Critics warn that opening up Arctic waters to mineral extraction could devastate large fisheries and sensitive habitats off Alaska’s shores.

The Trump administration is considering allowing deep-sea mining in the waters off the coast of Alaska, sparking concerns about the fate of world class fisheries and fragile ecosystems.

The Bureau of Ocean Energy and Management, or BOEM, will begin gauging interest in a competitive mineral lease sale on Alaska’s outer continental shelf when a notice is published in the Federal Register on Thursday. The agency, according to a map posted online, is looking at large swaths of the Bering Sea, including the Aleutian Islands.

BOEM’s acting Director Matt Giacona said in a statement that Alaska’s offshore “holds strategic potential for the minerals that drive American industry, defense and next-generation technologies,” and that the request for information is “a practical first step to gauge interest and identify areas where development could make sense for jobs, investment and national supply chains.”

The Trump administration in recent months has moved to unleash more deep-sea exploration and extraction of minerals in U.S. and international waters. BOEM has also made moves to advance deep-sea mining offshore American Samoa, the Northern Mariana Islands and Virginia.
