Over the weekend, BP began working to place a new cap on the gushing Deepwater Horizon well in the Gulf of Mexico. The old cap, estimated to divert 15,000 barrels of oil a day, was removed Saturday, in order to make room for the new one. This has allowed oil from the well to gush unimpeded. If all goes according to plan, the new cap should contain all the oil from the well, an estimated 60,000 to 80,000 barrels of oil a day.
For details on this new plan, we are joined from New Orleans, La., by Henry Fountain, science reporter for The New York Times.
