US Coast Guard joins in Arctic oil rush

The US Coast Guard icebreaker Healy and a group of 20 scientists have embarked on a four-week cruise that will help shape the future of US efforts to claim its share of mineral and oil wealth beneath the Arctic Ocean.

The cruise, which left Barrow, Alaska, on Friday, is the fourth voyage in the last four years to the Chukchi Cap, north of the Bering Strait. The cap is part of a plateau and ridge complex that juts like a thumb from the Alaskan and Siberian continental shelves into one of the Arctic Ocean’s deep basins.
Measurements taken on this cruise are of keen scientific and geopolitical interest.

“Mapping is the fundamental first step in any sort of exploration,” notes Larry Mayer, the chief scientist for the cruise and a researcher at the Joint Hydrographic Center at the University of New Hampshire in Durham. “Like Lewis and Clark, we’re providing a geospatial framework for everything else we need to know” about the least understood ocean on the planet.

But the maps Lewis and Clark generated also provided a foundation for political and economic expansion into the regions they explored. And for the US government, which is underwriting the cruise, that is a headline reason for conducting the survey. The National Oceanic and Atmospheric Administration has been conducting similar surveys over the past several years around the Marianas Islands, the Gulfs of Alaska and Mexico, and off New England, notes Capt. Steven Barnum, who heads the agency’s Office of Coastal Survey.

But the Arctic Ocean has been receiving particular attention because it lacks the detailed undersea maps that other areas enjoy. The maps are aimed at specific aspects of the cap that serve as geophysical baselines the US could use to press future claims to extend its jurisdiction off Alaska beyond the 200-mile limit.

If the US does eventually press such claims it will be a latecomer to an already fractious club meeting.
