UXO Markout
In the United States alone there are over 200,000 submerged acres suspected of containing Unexploded Ordnance (UXO) and Munitions and Explosives of Concern (MEC). These areas are in shallow water zones such as wetlands, freshwater ponds and lakes, estuaries, rivers, coastal bays, tidal flats, ocean shores and coral reefs. As many of the nation’s military bases are closing and being turned over to civilian use, there is a mandate for these areas to be geophysically surveyed to reveal any concealed hazards. Electromagnetic (EM) detectors are most commonly used to survey these areas and locate any possible UXO/MEC.
Aqua Survey is staffed with Scientists and Marine Professionals
Aqua Survey utilizes its vast array of geophysical instruments and our fleet of vessels to support the detection, characterization and precision mapping of cultural resources. Cultural resources studies are performed to locate and identify submerged artifacts, to investigate circumstances causing the resources to be submerged, to locate resources that need to be avoided during construction and to assist not-for-profit and for-profit marine archaeologists. The following services are provided to support these studies:
• Geophysical studies with side scan sonar, sub-bottom profiling, magnetometer studies, electromagnetic detection studies and bathymetric surveys
• Sediment vibracoring for C14 and grain size analysis
• Electromagnetic detection of buried metallic artifacts with benthic sled and diver maneuvered systems
Aqua Survey Fulfills Your Underwater Markout Needs
Aqua Survey owns and operates survey grade, submersible, high-powered electromagnetic (EM) detection systems that can be rafted, sled-mounted or advanced into sediments using a core barrel into the bottom of ponds, rivers and seas. Large areas can be surveyed by towing a rafted system on a water body’s surface or on a sled along the bottom. With the use of an EM detector contained in the nosecone of a vibracoring barrel (Smart-core), small areas of sediment can be characterized for the presence of deeply embedded metal artifacts. EM is used to map submerged and embedded UXO and MEC, metallic cultural resources, utility markout and treasure. Targets acquired can be accurately geopositioned to facilitate their reacquisition.
The following services are provided for markout:
•Electromagnetic time domain detection systems (towed benthic sled, diver maneuvered system, float system and Smart-core vibracoring system).
• Sub-bottom sonar survey
• Magnetometer and gradiometer survey
• Side scan sonar survey
