BEAFORT SEA (August 11, 2023) A military diver swims behind the icebreaker USCGC Healy (WAGB 20) during a scientific mission in the Beaufort Sea with USCG divers of Regional Dive Locker West and Navy divers of Mobile Dive and Salvage Unit (MDSU) 1 Aug. 11, 2023. Together, the Coast Guard and Navy conducted 42 military dives, totaling 656 minutes of bottom time to depths of 40 feet in the Arctic Ocean. As a component of Explosive Ordnance Disposal Group One, MDSU-1 provides ready, expeditionary, rapidly deployable mobile diving and salvage companies to conduct harbor and waterway clearance, salvage, underwater search and recovery, and underwater emergency repairs in any environment.

The Navy Leagues online magazine, “Seapower,” reports Navy divers have deployed with USCGC Healy, now in the Beuford Sea. There was this interesting note,

“They [the Coast Guard] don’t have a decompression chamber, but they’re getting one,” said Hanson. “We let them use ours for this mission conducted for the Office of Naval Research (ONR), and we helped train the Coastguardsmen divers on the operation, maintenance and transport of a decompression chamber.”

and this nice quote,

“We’re trained to call the Coast Guard if a diver gets in trouble,” Hanson said. “But in this case, we were diving right off the side of a Coast Guard cutter, so we might have been in a super remote place, but the exact people we count on for help were right there.”

The description of diving under the ice is surprising.
