour radiometry is a technology, and a discipline of research, concerning the study of the interaction between the visible electromagnetic radiation coming from the sun and aquatic environments. In general, the term is used in the context of remote-sensing observations, often made from Earth-orbiting satellites. Using sensitive radiometers, such as those on-board satellite platforms, one can measure carefully the wide array of colors emerging out of the ocean. These measurements can be used to infer important information such as phytoplankton biomass or concentrations of other living and non-living material that modify the characteristics of the incoming radiation. Monitoring the spatial and temporal variability of algal blooms from satellite, over large marine regions up to the scale of the global ocean, has been instrumental in characterizing variability of marine ecosystems and is a key tool for research into how marine ecosystems respond to climate change and anthropogenic perturbations.

Famous quotes containing the words ocean and/or colour:
“A village seems thus, where its able-bodied men are all plowing the ocean together, as a common field. In North Truro the women and girls may sit at their doors, and see where their husbands and brothers are harvesting their mackerel fifteen or twenty miles off, on the sea, with hundreds of white harvest wagons, just as in the country the farmers’ wives sometimes see their husbands working in a distant hillside field. But the sound of no dinner-horn can reach the fisher’s ear.”
—Henry David Thoreau (1817–1862)
“No one knows the colour of a flower
till it is broken.”
—Hilda Doolittle (1886–1961)
