Underwater Remote Sensing
Underwater imagery is useful in stand-alone surveys or in conjunction with data acquired by direct sampling. Versar scientists have collected underwater data using remote sensing technologies such as video imagery, still photography, and acoustic sensors. We are experienced with a variety of interpretation and analysis techniques from applying advanced classification algorithms to collecting point-count statistics to performing basic photo interpretation. Using sophisticated remote sensing techniques, Versar has achieved a variety of otherwise difficult objectives for our clients, including characterizing biological resources; mapping underwater debris fields; stratifying benthic habitats; and quantifying biofouling and non-indigenous species on ship hulls.
Habitat Characterization – Underwater video study of benthic conditions for Dare Country, North Carolina.
Sand Borrow Sites – Characterized candidate source areas for sand mining for USACE.
Derelict Crap Traps – Identified lost crab traps in Chesapeake Bay for the State of Maryland.
Benthic Resources – Stratification for NPS biological resource studies at Assateague Island National Seashore.
Ship Hull Biofouling – Performed a photographic study of the underwater surfaces of vessels for the US Maritime Administration.
