USS Arizona Short-Term Mass Loss Studies

Summary

This is an abstract from the session entitled "Hard Science on Hard Steel: Scientific Studies of the USS Arizona" , at the 2020 annual meeting of the Society for Historical Archaeology.

Corrosion rates for the USS Arizona, based on seventy-eight years of exposure in Pearl Harbor, are used by the National Park Service to assess the current and future state of this ship. To support ongoing efforts to improve corrosion models, short-term mass loss studies have been undertaken by cadets at the U.S. Coast Guard Academy in partnership with the NPS Submerged Resources Center and Pearl Harbor National Memorial. This work reveals how corrosion rates change at this site in the first three years, providing empirical data for the NPS early exposure Secant Corrosion Rate correlation model. Placement of C1010 steel coupons at four locations and subsequent analysis provide a baseline reference. Launched in August 2018, this investigation additionally serves to assess and manage actively and potentially-polluting shipwrecks resting in U.S. waters.
