The early news is certainly not good.
A helicopter crew and pollution investigators have been dispatched to Main Pass Block 41 in response to two calls to the National Response Center, the federal point of contact for reporting oil and chemical spills, said Paul Barnard, an operations controller for Coast Guard Sector New Orleans.
The first caller, around 11 a.m., described a sheen of about a half-mile long and a half-mile wide, he said.
About two hours later, another caller reported a much larger sheen -- about 100 miles long -- originating in the same area and spreading west to Cocodrie on Terrebonne Bay, Barnard said.
