That Oil Slick
I have been following the BP oil spill in the Gulf of Mexico, indeed, as we are looking at marine systems in science it has been an incredible opportunity to bring news into the classroom. Also, our marine systems unit has students look at oil drilling that could happen in the Beaufort Sea area.
Anyway, SkyTruth has been a great site to follow for visuals and assessment on the spill supported by reasons. Just now was disturbing to look at. Cloud cover has hidden a huge part of the spill. I think today's estimate of how much water is covered in oil slick has almost doubled from yesterday as it is a clear day and the oil has been expanding under the cloud cover.
Anyway, have a look at SkyTruth.
