Underwater Video Surveys

For over 20 years, CR has used underwater surveys to support monitoring programs; eelgrass, epifauna, habitat and substrate mapping; sand resource studies for beach nourishment; and marine engineering projects at wind turbine landing sites, outfalls, pipelines, cable routes, and dredged material disposal sites surveys.

CR personnel are experienced in marine macrofauna identifications and underwater video substrate and biotic classification using the Coastal and Marine Ecological Classification System (CMECS).
