Integrated Methods for Marine Munitions Site Characterization: Technical Approaches and Recent Site Investigations

摘要

Investigation and remediation of munitions and explosives of concern (MEC) at marine sites are both time consuming and expensive. MEC assessment in marine environments has additional challenges compared to terrestrial sites, including the high cost of marine operations, the general absence of surface sweeps prior to geophysical assessments, the difficulty of quick or effective site reconnaissance activities, and high levels of clutter in ports, harbors, and bays. Consequently, a high payoff exists for effective methods of feature extraction and data fusion for improved assessment in marine settings. Recent site investigations have pointed to the potential of utilizing innovative geophysical sensing and new methods that directly link MEC experts to enabling technologies. We present two case studies to highlight the benefits of combining various technologies to provide the information needed for comprehensive munitions site characterization. This approach has been successful for both time-critical response activities and longer-term remedial investigations.
