This part of DS 781 presents video observations from cruise C0111SC in southern California. The vector data file is included in "c0111sc_video_observations.zip," which is accessible from https://pubs.usgs.gov/ds/781/video_observations/data_catalog_video_observations.html.
Video observations from cruise C0111CSC will be published in 23 future Scientific Investigations Maps in the California State Waters Map Series (namely, Offshore of Point Dume, Offshore of Malibu Point, Offshore of Santa Monica, Offshore of Palos Verdes, Offshore of San Pedro, Offshore of Long Beach, Offshore of Huntington Beach, Offshore of Newport Beach, Offshore of Dana Point, Offshore of San Onofre, Offshore of Oceanside, Offshore of Encinitas, Offshore of Del Mar, Offshore of Mission Beach, and Offshore of Imperial Beach map areas).
In 1999 and 2009, the seafloor in the Offshore of Point Dume, Offshore of Malibu Point, Offshore of Santa Monica, Offshore of Palos Verdes, Offshore of San Pedro, Offshore of Long Beach, Offshore of Huntington Beach, Offshore of Newport Beach, Offshore of Dana Point, Offshore of San Onofre, Offshore of Oceanside, Offshore of Encinitas, Offshore of Del Mar, Offshore of Mission Beach, and Offshore of Imperial Beach map areas in southern 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 2011 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.

Water proof 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 of variable unknown accuracy.
Point features present.
Observation are from one minute intervals. Some gaps in observations exist 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. On shore the observation comma delimited text file was converted to an ArcGIS shapefile.
