MSNBC is running a small gallery of photos of post-Ike destruction, including a shot by The Houston Chronicle showing oil slicks covering floodwaters around High Island, Texas. This is the same area shown in SkyTruth’s mosaic of NOAA aerial photographs, and it was taken on the same day (September 14). It’s pretty clear that this is indeed floating oil. You can follow this particular slick back to multiple sources on our mosaic, or by using Google Earth (look at Mosaic 8 in this KMZ file to see the High Island slicks).
