The Healy and crew are preparing for a ceremony commemorating a fatal dive accident in 2006, in which two crew members lost their lives while on a diving mission in the Arctic. The U.S. Coast Guard Cutter Healy (WAGB 20) is designed to conduct a wide range of research activities, providing more than 4,200 square feet of scientific laboratory space, numerous electronic sensor systems, oceanographic winches, and accommodations for up to 50 scientists.
