Abstract:

This part of DS 781 presents data for the bathymetric contours of the Hueneme Canyon and Vicinity map area, California. The vector data file is included in "Contours_HuenemeCanyon.zip," which is accessible from https://pubs.usgs.gov/ds/781/HuenemeCanyon/data_catalog_HuenemeCanyon.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., Kvitek, R.G., Greene, H.G., Krigsman, L.M., Endris, C.A., Clahan, K.B., Sliter, R.W., Wong, F.L., Yoklavich, M.M., and Normark, W.R. (S.Y. Johnson, ed.), 2012, California State Waters Map Series—-Hueneme Canyon and Vicinity, California: U.S. Geological Survey Scientific Investigations Map 3225, 41 p., 12 sheets, scale 1:24,000, https://pubs.usgs.gov/sim/3225/.

The bathymetry map of Hueneme Canyon and Vicinity map area in southern California was generated from bathymetry data collected by California State University, Monterey Bay (CSUMB), by the U.S. Geological Survey (USGS), and by Fugro Pelagos for the U.S. Army Corps of Engineers (USACE) Joint Lidar Bathymetry Technical Center of Expertise. Most of the offshore area was mapped by CSUMB in the summers of 2006 and 2007, using a 244-kHz Reson 8101 multibeam echosounder. The far-northern part of the offshore area was mapped by the USGS in 2006, using a 117-kHz SEA (AP) Ltd. SWATHplus-M phase-differencing sidescan sonar. The nearshore bathymetry and coastal topography were mapped for USACE by Fugro Pelagos in 2009, using the SHOALS-1000T bathymetric-lidar and Leica ALS60 topographic-lidar systems. All these mapping missions combined to collect bathymetry from the 0-m isobath to beyond the 3-nautical-mile limit of California's State Waters. To generate contours, a smooth arithmetic mean convolution function was applied to the bathymetry. Following smoothing, contour lines were generated at 10-meter intervals from -10 m to -100 m and at 50-meter intervals from -100 m to -400 m.

Purpose:

These data are intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems or other software to identify bathymetric features.

Process_Description:

The bathymetry map of Hueneme Canyon and vicinity in southern California was generated from data collected by California State University, Monterey Bay (CSUMB), by the U.S. Geological Survey (USGS), and by Fugro Pelagos for the U.S. Army Corps of Engineers (USACE) Joint Lidar Bathymetry Technical Center of Expertise. All these mapping missions combined to collect bathymetry from the 0-m isobath to beyond the 3-nautical-mile limit of California's State Waters. Final XYZ soundings and bathymetric-surface models were referenced to the World Geodetic System of 1984 (WGS 1984) relative to the North American Vertical Datum of 1988 (NAVD 1988). Once all the bathymetric-surface models were transformed to a common projection and datum, the files were merged into one overall 2-m-resolution bathymetric-surface model. Bathymetry data for the Santa Barbara Channel out to the 3-nautical-mile limit were mosaicked using the mosaic function in ArcGIS 10, with the FIRST operator. Data were merged in the following order (source in parentheses): sbc_a(CSUMB), sbc_b(CSUMB), sbc_c(CSUMB), sbc_d(CSUMB), sbc_e(CSUMB), sbc_f(CSUMB), sbc_g(CSUMB), sbc_h(CSUMB), S-8-08-SC(USGS), S-1-05-SC(USGS), Z-1-07-SC(USGS), Z-2-06-SC(USGS), H11950_2mbthy(Fugro via CSUMB), H11950_5mbthy(Fugro via CSUMB), H11951_2mbthy(Fugro via CSUMB), H11951_5m_MLLW_6of7(Fugro via FGDC), H11952_2mbthy(Fugro via CSUMB), H11953_2mbthy(Fugro via CSUMB). After merging, data were exported at 10-m resolution in WGS84 UTM 11N and clipped to the the Hueneme Canyon and Vicinity, California, map boundary. A smooth arithmetic mean convolution function applying a weight of one-ninth to each cell in a 3-pixel by 3-pixel matrix was then applied iteratively to the grid ten times. Following smoothing, contour lines were generated at 10-meter intervals from -10 m to -100 m and at 50-meter intervals from -100 m to -350 m (the maximum depth in the grid is -398.65 m). Small gaps in contours were connected while leaving the CONTOUR fields blank to facilitate identification.

Attribute:

Attribute_Label: CONTOUR
Attribute_Definition:

Contours are lines that connect points of equal depth based on the bathymetry grid. The contour values indicate the depth value the line represents. This makes it easier to identifier features on the seafloor. After smoothing of the bathymetry grid, contour lines were generated at 10-meter intervals from -10 m to -100 m and at 50-meter intervals from -100 m to -350 m (the maximum depth in the grid is -398.65 m). Values are negative to indicate depth below sea level. The value of 0 represents a line segment created during the smoothing process.
