SITKA -- The sheen from a fishing boat that sank northwest of Sitka has grown.
State conservation officials say that the Evening Star has apparently shifted and sank into water 300- to 400-feet deep in Slocum Arm.
The sheen is now about a mile-and-a-half long and 25 feet wide.
About 1,000 feet of containment boom is being deployed to protect streams from the new discharge. Additional boom had been placed around the ship before it shifted.
The ship was believed to have 1,000 gallons of diesel fuel, 25 gallons of lube oil and a hydraulic oil tank with a capacity of 160 gallons on board when it capsized Aug. 2.
Sonar that will arrive in Sitka on Saturday will be used to pinpoint the ship's location.
