This part of DS 781 presents video observations from cruise F208NC in northern California. The vector data file is included in "f208nc_video_observations.zip," which is accessible from https://pubs.usgs.gov/ds/781/video_observations/data_catalog_video_observations.html.
Video observations from cruise F208NC will be published in four future Scientific Investigations Maps in the California State Waters Map Series (namely, Offshore of Elk, Offshore of Point Arena, Offshore of Fish Rock, Offshore of Gualala, Offshore of Salt Point, Offshore of Fort Ross, Offshore of Offshore of Bodega Head, Offshore Tomales Point, Offshore of Point Reyes, Drakes Bay and Vicinity, and Offshore of Bolinas map areas).
Between 2006 and 2007, the seafloor in the Offshore of Offshore of Elk, Offshore of Point Arena, Offshore of Fish Rock, Offshore of Gualala, Offshore of Salt Point, Offshore of Fort Ross, Offshore of Offshore of Bodega Head, Offshore Tomales Point, Offshore of Point Reyes, Drakes Bay and Vicinity, and Offshore of Bolinas map areas map areas in central California was mapped by California State University, Monterey Bay, Seafloor Mapping Lab (CSUMB) and by the U.S. Geological Survey (USGS), using both multibeam echosounders and bathymetric sidescan sonar units. These mapping missions combined to collect bathymetry and acoustic-backscatter data from about the 10-m isobath to out beyond the 3-nautical-mile limit of California's State Waters. To validate the interpretations of sonar data in order to turn it into geologically and biologically useful information, the USGS ground-truth surveyed the data by towing camera sleds over specific locations throughout the region. During the 2008 ground-truth cruise, the camera sled housed two video cameras (one forward looking and the other vertical looking), a high-definition video camera, and an 8-megapixel digital still camera. The video was fed in real time to the research vessel, where USGS and NOAA scientists recorded both the geologic and biologic character of the seafloor into programmable keypads once every minute. In addition to recording the seafloor characteristics, a digital still photograph was captured once every 30 seconds. This ArcGIS shape file includes the position of the camera, the time each observation was started, and the visual observations of geologic and biologic habitat.
These data are intended for science researchers, students, policy makers, and the general public.
The data can be used with geographic information systems (GIS) software to display geologic and oceanographic information.

Waterproof camera is submerged and connected to GPS receiver at the surface with Red Hen Systems VMS 300 hardware. Georeferenced video and still photos are collected. Visual observations are of variable unknown accuracy.
Point features present.
Observation are from one minute intervals. Some gaps in observations are due to technical problems or sediment dispersion covering the camera lens.
Highly variable, on the order of 10 meters.
The camera-sled tracklines were sited through video fed up to the research vessel in real time, where USGS and NOAA scientists recorded both the geologic and biologic character of the seafloor. While the camera was deployed, observations were recorded for a 10-second period once every minute. Onshore, the observation comma-delimited text file was converted to an ArcGIS shapefile.
