Here's a press release from the U.S. Department of Commerce, and Commerce Secretary Gary Locke's letter to Alaska Gov. Sean Parnell.
I've heard that this declaration isn't likely to result in much direct aid to fishermen or other residents in Western Alaska.
"The declaration doesn’t bring any immediate aid, so relief must be sought through a congressional appropriation," the governor's special assistant for fisheries, Cora Campbell, tells me. "We will be working with stakeholders and the delegation to determine what type of relief to request."
