U.S. Coast Guard Petty Officer 2nd Class Liam Martens, Petty Officer 2nd Class Cory Smith, two divers assigned to Coast Guard Regional Dive Locker Pacific in Honolulu, Hawaii, conduct a chain swap on a channel marker buoy below the surface in Honolulu Harbor, Hawaii Sep. 26, 2025. Coast Guard divers often support the Coast Guard Cutter Juniper's crew with subsurface maintenance, including chain replacements, which are required due to normal wear from prolonged saltwater exposure.
