A NASA MODIS Natural-color Oil Slick Image from July 28, 2010

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA’s Aqua satellite captured this natural-color image on July 28, 2010. Around the location of the oil leak, and around the Mississippi Delta, relatively light swirls and patches appear on the ocean surface. These areas might be oil slicks, although other factors could affect the water’s ability to reflect sunlight, especially near the shore. If these pale-hued sheens are oil-slicked areas, they contain very little recoverable oil, according to NOAA.
