This 1-ton mass of tarball material sums up the enormity of the task of cleaning up the Gulf of Mexico. The giant blob was presented on June 11 by the crew of the Sailfish, a Vessels of Opportunity boat contracted by BP to assist in the largest oil spill response in U.S. history. Lisa Novak, a civilian employee of the Coast Guard, clarified on Monday that the tarball was not found intact, as initially believed. It is an aggregation of material. A press release from the Deepwater Horizon Unified Command, Innovation Improves Tar Ball Removal Capability, describes the process.
