Catch John Amos of SkyTruth (yes that’s me) talking about the Gulf spill, offshore drilling, and satellite images on CNBC at 8pm Eastern tonight. The show is called “America’s Crude Reality” and features SkyTruth’s testimony to Congress last fall warning of the risks posed by offshore drilling; our work on the blowout and 10-week-long spill off Australia last year; and our ongoing investigation and monitoring of the BP / Deepwater Horizon blowout and spill. Dr. Ian MacDonald, the Florida State University oceanographer who helped us calculate that the spill was at least 20 times larger than official estimates at the time, also appears tonight. Check here for show times – don’t miss it!
Two radar satellite images (black and white) taken by the RADARSAT-1 and RADARSAT-2 satellites on June 27, 2010, show oil slicks and sheen extending across 19,112 square miles (49,500 km2) in the Gulf. The radar images were acquired at 6:48 am (long image on right) and 6:52 pm (image on left) local time:
Alex is now causing problems – cleanup operations were suspended today because of the rough weather. Even the radar satellite images are getting messed up by gusty thunderstorms spawned by Alex and sweeping through the area. We may not get any good satellite imagery of the oil spill again until Alex has exited the Gulf later this week.
See all of our satellite images, maps and photos for the ongoing spill in our image gallery.

Large bands of clouds containing strong thunderstorms are moving into the northern Gulf and affecting the area of the leaking Macondo oil well, raising the anxiety level surrounding the cleanup and response operation, but Alex is forecast to move steadily northwest, making landfall around the Texas-Mexico border:
Storm fans: see an animated loop of Alex’s progress.
Oil slick and sheen cover 24,453 square miles on the June 25 image. Slicks appear to impacting beaches from Gulfport, Mississippi to Pensacola, Florida. Freshly upwelling oil is apparent at the site of the leaking Macondo well, and is moving west in the immediate vicinity of the well:
On June 26, a MODIS/Aqua satellite image shows oil slick and sheen covering 23,049 square miles, threatening beaches from Gulfport and Biloxi to Destin, Florida. To the west, the slick extends to Port Fourchon, Louisiana. Emerging oil is continuing to move west from the well site:
Dr. Oscar Garcia-Pineda of Florida State University has been out in the Gulf this week on the research vessel Brooks McCall. He’s collecting samples and observations of the BP oil slick, and will compare results with simultaneous acquisitions of aerial remote sensing overflights being conducted by NASA. We at SkyTruth are also collecting near-simultaneous satellite imagery to assist this effort. We hope to get a better understanding of how well aerial and satellite remote sensing are detecting oil at (or near) the surface.
Oscar sent us a stunning series of photographs taken on June 22 near “Ground Zero” in the Gulf, the site of the leaking Macondo well, showing the cluster of response vessels there, and the collection and burning of oil. You can see them all in SkyTruth’s Deepwater Horizon Blowout gallery (look for the photos with “FSU Sampling Cruise” in the title). Here are a few:
