In July, the US launched the first of three controversial 2026 deep-seabed mining lease sales in the waters of American Samoa, to be finalized in August; the Commonwealth of the Northern Mariana Islands, to be finalized in November; and Alaska, to be finalized in December. Once the lease sales are sold, it is nearly impossible to reverse the sales unless they are purchased back from the federal government.

In Alaska, fishing is not just a sport; it is a critical element of food security for many Alaskans. As the Arctic faces increasing pressure on fish stocks, including but not limited to overfishing, marine pollution, and rising ocean temperatures, the US is now debating issuing deep-sea mining permits in Alaska waters, the use of which could further harm our marine ecosystems affecting everything from phytoplankton to whales.

Proponents of deep-sea mining argue that the minerals extracted from the seabed are critical to strengthening modern supply chains for technological advancement and national security. At this time, the Bureau of Ocean Energy Management (BOEM) is assessing the potential for Alaska’s Outer Continental Shelf (OCS) to mine cobalt, nickel, and rare earth elements.

At Pacific Environment, we are deeply concerned about the permits that BOEM is considering selling. Deep-sea mining isn’t just about sticking a vacuum on the ocean floor to surgically suck up particular minerals. It also involves large-scale exploration and extraction that will further disrupt already fragile ecosystems, creating increased pollution from discarded sediments, sharp increases in noise, and other potential dangers to the marine environment and food security of Arctic Peoples.

The Risks of Deep-Sea Mining in Alaska

Deep-sea mining would deploy mining equipment in some of the deepest and least understood areas of the ocean such as hydrothermal vents and seamounts. The wildlife that inhabit these areas—including plankton, corals, fish, and marine mammals—often exist only in those places and nowhere else on the planet. When damaged, these ecosystems are slow to recover, and the damage is likely to be permanent. Sea mining activities also result in massive sediment plumes that smother marine life on the bottom and in the water column.
