Oil Slick Continues in the Gulf of Mexico

May 30, 2013
On April 20, 2010, a deadly explosion at an offshore oil rig in the Gulf of Mexico damaged a well that was nearly a mile underwater. More than a month later, officials had yet to contain the slick. This image of the Mississippi River Delta and nearshore waters was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite on May 23, 2010. Oil appears light gray, occasionally streaked with brown. The largest oil patch is in the vicinity of the damaged well, but streamers of oil also spread to the northeast. Oil slicks are notoriously hard to see in photo-like satellite images such as this one. A thin sheen of oil against an already dark background is often imperceptible unless viewing conditions place the oil slick in a particular spot of the image: the sunglint region. The slick was not in the sunglint region when this image was captured, and therefore, the slick is not as prominent as it has appeared in other images.
