NMFS should deny ION’s application. ION’s proposal is remarkable for both its scope and timing. ION intends to use a survey vessel equipped with a 26-gun array with a total volume of 4,450 cubic inches. Not only is this an incredibly powerful array, but the surveying will take place across a large portion of the Alaskan Beaufort and Chukchi seas, with transect lines of approximately 7,175 kilometers (4,458 miles).
