VRHabilis (VRH) was awarded a subcontract to support a Remedial Investigation/Feasibility Study (RI/FS) of potential UXO, at the former Cape Pogue Little Neck Bomb Target, the former Moving Target Gun Range at South Beach and the Tisbury Great Pond. Over the one year life of this project, VRH was tasked with re-acquiring geophysical anomalies off shore in 30-60 feet of seawater using GPS technology. Using the VRH patented HeckHousing™ for underwater magnetometers, these geophysical anomalies, selected by the project Geophysicist, were then investigated by divers using surface supplied or “Deep Sea” diving equipment. Many of the anomalies lay under the sand on the sea floor and equipment such as an airlift vacuum or a jet pump were needed to excavate the anomalies sufficiently for the diver and topside personnel to make a determination as to what the target anomaly was through the custom designed cameras on the diver’s helmet.
Conducting surface supplied dives from both boat and shore based stations, VRH dive teams detected, located and recovered subsurface contacts for characterization and disposal, resulting in recovering over 150 pieces of cultural debris and 114 pieces of MEC/MPPEH (Munitions and Explosives of Concern/Material Potentially Presenting an Explosive Hazard).
