Coast Guard Petty Officer 1st Class David Bradbury waits for his dive partner to enter the water from a Coast Guard Cutter Healy small boat during a cold water ice dive in the Arctic, July 30, 2017. Divers are the Coast Guard’s primary resource for the service’s subsurface capabilities and perform a full spectrum of Coast Guard missions; including underwater inspections and maintenance on icebreakers and other cutters, surveying critically endangered species habitats and providing underwater searching capabilities for search and rescue operations.
