USS Arizona, a steel-hulled battleship sunk in Pearl Harbor, HI on 7 December 1941, is an iconic American shipwreck, a war grave and memorial, and is among many shipwreck sites that contain large amounts of potential marine pollutants. Unlike most similar sites, however, USS Arizona has been the subject of long-term and ongoing corrosion studies aimed at understanding and modeling the nature of structural changes to the hull. Gaining a detailed understanding of the interaction between the marine...

In early 2008, twenty-eight archaeological iron and copper alloy artifacts belonging to the Andrews Air Force Base collections curated at the Maryland Archaeological Conservation Laboratory (MAC Lab) were identified as requiring conservation treatment by MAC Lab Federal Collections Curator, Sara Rivers Cofield. The conservation treatment was carried out by Cultural Preservation and Restoration, Inc. (CPR) between November 2008 and February 2009 under U.S. Air Force contract FA4416-08-P-0096....

In 2003, an experimental corrosion platform was placed at the bow of the German submarine, U-166. This platform incorporated fifteen coupons including high carbon, low carbon steel, aluminum, and copper along with oak and mahogany wood coupons. This platform was recovered in 2014 and evaluated for microbiologically influenced corrosion. During the eleven years of deep ocean placement, the oak coupons degraded in four to six years while the mahogany disappeared after ten years. Biomass was...

The project's primary focus was to acquire requisite data for understanding and characterizing the complex corrosion and deterioration processes affecting Arizona's hull. The information was then fed into a model to predict the nature and rate of structural changes resulting from corrosion in order to inform management actions.

Microbiomes associated with wooden and steel shipwrecks were investigated using next generation sequencing.  Samples were derived from in situ biofilm monitoring platforms deployed for ~4 months, and sediment collected ~2-5 m from shipwrecks.  The goal of the investigation is to determine rates of recruitment and community structure at sites located within and outside of areas impacted by the Deepwater Horizon spill (DWHS). Sediments will elucidate the influence of shipwrecks on the geochemistry...

This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology. Aircraft were a major component of the U.S. war effort in World War II, and today numerous examples can be found throughout the waters of the Asia-Pacific region. Due to their cultural and historical significance to modern stakeholders, understanding the decay trajectories has become an important issue in the realm of cultural heritage management, especially...

This is an abstract from the session entitled "Methods for Monitoring Heritage at Risk Sites in a Rapidly Changing Environment", at the 2023 annual meeting of the Society for Historical Archaeology. Archaeologists have increasingly examined the natural forces that threaten submerged cultural heritage resources. For metallic sites, such as sunken steamships and aircraft, corrosion has garnered a considerable amount of this interest. While general corrosion resulting from exposure to seawater...

Consolidated iron corrosion products (rusticles, tubercles and flakes) were collected from historic shipwrecks in the Gulf of Mexico before (2004) and after (2014) the Deepwater Horizon oil spill (2010). In all cases the iron corrosion products were stratified. Goethite and lepidocrocite were identified by powder X-ray diffraction in samples before and after the spill. The internal structure of samples collected before the spill has been examined in detail with environmental scanning electron...

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...
