The approximate true color of the upper ocean waters, estimated from the ocean color measurements collected by the MODerate Resolution Imaging Spectroradiometers aboard NASA's polar orbiting Terra and Aqua satellites. Red, green, and blue channels are combined to represent what your eye would see in the ocean from this vantage point in space. The image, at approximately 1km resolution, uses radiance data at 678nm, 551nm, and 443nm as the red, green, blue channels, respectively.  The composite image is created by superimposing the most recent four passes with the latest pass drawn on top.  These data are made available by the USF Institute for Marine Remote Sensing, http://imars.usf.edu.
