CLOTILDA DIVER ASSESSMENT, ARTIFACT EXTRATION & INVESTIG

Specifications include, but are not limited to: 1. A high-resolution sonar survey of the interior of the exposed structure at 1BA704. The detailed imagery will informassessment of risk to the site from the effects of ongoing erosion and other natural processes. The data will be usedto develop a scientific, evidence-based plan to address and arrest effects of ongoing erosion and other natural processes,help to determine if stabilization of the site is necessary, and provide information to inform a preservation plan.2. A marine geological study of 1BA704 that assesses the composition, structure, and resistance of the sediment in andaround the wreck and an engineering assessment to determine both the stability of the site in its current context andthe feasibility of any proposals to address stability problems if identified, such as a cofferdam or other structure thatmay be needed to protect the wreck. The area around the wreck will also be investigated to evaluate the riverbed inconsideration of erecting a monument on the site.3. Installation, operation, and management of a system to measure and monitor river current and water movement bothin and around the wreck to further assess the degree of risk to the site from the effects of ongoing erosion.4. A biological assessment of the benthic zone to identify the species that have colonized 1BA704, from bacteriathrough larger flora and fauna and to determine the degree to which the biological colonization of the wreck is causingdecay.5. A structural assessment of the hull by engineers to determine if the port side of the wreck, nearest the edge of thelandform, needs support to preserve its integrity such as a cofferdam or other structure that may be needed toprotect the wreck.6. Targeted artifact excavation to recover any diagnostic artifacts and/or exhibit quality artifacts with industrial diveefforts, conservation, and stabilization plans for any artifacts recovered.7. Collection of wood samples from the decking, and frames inside the wreck and from areas currently buried toassess condition, level of deterioration, DNA sampling, and to inform a scientific, evidence-based plan to conserve andpreserve 1BA704.
