ANCHORAGE, Alaska (AP) - Divers are expected Tuesday to begin salvage of an 81-foot tug that sank last week near Sitka.
The Powhatan, owned by Samson Tug and Barge, sank Wednesday night while docked at Staffigavan Bay about 7 miles (11 kilometers) north of Sitka.
The tug after it sank shifted downslope 1,083 feet (330 meters), moving from a depth of 49 feet (15 meters) to 197 feet (60 meters).
Samson estimates the tug carried 325 gallons of lube oil and 12 gallons of diesel.
The Alaska Department of Environmental Conservation says divers from Alaska Commercial Divers will try to minimize further release of oil and assess the tug for salvage.
Responders positioned containment and absorbent boom to collect oil emerging under the dock.
The cause of the sinking is under investigation.
