An aerial view of the submerged USS Arizona at Joint Base Pearl Harbor-Hickham, Hawaii, shows the release of oil from the battleship’s corroding hull. (Image Credit: National Park Service) A tank barge that sank amid rough seas on January 24, 1936, in Long Island Sound carried 500,000 gallons of heating oil. To officials at the National Oceanic Atmospheric Administration, the submerged vessel, known as Cities Service Number 4, poses a serious risk of contaminating the tidal estuary should corrosion of the barge structure cause an oil leak. The hull and rivet structure of Cities Service No. 4 is similar to the Navy battleship USS Arizona, now a hallowed tomb for 1,177 men who died when the Japanese bombed Pearl Harbor on December 7, 1941. Oil still trickles from her damaged hull, which makes the vessel an ideal subject for corrosion rate analysis. In February, the National Park Service transferred hull and rivet pieces from the USS Arizona to the U.S. Coast Guard Academy for analysis by team of marine and environmental science majors. Three senior-level cadets are working to find parallels between the USS Arizona’s propensity for corrosion in the Pacific Rim and several wrecked vessels on the northeast ...
