Physical, environmental, and substrate observations were derived from underwater video collected by the Monterey Bay Aquarium Research Institute (MBARI) using remotely operated vehicles (ROVs) offshore of Morro Bay, California. A majority of the data were acquired during three separate surveys in 2019 in support of the U.S. Geological Survey (USGS)/Bureau of Ocean Energy Management (BOEM) California Deepwater Investigations and Groundtruthing I (Cal DIG I) project. Additional observations from underwater video data collected by the Ocean Exploration Trust's E/V Nautilus in 2020 are also included. Slope, rugosity, and depth information derived from multibeam echosounder (MBES) bathymetry data, and induration (an indication of substrate hardness) information, are also included in the point data. A joint USGS-BOEM-MBARI cruise, which took place from 19-26 September 2019 on the R/V Bold Horizon (USGS field activity 2019-642-FA), focused on conducting biological surveys using MBARI's MiniROV (dives M137-148). Additional surveys were conducted from 02-14 February 2019 (dives D1120-1131) and from 01-11 November 2019 (dives D1202-1217) using MBARI's R/V Western Flyer and ROV Doc Ricketts. The ROV-video surveys were designed and conducted to collect video ground-truth information about substrate and biota. MBARI-acquired video was analyzed by MBARI. Analysis of Nautilus video data was done by the USGS.

Transect information developed to analyze the data for biotopes (as described in Kuhnz and others, 2021) and the resulting biotope numbers are included in the point data.

This part of USGS Data Series 935 (Cochrane, 2014) presents observations from underwater video collected in the Offshore of Seattle, California, map area, a part of the Southern Salish Sea Habitat Map Series. To validate the interpretations of multibeam sonar data and turn it into geologically and biologically useful information, the U.S. Geological Survey (USGS) towed a camera sled over specific locations throughout the Seattle map area to collect video and photographic data that would “ground truth” the seafloor. The ground-truth survey conducted in the Offshore of Seattle map area occurred in 2011 on the R/V Karluk (USGS field activity K0111PS) and on the Washington State Department of Fish and Game R/V Molluscan (USGS field activity M0111PS). The underwater camera sled was towed 1 to 2 m above the seafloor at speeds of between 1 and 2 nautical miles/hour. The surveys for this map area include approximately 6 hours (9.1 trackline km) of video.

Seafloor character, a combination of seafloor induration (surface hardness) and rugosity, was derived from multibeam echosounder (MBES) and annotated underwater video data collected offshore of Point Estero, California. The MBES and underwater video data were collected in support of the U.S. Geological Survey (USGS) California Seafloor Mapping Program, under a collaboration with the California State University Monterey Bay Seafloor Mapping Lab, the California Ocean Protection Council, and the National Oceanic and Atmospheric Administration (NOAA). Substrate observations from the underwater video were translated into Coastal and Marine Ecological Classification Standard (CMECS; Federal Geographic Data Committee, 2012) induration classes to use as training for a supervised numerical classification of the MBES data. The seafloor character raster is provided as a 2-meter resolution GeoTIFF.
