Underwater Video Surveys

CR Environmental, Inc. performs underwater video surveys in support of biological monitoring programs, eel grass surveys, habitat and substrate mapping, engineering studies, archaeological surveys, and underwater target identification. CR owns and maintains several video systems, ranging from small 12VDC powered cameras and digital video recorders for use in less than 1 meter of water to a video sled with high-powered LED lights, laser scaling system, armored cable, and oceanographic slipring for use in 100+ meters of water. Our video grab system was custom-built to allow visual confirmation of precise sample locations, particularly important when sampling disposal mounds or in man-made channels.

CR's video survey methodology has been successfully applied to pipeline and cable route planning studies, including cable route planning under the new Massachusetts Ocean Management Plan. GPS coordinate overlays, laser scaling, and 1080p HD video capabilities can be added to any of the platforms as needed.
