Backscatter--Offshore of Point Conception Map Area, California

This part of DS 781 presents 2-m-resolution data for the acoustic-backscatter map of the Offshore of Point Conception Map Area, California. The GeoTiff is included in "Backscatter_OffshorePointConception.zip," which is accessible from https://doi.org/10.5066/F7QN64XQ. These data accompany the pamphlet and map sheets of Johnson, S.Y., Dartnell, P., Cochrane, G.R., Hartwell, S.R., Golden, N.E., Kvitek, R.G., and Davenport, C.W. (S.Y. Johnson and S.A. Cochran, eds.), 2018, California State Waters Map Series—Offshore of Point Conception, California: U.S. Geological Survey Open-File Report 2018–1024, pamphlet 36 p., 9 sheets, scale 1:24,000, https://doi.org/10.3133/ofr20181024. This acoustic-backscatter map of the Offshore of Point Conception map area in southern California was generated from acoustic-backscatter data collected by Fugro Pelagos Inc. Acoustic mapping was completed in 2008 using a combination of 400-kHz Reson 7125, 240-kHz Reson 8101, and 100-kHz Reson 8111 multibeam echosounders. These acoustic-backscatter data cover the area from about the 10-m isobath to beyond the limit of California’s State Waters.
