This is from Skytruth:
New images from NASA's Terra and Aqua satellites keep coming in. At 8:45 am local time, the Terra satellite passed overhead and captured this image, showing oil slicks and sheen throughout a 9,870 square mile area (=7,455 square nautical miles). Part of the slick appears to be in contact with Cartier Island, a national marine reserve.
Five hours later the Aqua satellite took this image. The wind speed had increased from 10 knots to 18 knots, creating a much rougher sea surface and breaking up or obscuring the thinner slicks and sheen. Only thicker portions of the slick are apparent in this image, adjacent to the Montara platform, covering about 3,940 square miles (=2,976 nautical square miles). No slicks are apparent near Cartier - a good sign on Day 34 of this continuing spill. See all our satellite and aerial images of the spill here.
