Sunken World War II vessels have begun to corrode and in some cases have started to leak heavy bunker fuel, potentially causing shoreline oiling events. In 2010, NOAA, the Coast Guard and other partners assessed 20,000 wrecks and identified which wrecks were most likely to still contain significant volumes and to pose a potential threat. The outcome of this effort was a database named the Remediation of Underwater Legacy Environmental Threats (RULET), created for response continents planning to identify polluting wrecks that might negatively impact ocean ecology and economy. Utilizing historical evidence, archaeological interpretation and salvage engineering, combined with pollutant modeling, a ranking matrix was made to quantitatively assess ecological and socio-economical risks from potential spills for 87 listed wrecks. Since the initial review in 2013, updated information has been documented on many of these wrecks. These updates include determining wrecks that no longer contain oil, have undergone oil removal actions and/or have been identified as leaking based on satellite imagery analysis or survey observations. This project identifies wrecks with new information, summarizes those reports, and incorporates relevant information to develop an updated risk ranking. For wrecks that have a high risk ranking off the coast of Louisiana, additional fate and transport modeling was conducted using NOAA’s Northern Gulf of America Operational Forecast System [NGOFS2) and General NOAA Operational Modeling Environment (GNOME). NGOFS is a high-resolution coastal ocean model that has been operational since 2022. Using GNOME, the effects of seasonality in shelf currents and river flow are examined with respect to regions potentially impacted by a worst case discharge from this vessel. The results of this study can help better prepare response planners when creating contingency plans to prevent and efficiently respond to a spill.
