attribute	NC_GLOBAL	summary	String	Since 1992, the Southwest Fisheries Science Center's Habitat and Groundfish Ecology team has conducted visual surveys using submersible vehicles to quantify demersal fish communities in deep seafloor habitats that are typically inaccessible to bottom trawls. Data are collected from strip transects recorded with video and still cameras. To date, this georeferenced dataset contains 460,000 individual fishes and 201 taxa, including 242,000 rockfishes (genus Sebastes) comprising 55 species, recorded from more than 2,000 transects at depths 25-1,200 meters, primarily off California. Other data include estimated fish total lengths, habitat, and in situ depth and temperature. The data have applications for a variety of research topics, including ecology, distribution modeling, essential fish habitat, and stock assessment. Videos from the surveys are available for download in mp4 format and searchable by location, depth, species observed, and other factors. This project was born out of a need to collect habitat-specific information on rockfish abundance and ecology that cannot be obtained by traditional survey methods, such as bottom trawling.
