Every summer, biologists visit Alaska to count Steller sea lions. The western stock of the population has been in decline for nearly 40 years — hitting a low in 2002.

A recreational vessel ran aground Wednesday night in Captains Bay, according to Ben Wagner with the U.S. Coast Guard Marine Safety Detachment Unit in Dutch Harbor.

Wagner said the owner was moving the boat to a new location when the tide went out and the vessel ran aground on rocks near the shoreline. No one was injured, but responders did notice a slight oil sheen in the water near the boat.
