Summary of Field Work: |
Evaluate the impact of the Deepwater Horizon spill on shipwrecks in the Gulf of Mexico. In-situ and ex-situ studies to quantify the relationship between sediment mechanical properties (i.e., critical shear stress, erodibility, liquid limits) and physical and biogeochemical properties (i.e., grain size, water content, structure, organic carbon content, particle surface chemistry, clay mineralogy).
Field work will focus on surveying shipwreck formation processes at sites impacted by the spill and control sites not impacted by the spill. Video transects will document changes in hull degradation and site stability on its associated biodiversity. Water, sediment and shipwreck materials will be recovered to determine the extent of exposure to oil and or dispersants and their impact on the rate of wreck degradation (accelerate or reduce) and wreck associated macro and micro biological communities. Sediment cores will be collected for physical and biogeochemical property analysis (grain size, water content, core logger). The study will provide detailed before-after comparison of pre-spill and post-spill archaeological, physical and biological data collected at several GOM shipwreck sites and surrounding areas and will evaluate temporal changes in spill exposed and non-exposed (control) sites. The study will include metal-hulled shipwrecks from a 2004 study and additional wooden shipwrecks previously investigated by BOEM. This initial effort is intended as the first component of a long-term monitoring study. |
