Habitat--Offshore of Ventura, California

This part of SIM 3254 presents data for the habitat map of the seafloor (see sheet 7, SIM 3254) of the Offshore of Ventura map area, California. The vector data file is included in "Habitat_OffshoreVentura.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreVentura/data_catalog_OffshoreVentura.html.
Using multibeam echosounder (MBES) bathymetry and backscatter data, potential marine benthic habitat maps were constructed. The habitats were based on substrate types and documented or "ground truthed" using underwater video images and seafloor samples obtained by the USGS. These maps display various habitat types that range from flat, soft, unconsolidated sediment-covered seafloor to hard, deformed (folded), or highly rugose and differentially eroded bedrock exposures. Rugged, high-relief, rocky outcrops that have been eroded to form ledges and small caves are ideal habitat for rockfish (Sebastes spp.) and other bottom fish such as lingcod (Ophiodon elongatus). Habitat map is presented in a map format generated in a GIS (ArcMap), and both digital and hard-copy versions will be produced.

Bathymetry Hillshade--Offshore of San Francisco, California


This part of DS 781 presents data for the bathymetry and shaded-relief maps  of Offshore of San Francisco, California (raster data file is included in "BathymetryHS_OffshoreSanFrancisco.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreSanFrancisco/data_catalog_OffshoreSanFrancisco.html.

The bathymetry and shaded-relief maps of Offshore of San Francisco, California, were generated from bathymetry data collected by Fugro Pelagos, and by California State University, Monterey Bay (CSUMB). Mapping was completed between 2004 and 2008, using a combination of 400-kHz Reson 7125 and 244-kHz Reson 8101 multibeam echosounders. These mapping missions combined to collect bathymetry (sheets 1, 2) from about the 10-m isobath to beyond the 3-nautical-mile limit of California's State Waters. A large portion of this map area was re-mapped in 2009, however the older bathymetry data were used in this map due to co-registered, acoustic backscatter data.

SED_ARCHIVE - Database for the U.S. Geological Survey Woods Hole Science Center's marine sediment samples, including locations, sample data and collection information

The U.S. Geological Survey (USGS), Woods Hole Science Center (WHSC) has been an active member of the Woods Hole research community for over 40 years. In that time there have been many sediment collection projects conducted by USGS scientists and technicians for the research and study of seabed environments and processes. These samples are collected at sea or near shore and then brought back to the WHSC for study. While at the Center, samples are stored in ambient temperature, cold or freezing conditions, depending on the best mode of preparation for the study being conducted or the duration of storage planned for the samples. Recently, storage methods and available storage space have become a major concern at the WHSC. The shapefile sed_archive.shp, gives a geographical view of the samples in the WHSC's collections, and where they were collected along with images and hyperlinks to useful resources.

NORCAL1952_1971 - Vectorized Shoreline of Northern California Derived from 1952-1971 Source Data

There are critical needs for a nationwide compilation of reliable shoreline data.  To meet these needs, the U.S. Geological Survey (USGS) has produced a comprehensive database of digital vector shorelines by compiling shoreline positions from pre-existing historical shoreline databases and by generating historical and modern shoreline data.  Shorelines are compiled by state and generally correspond to one of four time periods: 1800s, 1920s-1930s, 1970s, and 1998-2002.  Each shoreline may represent a compilation of data from one or more sources for one or more dates provided by one or more agencies.  Details regarding source are provided in the 'Data Quality Information' section of this metadata report.  Shoreline vectors derived from historic sources (first three time periods) represent the high water line at the time of the survey, whereas modern shorelines (final time period) represent the mean high water line.

Backscatter B [USGS]--Offshore of Santa Barbara, California

This part of SIM 3281 presents data for part of the acoustic-backscatter map (see sheet 3, SIM 3281) of the Offshore of Santa Barbara map area, California. The raster data file is included in "BackscatterB_USGS_OffshoreSantaBarbara.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreSantaBarbara/data_catalog_OffshoreSantaBarbara.html.
The acoustic-backscatter map of the Offshore of Santa Barbara map area, California, was generated from backscatter data collected by California State University, Monterey Bay, Seafloor Mapping Lab (CSUMB) and by the U.S. Geological Survey (USGS). These metadata describe the acoustic-backscatter data collected by the USGS. See "BackscatterA_CSUMB_OffshoreSantaBarbara_metadata.txt" metadata for a description of the acoustic-backscatter data collected by CSUMB. Small areas in the far-east nearshore, as well as further offshore to the west and in the southeast outer shelf area, were mapped by the USGS in 2005 and 2006, using a combination of 468-kHz (2005) and 117-kHz (2006) SEA (AP) Ltd. SWATHplus-M phase-differencing sidescan sonars. Within the acoustic-backscatter imagery, brighter tones indicate higher backscatter intensity, and darker tones indicate lower backscatter intensity. The intensity represents a complex interaction between the acoustic pulse and the seafloor, as well as characteristics within the shallow subsurface, providing a general indication of seafloor texture and sediment type.  Backscatter intensity depends on the acoustic source level; the frequency used to image the seafloor; the grazing angle; the composition and character of the seafloor, including grain size, water content, bulk density, and seafloor roughness; and some biological cover.  Harder and rougher bottom types such as rocky outcrops or coarse sediment typically return stronger intensities (high backscatter, lighter tones), whereas softer bottom types such as fine sediment return weaker intensities (low backscatter, darker tones).

Transgressive Contours--Bolinas to Pescadero, California


This part of DS 781 presents data for the transgressive contours for the Bolinas to Pescadero, California, region. The vector file is included in "TransgressiveContours_BolinastoPescadero.zip," which is accessible from http://pubs.usgs.gov/ds/781/BolinastoPescadero/data_catalog_BolinastoPescadero.html.
These transgressive contours for the Bolinas to Pescadero region are published in Scientific Investigations Map 3306, "California State Waters Map Series--Offshore San Gregorio, California" (see sheet 9). In addition, these transgressive contours will be published in five future California State Waters Map Series Open-File Reports of the region (namely, the Offshore of San Francisco, Offshore of Pacifica, Offshore of Half Moon Bay, Offshore of San Gregorio, and Offshore of Pigeon Point map areas).
As part of the USGS's California State Waters Mapping Project, a 50-m grid of depth to the transgressive surface of the last glacial maximum was generated for the areas within the 3-nautical mile limit between Bolinas and Pescadero was generated from seismic-reflection data collected in 2010 (USGS activity (S-15-10-NC)  and 2007 (F-2-07-NC) supplemented with outcrop and geologic structure as mapped by Watt and others (Sheet 8, Sheet 10). The resulting grid covers an area of approximately 550 sq km. The depth to the transgressive surface of the Last Glacial Maximum ranges between 4 and 78 meters.

SMIGHAB -- Habitat polygons for the nearshore San Miguel Island, Channel Islands NMS

Benthic habitat polygon coverages have been created for marine reserve locations surrounding the Santa Barbara Basin.  Diver, ROV and submersible video transects, bathymetry data, sedimentary samples, and sonar mapping, have been integrated to describe the geological, biological, and oceanographic aspects of habitat.  The U.S. Geological Survey (USGS), in a cooperative project with Sea Grant-MERRP and investigators at National Marine Fisheries Service (NMFS), the Channel Islands National Marine Sanctuary (CINMS), and National Park Service (NPS) has collected sidescan sonar and video data to produce a polygon coverage.  The habitat polygons have attributes for megahabitat, bottom induration, macrohabitat (where macrohabitat observations are available), polygon area, polygon perimeter, and water depth.  The habitat GIS shows rocky habitat suitable for rockfish (Sebastes sp.), abalone (Haliotis sp.), and other threatened benthic species from the shoreline out to the 100-m depth limit of the survey.

The acoustic-backscatter map of the Offshore of Ventura map area, California, was generated from backscatter data collected by California State University, Monterey Bay, Seafloor Mapping Lab (CSUMB) and by the U.S. Geological Survey (USGS). These metadata describe the acoustic-backscatter data collected by CSUMB and reprocessed by the USGS (see "BackscatterB_USGS_OffshoreVentura_metadata.txt" metadata for a description of the acoustic-backscatter data collected by the USGS). The majority of the acoustic-backscatter data within the Offshore of Ventura map area, California, was collected by CSUMB in the summers of 2006 and 2007, using a 244-kHz Reson 8101 multibeam echosounder. Within the final imagery, brighter tones indicate higher backscatter intensity, and darker tones indicate lower backscatter intensity. The intensity represents a complex interaction between the acoustic pulse and the seafloor, as well as characteristics within the shallow subsurface, providing a general indication of seafloor texture and sediment type.  Backscatter intensity depends on the acoustic source level; the frequency used to image the seafloor; the grazing angle; the composition and character of the seafloor, including grain size, water content, bulk density, and seafloor roughness; and some biological cover.

PAC_PRS - Parsed seabed data for the continental margin of the U.S. Pacific Coast (California, Oregon, Washington) from usSEABED (pac_prs.txt)

This data layer (PAC_PRS.txt) is one of five point coverages of known sediment samples, inspections, and probes from the usSEABED data collection for the U.S. Pacific continental margin integrated using the dbSEABED software system.  This data layer represents the parsed (PRS) output of the dbSEABED mining software. It contains the numeric results parsed from text-based descriptions held in the data resource files (DRF). Because it relies on descriptions, the PRS data are less precise than the extracted data (PAC_EXT), but may include information on outsized elements and consolidation that are often not in lab-analyzed data.  This file contains the same data fields as the extracted (PAC_EXT) and calculated (PAC_CLC) data files, and the three files may be combined.

Clean Water Act

These data represent geographic terms used within the Clean Water Act (CWA). The CWA establishes the basic structure for regulating the addition of pollutants (discharges) into waters of the United States, a three mile territorial sea, a 12 mile contiguous zone, and the ocean. The goal of the CWA is to restore and maintain the chemical, physical, and biological integrity of the Nation's waters. This data includes two component boundaries, which delineate the seaward extent of various parts of the CWA. The boundary of a three mile territorial sea and 12 mile contiguous zone are relevant to application of various discharge standards associated with vessels or other floating craft, that vary depending on operational status. As referenced within the CWA, these two boundaries are based on the 1958 Convention on the Territorial Sea and the Contiguous Zone, and not the contemporary extent of these respective boundaries. While the Exclusive Economic Zone (EEZ) is not specified with the CWA, it is denoted here for illustrative purposes. The CWA does not include inland waters because 1) it is difficult to properly identify the nationwide extent of all inland water bodies, and 2) there is current litigation with EPA of such water bodies falling under the jurisdiction of the CWA. When investigating geo-regulatory boundaries near the boundary edges, users should consult the most up-to-date applicable jurisdictional boundaries from all respective authoritative sources.

Bathymetry--Offshore of San Francisco, California


This part of DS 781 presents data for the bathymetry and shaded-relief maps  of Offshore of San Francisco, California (raster data file is included in "Bathymetry_OffshoreSanFrancisco.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreSanFrancisco/data_catalog_OffshoreSanFrancisco.html.

The bathymetry and shaded-relief maps of Offshore of San Francisco, California, were generated from bathymetry data collected by Fugro Pelagos, and by California State University, Monterey Bay (CSUMB).

A large portion of this map area was re-mapped in 2009, however the older bathymetry data were used in this map due to co-registered, acoustic backscatter data.

NOTE: the horizontal datum of the bathymtry data (NAD83) differs from the horizontal datum of other layers in this SIM (WGS84). Some bathymetry grids within this map were projected horizontally from WGS84 to NAD83 using ESRI tools to be more consistent with the vertical reference of the North American Vertical Datum of 1988 (NAVD88). These data are not intended for navigational purposes.

PaCSEA Bird Survey Summary Data, 2011-2012

This data set was created as a summary layer to more easily represent the original PaCSEA bird transect counts at a consistent scale across the transect for display within MarineCadastre.gov. These map layers display the density of birds (birds/sq km) detected in the Pacific Continental Shelf Environmental Assessment (PaCSEA) 2011 – 2012. PaCSEA involved repeated low-elevation aerial surveys along 32 broad-scale transects to quantify seabirds and marine mammals from shore to the 2000-m isobath. Transects were spaced 15 nautical miles (nmi) apart, between Fort Bragg, California (39° N) and Grays Harbor, Washington (47° N). Surveys were conducted from fixed wing aircraft flying 160 km/h at 60-m above sea level. All birds and marine mammals within a 150 m transect (75 m per side) were counted. Six complete surveys were conducted with 3 surveys each year (winter, summer, and fall). While the actual area sampled varied slightly among surveys, this summary representation uses 6.8 x 6.8 km polygons to display estimates of bird density for all surveys.  The actual transect areas are also included in a single file for all 6 surveys. Please consult the metadata file for information and file access for the original study products.
