Abstract:

The objective of this report was to provide detailed time series measurements of the in situ boundary layer processes responsible for munitions mobility including transport, burial, and excavation. The researchers performed the first of a proposed set of field experiments to characterize the environment in which munitions are found while simultaneously recording the location of munitions relative to the seafloor at high spatial and temporal frequency. Unlike previous investigations that have provided before and after snapshots of munitions mobility, our instrumentation is capable of providing high spatial and temporal resolution measurements of all the relevant boundary layer processes e.g., wave height and direction, current profiles, suspended sediment concentration, and sediment erosion and deposition while simultaneously monitoring the mobility of surrogate munitions.
