ANCHORAGE, Alaska (AP) — Alaska’s Prince William Sound will see more, but smaller icebergs in the next decade.
That’s according to a report by a marine safety organization that monitors tankers carrying oil from the trans-Alaska pipeline.
The Prince William Sound Regional Citizens’ Advisory Council says icebergs from Columbia Glacier are smaller because they have to travel farther before reaching shipping lanes.
The glacier since the late 1980s has receded more than 10 miles. Icebergs lose volume in the water from melting and fracturing.
Icebergs remain a serious hazard. The report says smaller icebergs can more easily float over the glacier’s terminal moraine at the head of Columbia Bay.
One tanker, the Overseas Ohio, in 1994 was seriously damaged by an iceberg as it headed north to pick up oil.
