The War Beneath the Waves: Mary Sears and the Navy’s Oceanographic Unit
During World War II, navigating the Pacific Ocean’s perilous tides and currents posed a constant challenge to the U.S. Navy. To update their maps and intelligence, the Navy established an Oceanographic Unit in 1943. The team of scientists was led by Mary Sears, a marine biologist commissioned as a lieutenant junior grade in the women’s division of the Naval Reserve, the WAVES.
