|This is an image of classified Gymnodinium breve
blooms derived from SeaWiFS Data, July 1998. This image
was downloaded from a NOAA
web site. It is an experimental NOAA product.
An empirical, multispectral classification algorithm was used on the satellite ocean color data to detect the blooms. The blooms often color the water reddish-brown, giving the name "red tides" to these bloom events.
