The US Extended Continental Shelf Task Force, comprised of several agencies including the NOAA, State Department, Department of Energy, and Environmental Protection Agency, is partnering with Canadian agencies to survey the Arctic continental shelf on a 41-day mission that began August 7. The goal of the project is to define the outer limits of the U.S. and Canadian continental shelf, in part to delineate control over mineral resources on the shelf and the rights to construct structures such as wind farm and pipelines.
