Authorities say more than 119,000 pounds of oil-soaked sand and debris have been removed from island shorelines tainted by the spill nearly two weeks ago when two vessels collided in the Houston Ship Channel.
Officials representing the U.S. Coast Guard and other agencies say about 465 workers are removing oil from the Texas shoreline.
They were focusing Thursday on a nine-mile stretch of Matagorda Island along the Gulf of Mexico. But workers also are concentrating to the south on Mustang Island and Padre Island.
Crews also have recovered dozens of dead birds along with the carcasses of two dolphins and two freshwater turtles.
A ship punctured an oil barge March 22 near Texas City. The oil stream extended into the Gulf of Mexico and then southward along the Texas coast.
