GALVESTON, Texas (AP) — As workers in bright yellow suits picked quarter-sized “tar balls” out of the sand along Galveston Bay on Monday, strong incoming tides kept washing more ashore.

Elsewhere, crews lined up miles of oil booms to keep oil away from the shoreline and bird habitats, two days after a collision in the Houston Ship Channel dumped as many as 170,000 gallons of oil from a barge into the water along the Gulf Coast and shut down one of the nation’s busiest seaports.
