Color Satellite Observation of Borneo Red Tide
What is Ocean Color?
The "color" of the ocean is
determined by the interactions of incident light with substances or particles
present in the water. The most significant constituents are free-floating
photosynthetic organisms (phytoplankton) and inorganic particulates.
Phytoplankton contains chlorophyll, which absorbs light at blue and red
wavelengths and transmits in the green. Particulate matter can reflect and
absorb light, which reduces the clarity (light transmission) of the water.
Substances dissolved in water can also affect its color.
The phrase "ocean color data"
refers to accurate measurements of light intensity at visible wavelengths. As
ocean color data is related to the presence of the constituents described
above, it may therefore be used to calculate the concentrations of material in
surface ocean waters and the level of biological activity. Ocean color
observations made from Earth orbit allow an oceanographic viewpoint that is
impossible from ship or shore -- a global picture of biological activity in the
world's oceans
