Abstract:
This part of DS 781 presents data for the isopachs for the Santa Barbara Channel, California, region. The vector data file is included in "Isopachs_SantaBarbaraChannel.zip," which is accessible from <https://pubs.usgs.gov/ds/781/SantaBarbaraChannel/data_catalog_SantaBarbaraChannel.html>. These isopachs for the Santa Barbara Channel are published in Scientific Investigations Map 3225, "California State Waters Map Series--Hueneme Canyon and Vicinity, California" (see sheet 9). In addition, these isopachs will be published in five future California State Waters Map Series SIMs of the region (namely, the Offshore of Ventura, Offshore of Carpinteria, Offshore of Santa Barbara, Offshore of Coal Oil Point, and Offshore of Refugio Beach map areas) [note that, at the time of this writing, two of the other five SIMs have been published: the Offshore of Ventura map area (SIM 3254), and the Offshore of Carpinteria map area (SIM 3261)].
As part of the USGS's California Seafloor Mapping Program, a 50-m grid of sediment thickness for the seafloor within the 3-nautical-mile limit of California's State Waters from the Offshore of Refugio Beach map area to the Hueneme Canyon and vicinity map area. Source data include seismic-reflection profile data, collected in 2007 (USGS cruise Z-3-07-SC) and 2008 (USGS cruise S-7-08-SC), supplemented with outcrop and geologic structure data (for example, sheets 8, 10, SIM 3225). The resulting grid covers an area of approximately 600 sq km. The volume of sediment accumulated since the Last Glacial Maximum is approximately 9,000 million cubic meters. Contours at 2.5-meter intervals were derived from this grid.
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 geologic and oceanographic information.
