Via The Map Room: NASA has produced a time-lapse video of the expanding Gulf of Mexico oil slick.
This short video reveals a space-based view of the burning oil rig and, later, the ensuing oil spill through May 24. The timelapse uses imagery from the MODIS instrument, on board NASA’s Terra and Aqua satellites. The oil slick appears grayish-beige in the image and changes due to changing weather, currents, and use of oil dispersing chemicals.
