Underwater data centers may be coming to the U.S.—smack in the middle of endangered whale habitat

October 27, 2026 — The battle over where to put data centers is heading below the waves: the Trump administration is considering proposals to build two massive underwater data centers off the country’s coast. The sites selected for the projects—one in Cook Inlet, Alaska, and one in the Gulf of Maine—are smack in the middle of two endangered whale populations’ habitats.

Whales are “skittish animals,” says Arial Brewer, a beluga researcher at the University of Washington and the National Oceanic and Atmospheric Administration. “A massive-scale project like this could really stress them out in a lot of different ways.”

Data centers, with their thousands of servers, generate considerable heat that can damage equipment if not offset in some way. Land-based facilities use massive amounts of fresh water to cool down. By putting a data center underwater, the ocean can easily dispel that heat. “Cooling is a large part of what a data center costs to run, and seawater is a free sink,” says Vishal Misra, a computer scientist and professor at Columbia University.

Guam shut out as CNMI seabed mining sale advances in ‘race to the bottom,’ governor’s office says

August 24, 2026 — Guam’s exclusion from the formal comment process on a proposed seabed mining lease sale near the Northern Mariana Islands, paired with pointed new criticism from Gov. Lou Leon Guerrero’s administration, is adding fresh tension to a federal push that critics say is moving faster than anyone can properly weigh the risks.

The Marine Minerals Administration published a proposed leasing notice Monday covering five lease blocks along the edge of the Mariana Trench. Under the notice, only the CNMI governor holds a formal right to submit comments before a final leasing notice can be issued. Guam’s governor has no such standing, even though the waters sit next to the island.

CNMI Del. Kimberlyn King-Hinds said she does not understand the restriction. “I don’t know, and I’m not sure why she would not be since these waters are adjacent to Guam as well,” King-Hinds said in an interview with The Guam Daily Post on Wednesday.

Leon Guerrero’s administration had already raised concerns after the notice came out this week. In a follow-up email Thursday responding to additional Post questions, the administration went further, faulting federal regulators for moving without adequate study.

Governor, Moylan push back on seabed mining plan

August 21, 2026 — The federal government has taken its clearest step yet toward opening the seabed near the Northern Mariana Islands to commercial mineral mining, and Guam’s governor and delegate to Congress are warning Washington not to move faster than the science allows.

The Marine Minerals Administration, formed in July when the Interior Department folded the Bureau of Ocean Energy Management into a new agency, published a proposed leasing notice Monday covering five lease blocks along the edge of the Mariana Trench. The blocks span roughly 67 million acres, an area close to the size of Nevada, and the agency has set Dec. 16 as the proposed date for the sale.

In a statement released Wednesday, Gov. Lou Leon Guerrero’s office acknowledged Washington’s interest in reducing reliance on foreign mineral sources but said caution should come first. “National security cannot mean asking the people of the Pacific to accept environmental risks before those risks are fully understood,” the statement said.

The governor’s office cautioned that permitting exploration now could make it harder to pull back later, once companies have invested money in surveying the seabed. “A lease is not authorization to begin commercial mining, and it is important that we be precise about that. But it is also not an insignificant step,” the statement said, calling on the Interior Department and the new marine minerals agency to consult with residents of the Mariana Islands before going further.
