Identification_Information: Citation: Citation_Information: Originator: Valerie Paskevich Publication_Date: Unpublished Material Title: MB_CANYON-SS - outline and extent of the Monterey Bay canon backscatter imagery Edition: 1.0 Geospatial_Data_Presentation_Form: vector digital data Online_Linkage: Description: Abstract: The sidescan sonar image of the shelf seafloor of the Monterey Bay area was mosaicked from data collected between 1995 and 1998. The sonar data was available in 24 separate tiles. This data layer shows the extent and coverage of the combined mosaics. Purpose: 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 the extent of the available sidescan sonar backscatter image collected, processed and digitally mosaicked by the U.S. Geological Survey.
