We just processed a NASA/MODIS image taken from the Terra satellite this afternoon that shows slicks spread across 2,233 square miles, and within 22 miles of shore. See it here. The image suffers from clouds and haze (a problem we don’t have to deal with on radar images) so we used somewhat more sophisticated spectral processing to identify the oil slicks. And no, it’s not Photoshopped; we applied a modified Gaussian contrast-enhancement algorithm:

MODIS satellite image taken this afternoon, April 27, shows growing oil slick in the Gulf.
Spectrally enhanced version allows easier identification of oil slick on this cloudy / hazy image.
