Oil Slick in the Gulf of Mexico


acquired May 24, 2010
www.earthobservatory.nasa.gov/

Sunlight illuminated the lingering oil slick off the Mississippi Delta on May 24, 2010. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image the same day.

Oil smoothes the ocean surface, making the Sun’s reflection brighter in some places, and reducing the scattering of sunlight in other places. As a result, the oil slick is brighter than the surrounding water in some places (image center) and darker than the surrounding water in others (image lower right). The tip of the Mississippi Delta is surrounded by muddy water that appears light tan. Bright white ribbons of oil streak across this sediment-laden water.
