Relative Intensity of Commercial Mid-Water Trawling off the U.S. West Coast (1 Jan 2002 – 11 Jun 2006)

This data layer depicts the relative intensity of commercial mid-water trawling off the U.S. West Coast from 1 Jan 2002 –11 Jun 2006. Records of mid-water trawl tows were compiled from two data sources: 1) Logbook data originating from the state logbook programs and uploaded to the Pacific Fisheries Information Network (PacFIN) regional database, and 2) observer records from the At-Sea Hake Observer Program (A-SHOP). These two data sources represent the shoreside and at-sea hake fleets, respectively. Included in the A-SHOP data are observations of tribal fishing in the at-sea hake sector. The intensity layer is a raster layer with cell values representing the total length of all towlines intersecting a standardized area. To calculate this metric, a line density algorithm in ArcGIS™ geographical information system software (Environmental System Research Institute, Incorporated, Redlands, California) was used. The line density algorithm calculates density within a circular search area (radius = 3 km) centered at a grid cell (size 500 m x 500 m). The value (units: km/km2) for each raster cell is the quotient of total towline portions intersecting the circular area per cell area. Since density outputs are highly sensitive to the specified radius and cell size, the absolute values are less important than the relative nature of them. The benefit of this output over depicting towlines themselves is that the density output better identifies areas where fishing effort is concentrated, while still ensuring confidentiality of individual fishing locations. The initial density output was more spatially extensive than the one shown in the figures, because it included cells with density values calculated from tows made by less than three vessels. Those “confidential”cells were removed for the final published data layer. Density parameters were chosen in order to minimize data exclusion (due to confidentiality mandates) while still providing a fairly high spatial resolution (500 x 500 m). Within this time period, only 3.1% of all effort (i.e., length of towlines) was excluded from the published raster layer, although the proportion varies considerably in certain areas along the coast. This spatial summary of mid-water trawl effort was developed from data represented only by start and end points of tows. It is recognized that tows rarely follow straight-line paths; however, this was the best information available on the spatial distribution of effort for vessels using mid-water trawl gears. Because of their patchy spatial distributions, towlines for mid-water trawls occurring south of Cape Mendocino were removed from the analysis at the request of the state of California.

Clean Water Act


The Clean Water Act (CWA) establishes the basic structure for regulating discharges of pollutants into U.S. waters and regulating quality standards for surface waters. The basis of the CWA was enacted in 1948 and was called the Federal Water Pollution Control Act, but the Act was significantly reorganized and expanded in 1972. "Clean Water Act" became the Act's common name through amendments in 1977.  The CWA's goal is to restore and maintain the chemical, physical, and biological integrity of the Nation's waters.

Habitat--Offshore of Bodega Head, California


This part of DS 781 presents data for the habitat map of the seafloor of the Offshore of Bodega Head map area, California. The vector data file is included in "Habitat_OffshoreBodegaHead.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreBodegaHead/data_catalog_OffshoreBodegaHead.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.

Backscatter B [7125]--Offshore of Fort Ross, California


This part of DS 781 presents data for the acoustic-backscatter map of the Offshore of Fort Ross map area, California. Backscatter data are provided as separate grids depending on mapping system or processing method. The raster data file is included in "BackscatterB_7125_OffshoreFortRoss.zip", which is accessible from http://pubs.usgs.gov/ds/781/OffshoreFortRoss/data_catalog_OffshoreFortRoss.html.

The acoustic-backscatter map of the Offshore of Fort Ross map area, California, was generated from backscatter data collected by California State University, Monterey Bay (CSUMB) and by Fugro Pelagos. Mapping was completed between 2007 and 2010, using a combination of 200-kHz and 400-kHz Reson 7125, and 244-kHz Reson 8101 multibeam echosounders, as well as 468-kHz SEA SWATHPlus interferometric system. These mapping missions combined to collect backscatter data from about the 10-m isobath to beyond the 3-nautical-mile limit of California State Waters.  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 composition. 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). These data are not intended for navigational purposes.

Real-time Wave Data - CDIP Wave Buoys (West Coast)

The Coastal Data Information Program (CDIP) consists of a network of nearshore Datawell Waverider buoys that measure significant wave height, peak period, peak direction and sea surface temperature in real-time. Measurements are taken every 30 minutes, and buoys transmit data via Iridium satellite communication capabilities. CDIP also produces a coastal wave height model, based on two wave models: the NOAA/NCEP Wavewatch III model for depths >300m, and a wave propagation model for water depths of 10-300m.

SANPHAB -- Habitat polygons for South Anacapa Passage (UTM 10N, NAD83)

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.  Anacapa Reserve, is part of the Marine Ecological Reserves Research Program (MERRP).  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.

Monthly and annual mean seawater temperature, salinity and density from 26 tide gauge sites during 1855-1993 (NODC Accession 0000817)

Tidal observers at primary tide gauges of the United States Coast and Geodetic Survey (now the NOAA National Ocean Service) routinely measured seawater temperature and density throughout most of the 20th century with select sites well before. All available records for 26 sites have been digitized, although more paper file records may still exist for others. Students at Florida Institute of Technology provided the key entry and quality control. The purpose was to study trends in sea water temperature and density in support of increasing the scientific understanding of low-frequency changes across a wide spatial domain of the coastal United States.

Anchorage Areas

An anchorage area is a place where boats and ships can safely drop anchor. These areas are created in navigable waterways when ships and vessels require them for safe and responsible navigation. A variety of designations refer to types of anchorage areas or restrictions, or even to alerts of potential dangers within an anchorage area. Every boater and captain should be aware of the various types of anchorage areas. These data are intended for coastal and ocean planning. Not for navigation.

10mCONTOUR - 10 meter bathymetric contours of the Gulf of the Farallones region

In 1989, the U.S. Geological Survey (USGS) began a major geologic and oceanographic investigation of the Gulf of the Farallones continental shelf system, designed to evaluate and monitor human impacts on the marine environment (Karl and others, 2002). The study region is located off the central California coast, adjacent to San Francisco Bay and encompasses the Gulf of the Farallones National Marine Sanctuary. Geologic mapping of this area included the use of various remote sensing and sampling techniques such as sub-bottom profiling, sidescan-sonar and bathymetric mapping, gravity core and grab sampling, and photography. These data were used to define the surficial sediment distribution, underlying structure and sea floor morphology of the study area.

The primary focus of this report is to present a georeferenced, digital sidescan-sonar mosaic of the study region. The sidescan-sonar data were acquired with the AMS-120 (120kHz) sidescan-sonar system during USGS cruise F9-89-NC. The dataset covers approximately 1000 km squared of the continental shelf between Point Reyes, California and Half Moon Bay, California, extending west to the continental shelf break near the Farallon Islands. The sidescan-sonar mosaic displays a heterogenous sea-floor environment, containing outcropping rock, ripples, dunes, lineations and depressions, as well as flat, featureless sea floor (Karl and others, 2002). These data, along with sub-bottom interpretation and ground truth data define the geologic framework of the region.  The sidescan-sonar mosaic can be used with supplemental remote sensing and sampling data as a base for future research, helping to define the local current regime and predominant sediment transport directions and forcing conditions within the Gulf of Farallones.

Bathymetry--Offshore of Carpinteria, California

This part of SIM 3261 presents data for the bathymetry and shaded-relief maps (see sheets 1, 2, SIM 3261) of the Offshore of Carpinteria map area, California. The raster data file for the bathymetry map is included in "Bathymetry_OffshoreCarpinteria.zip." The raster data file for the shaded-relief map is included in "BathymetryHS_OffshoreCarpinteria.zip." Both are accessible from http://pubs.usgs.gov/ds/781/OffshoreCarpinteria/data_catalog_OffshoreCarpinteria.html.
The bathymetry and shaded-relief maps of the Offshore of Carpinteria map area, California, were generated from bathymetry data collected by California State University, Monterey Bay, Seafloor Mapping Lab (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. The southeastern nearshore and shelf areas, as well as the western midshelf area, were mapped by CSUMB in the summer of 2007, using a 244-kHz Reson 8101 multibeam echosounder. The western nearshore area, as well as the western outer shelf area, were mapped by the USGS in 2005 and 2006, using 117-kHz and 234.5-kHz SEA (AP) Ltd. SWATHplus-M phase-differencing sidescan sonars. 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.
