Environmental groups want the Obama administration to designate the Aleutian Islands as a national marine sanctuary.

Public Employees for Environmental Responsibility is spearheading the proposal. The Center for Biological Diversity is among other groups listed in the nomination letter.
Here's a press release discussing the basis for establishing an Aleutian Islands National Marine Sanctuary.
