So this is the "small" leak, as recorded by BP on May 15 and May 16:

Last week, BP released video of the "main" leak which scientists estimated could have been gushing between 25,000 and 80,000 barrels per day. Having this video helps gives us a better idea of what is gushing into the ocean and should server as a reminder that the official estimate of 5,000 barrels per day is a massive underestimate.

To the extent that this represents increased transparency on the part of BP, it's a very small step. At a minimum, on a daily basis they should provide a sampling of video recorded at random times throughout the day from both leak sites to allow independent observers an opportunity to judge what is going on and whether anything has changed. BP will of course dismiss the importance of understanding how much oil is flowing into the Gulf, but the notion that it doesn't matter whether we know what is happening beneath the sea is laughable, or at least it would be if this weren't such a serious matter.
