Alfin has been doing an excellent job of tracking the work that is being done to stop the Gulf Oil Leak. Here is the coverage from most recent to earlier coverage.
Environmental damage from the ongoing oil spill continues to be limited, due to the nature of the hydrocarbon mix, favourable weather and currents in the warm Gulf waters, and a good surface response by air, land, and sea.

Meanwhile, BP engineers retrieved the “brain” of the failed blowout preventer (BOP) and performed “brain surgery” to allow them to get an accurate read on the pressure at the well head. Next, they hope to perform the “top kill” or “junk shot” operation — shoving rubber junk and matting through the BOP in an attempt to clog it, and stop the oil flow. They would then top the plug off with cement. BP had conservatively estimated that it would require 3 months to drill the relief wells, but if they are lucky they may cut that time in half.

The Exxon Valdez oil spill in Alaska’s Prince William Sound released 10.8 million gallons of oil — or almost 250,000 barrels of oil. But natural oil seeps off California release up to 80 times that amount. And natural seeps in the Gulf of Mexico release twice the amount as the Exxon Valdez every year.
