Description This part of DS 781 presents video observations from cruise S1C08SC for the Santa Barbara Channel region and beyond in southern California. The vector data file is included in "s1c08sc_video_observations.zip," which is accessible from http://pubs.usgs.gov/ds/781/video_observations/data_catalog_video_observations.html. Some of the video observations from cruise S1C08SC are published in Scientific Investigations Map 3225, "California State Waters Map Series--Hueneme Canyon and Vicinity, California" (see sheet 6). In addition, some of the video observations will be published in eight future California State Waters Map Series SIMs of the region (namely, the Mugu Canyon and Vicinity, Offshore of Ventura, Offshore of Carpinteria, Offshore of Santa Barbara, Offshore of Coal Oil Point, Offshore of Refugio Beach, Offshore of Gaviota, and Offshore of Point Conception map areas) [note that, at the time of this writing, two of the other eight SIMs have been published: the Offshore of Ventura map area (SIM 3254), and the Offshore of Carpinteria map area (SIM 3261)]. Between 2006 and 2007, the seafloor in the Mugu Canyon and Vicinity, Hueneme Canyon and Vicinity, Offshore of Ventura, Offshore of Carpinteria, Offshore of Santa Barbara, Offshore of Coal Oil Point, Offshore of Refugio Beach, Offshore of Gaviota, and Offshore of Point Conception 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 (for example, see sheets 1, 2, and 3, SIM 3225, for details). 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. [More]
