Seafloor character--Offshore of Refugio Beach, California
This part of DS 781 presents the seafloor-character map of the Offshore of Refugio Beach map area, California. The raster data file is included in "SeafloorCharacter_OffshoreRefugioBeach.zip," which is accessible from https ://pubs.usgs.ov/ds/781/OffshoreRefugioBeach/data_catalog_OffshoreRefugioBeach.html). These data accompany the pamphlet and map sheets of Johnson, S.Y., Dartnell, P., Cochrane, G.R., Golden, N.E., Phillips, E.L., Ritchie, A.C., Krigsman, L.M., Dieter, B.E., Conrad, J.E., Greene, H.G., Seitz, G.G., Endris, C.A., Sliter, R.W., Wong, F.L., Erdey, M.D., Gutierrez, C.I., Yoklavich, M.M., East, A.E., and Hart, P.E. (S.Y. Johnson and S.A. Cochran, eds.), 2015, California State Waters Map Series—Offshore of Refugio Beach, California: U.S. Geological Survey Scientific Investigations Map 3319, pamphlet 42 p., 11 sheets, scale 1:24,000, https://doi.org/10.3133/sim3319.
This raster-format seafloor-character map shows five substrate classes of Offshore of Refugio Beach, California. The substrate classes mapped in this area have been divided into the following California Marine Life Protection Act depth zones and slope classes: Depth Zone 2 (intertidal to 30 m), Depth Zone 3 (30 to 100 m), Depth Zone 4 (100 to 200 m), Slope Class 1 (0 degrees - 5 degrees), and Slope Class 2 (5 degrees - 30 degrees). Depth Zone 1 (intertidal); Depth Zone 5 (greater than 200 m), and Slope Classes 3-4 (greater than 30 degrees) are not present in this map area. The map is created using a supervised classification method described by Cochrane (2008).
