  2. Title: Bathymetric Digital Elevation Model (200 meters): California Coast, 2002

    Contributors:

    Summary: This raster dataset is a mosaic resampled to 200 meter horizontal resolution for areas of sparse data occurrence. Vertical units are fathoms (integer). The tiled 25 meter base DEMs are intermediate products used to generate the 25-200 meter zonal DEMs. These 25, 50, 100 and 200 meter "zones" were defined by plotting the source data on paper, visually identifying and hand drafting zone boundaries based on data density, then capturing the boundaries in digital format. The tiled 5-200 meter zonal DEMs are simply the coast-wide zonal DEMs (or individual 5 meter zonal DEMs) clipped to a 7500 meter buffered tile extent and stored in the tile directory. This makes it easy to find DEMs of all available resolutions for a single tile. Tile directories store only those resolutions that cover the tile. A single coast-wide Digital Elevation Model (DEM) was envisioned as the product of the California Department of Fish and Game bathymetry development project, but it quickly became evident that the source data necessitated multiple datasets, including: 1) Coast-wide 25, 50, 100 and 200 meter zonal DEMs; 2) 5 meter zonal DEMs for localities supported by high-density source data; 3) Tiled 5, 25, 50, 100 and 200 meter zonal DEMs; and 4) Tiled 25 meter base DEMs. The grid is a resampled compilation of these datasets (available upon request). The bathymetry development project covered most of the 200 nautical mile Exclusive Economic Zone (EEZ) off the coast of California. The actual extent of data is slightly beyond this zone in some areas to account for the 100 km. tiles used to process source data (some tiles extend beyond the EEZ boundary by as much as almost a tile width, or less than 100 km.). To the east, the coverage includes many major inlets along the coast. The tiles also extend north and south of California by less than one tile height. These data are not suitable for navigation purposes. California Department of Fish and Wildlife, 2003. Bathymetric Digital Elevation Model (200 meters): California Coast, 2002. Marine Region GIS Lab.

The bathymetry data are not suitable for navigation. DFG makes no warranty as to the suitability of the bathymetry data, and any project-related datasets, for any purpose. In addition to this readme file, other documentation files (text, XML, etc.) may accompany datasets related to this project. ACKNOWLEDGEMENTS The bathymetry processing methods and documentation were originally developed by the State of California Stephen P. Teale Data Center, GIS Solutions Group (Teale) under DFG direction. Key Teale staff involved in the project included Andy Richardson and Virginia Wong-Coppin. REVISIONS A second edition of the bathymetry data was completed by DFG in August 2002. The second edition data were processed using ARC/INFO GIS software in a Windows 2000 operating system environment and included the following enhancements: - Correction or exclusion of over 1700 miscoded and suspicious Hydrographic Surveys used in the bathymetry development process. - Replacement of older U.S. Geological Survey 7.5-minute terrestrial elevation data with the newer/higher-quality National Elevation Dataset (NED) for use in nearshore bathymetry interpolation. - Minor adjustments to some of the ARC/INFO software ARC Macro Language (AML) scripts and resolution zone boundaries used to process the bathymetry data. GEOGRAPHIC AREA Bathymetry was developed to cover most of the 200 nautical mile Exclusive Economic Zone (EEZ) off the coast of California. The actual extent of data is slightly beyond this zone in some areas to account for the 100 kilometer tiles used to process source data (some tiles extend beyond the EEZ boundary by as much as almost a tile width, or less than 100 KM). To the east, the coverage includes many major inlets along the coast. The tiles also extend north and south of California by less than 1 tile height. VITAL STATISTICS Data Format: ESRI grid (DEMs) Horizontal Datum: NAD27 (spheroid: Clarke 1866) Projection: Albers conic equal area Units: Meters Z-Units (depth values): Decimeters (land coded as zero) 1st Std. Parallel: 34 00 00 (34.0 degrees N) 2nd Std.

Upon commencing the project it became evident that due to the nature of the source data multiple datasets were appropriate. These include: 1. Coastwide 25, 50, 100, and 200 meter zonal DEMs 2. 5 meter zonal DEMs for localities supported by high-density source data 3. Tiled 5, 25, 50, 100, and 200 meter zonal DEMs 4. Tiled 25 meter base DEMs The coastwide 25-200 meter zonal DEMs are based on the fact that there is a wide variation in the density of the source data. Where data were dense, a 25 meter zonal DEM was generated. Where data were sparse, a 200 meter zonal DEM was generated. The 50 and 100 meter zonal DEMs represent intermediate densities. Though "coastwide", data in these DEMs do not overlap, however together they cover the entire study area. These 25, 50, 100, and 200 meter "zones" were defined by plotting the source data on paper, visually identifying and hand drafting zone boundaries based on data density, then capturing the boundaries in digital format. The 5 meter zonal DEMs correspond to areas where source data are particularly dense. These areas were identified by visually scanning the source data on-screen, and "heads up" digitizing the boundaries. These DEMs differ from the 25-200 meter zonal DEMs in that they were processed using different tolerances and that they were not merged into a single coastwide zonal DEM (due to resolution / storage constraints). These DEMs are available named by geographic localities or as tiled data. The tiled 5-200 meter zonal DEMs are simply the coastwide zonal DEMs (or individual 5 meter zonal DEMs) clipped to a 7500 meter buffered tile extent and stored in the tile directory. This makes it easy for a user to find DEMs of all available resolutions for a single tile. Tile directories store only those resolutions that cover the tile. The tiled 25 meter base DEMs are intermediate products used to generate the 25-200 meter zonal DEMs. These have proven useful as a source for generating contours and depth range polygons. They are also useful for visualizing and analyzing small geographic areas, though the user must understand that the source data do not necessarily support 25 meter resolution. These DEMs are tile-wide in extent, and are available clipped to the tile boundary (dembase) and buffered 7500 meters beyond the tile (dembaseb). An available georeferenced map image (bathy_map.jpg with bathy_map.jgw world file) shows spatial distribution, tile numbers, and resolution zones of the DEM data. SOURCE DATA Four sources of depth/elevation data were used to create the bathymetric DEMs: 1. Hydrographic Survey Data version 4.0, National Ocean Service (NOS), National Oceanic and Atmospheric Administration, U.S. Department of Commerce. Dataset name = hydsura (ESRI coverage format). 2. U.S. Geological Survey bathymetric contours for the California EEZ - 100m contours from 200m to maximum depth. Dataset name = eezbata (ESRI coverage format). 3. 30 meter terrestrial DEM based on the National Elevation Dataset (NED), U.S. Geological Survey, U.S. Department of the Interior. Dataset name = dema (ESRI grid format). 4. 1:24,000-scale State of California Coastline, State Lands Commission, State of California. Dataset name = rawclipa (ESRI coverage format). The NOS Hydrographic Surveys were the primary nearshore depth data used to create the bathymetric DEMs. These data represent multiple historical ship transects and were imported to ARC/INFO as a set of over 6 million points. Sampling density is quite variable, as close as a few meters in inland bays and as far apart as hundreds or thousands of meters away from the coast. The Hydrographic Surveys were processed as-is and not filtered to model a particular range of dates. The U.S. Geological Survey bathymetric contours were provided by the U. S. Geological Survey Coastal and Marine Geology Team. The original dataset known as "eezbatcall" was reprojected by DFG to the California (Teale) Albers projection. The coverage provided contours from 200 meters to maximum depth for the California EEZ area. The contours were digitized from various small-scale (approximately 1:1,000,000) U.S. Geological Survey maps. The 30 meter terrestrial DEM was used to allow continuous gridding along the coast. Though there is no land area included in the resulting products, the bathymetry gridding process requires sampling data beyond the edge of the resulting grid to smoothly interpolate depth/elevation along the edge. The NED terrestrial DEM data were distributed by the U.S. Geological Survey then processed and re-distributed by Teale. The 1:24,000 coastline was used to define land and water areas and as source depth points of "0". This results in a well-defined coastline in the bathymetric DEMs. The original State Lands Commission coastline coverage was modified by Teale for project purposes. PROCESSING DATA In addition to the source depth/elevation data, a number of datasets were used to control processing. These include: 1. TILE100KM 2. RES_ZONES 3. RAWCLIPA 4. M5_ZONES TILE100KM is a set of 100 kilometer square (10,000 square kilometers) tiles used to split the entire EEZ into 75 managable processing areas. Many of the resulting datasets are also stored by these tiles. RES_ZONES are zones corresponding to the density of source data that were used to determine the resolution of the resulting zonal DEMs (5, 25, 50, 100, and 200 meters). RAWCLIPA contains a set of polygons that define which areas are water and which areas are land. This dataset serves two functions in the gridding process. Coastlines are extracted, converted to a set of points with a depth value of "0", merged with the Hydrographic Surveys, U.S. Geological Survey bathymetric contours, terrestrial DEMs, and gridded. When gridding is complete, land polygons are pulled from this dataset and used to blank out the resulting DEM. M5_ZONES are areas where the Hydrographic Surveys support 5 meter gridding. The final products include a single 5 meter zonal DEM for each polygon in this dataset. PROCESSING METHODOLOGY The primary engine behind the gridding process is the ARC/INFO TOPOGRID tool. TOPOGRID uses an iterative finite difference interpolation technique that is essentially a discretized thin plate spline technology. It is based upon the ANUDEM program developed my Michael Hutchinson. The online help for TOPOGRID contains the following references: Hutchinson, M.F. 1988.

Wahba, G. 1990. Spline models for Observational data. CBMS-NSF Regional Conference Series in Applied Mathematics, Philadelphia: Soc. Ind. Appl. Maths. The following TOPOGRID parameters were used to create the 25-200 meter DEMs: DATATYPE SPOT ENFORCE OFF ITERATIONS 30 TOLERANCES 2.5 1.5 10 XYZLIMITS %LIMITS% (%LIMITS% = bounding box of buffered tile) The following TOPOGRID parameters were used to create the 5 meter DEMs: BOUNDARY XXZONE (XXZONE is the 5 meter zone polygon) DATATYPE SPOT ENFORCE OFF ITERATIONS 30 TOLERANCES 2.5 1.5 2.5 XYZLIMITS %LIMITS% (%LIMITS% is 50 meters beyond the 5 meter zone polygon bounding box) The processing logic applied to each of the 75 tiles to create the 25-200 meter DEMs was: - Receive the tile number to process - Create a results directory corresponding to the tile number - Extract the tile from TILE100KM - Buffer the tile 10 KM - Using the buffered tile, clip out: - RES_ZONES - RAWCLIPA (land water polygons) - Hydrographic Surveys - Coastlines (from RAWCLIPA) - Convert to points - Terrestrial DEM (if tile covers land area) - Convert to points - U. S. Geological Survey bathymetric contours (if tile covers 200 meter zone) - Merge all point coverages - Run TOPOGRID to create 25 meter DEM covering buffered tile area - Blank out land areas - Clip to 7500 meters beyond tile boundary; store in tile directory - Clip to tile boundary; store in tile directory - For each resolution zone covered by the tile: - Clip out area from buffered DEM - Resample to appropriate resolution for zone (using bilinear interpolation) - Blank out land areas - Store in tile directory The process used to create the 5 meter DEMs is: - For each polygon in M5_ZONES: - Create a coverage containing a single rectangle polygon 50 meters (10 5 meter cells) larger than the zone polygon - Using the rectangle, clip out: - RAWCLIPA (land water polygons) - Hydrographic Surveys - Coastlines (from RAWCLIPA) - Convert to points - Terrestrial DEM (if tile covers land area) - Convert to points - Merge the resulting point coverages - Run TOPOGRID to create 5 meter DEM covering the rectangle - Blank out land areas - Clip to extent of the zone polygon After the original tiled 25 meter base DEMs were created by Teale, shaded reliefs were generated and visually inspected. Miscoded points that resulted in spurious pits or spikes were identified and coded as such. After all errors were corrected for a tile, the DEMs for the tile were re-created and re-inspected. DIRECTORY STRUCTURE The following outline illustrates the directory structure used to process the bathymetry data. When fully populated, the TILEx directories are quite large (several gigabytes). - BATHYMETRY - AMLS (ARC/INFO AML data processing scripts) - DATA (source and processing data) - PROCESS (bathymetry processed here) - RESULTS (contains various results directories) - METER5 (5 meter zonal DEMs, named by localities) - OTHER (empty) - STATE (25, 50, 100, 200 meter coastwide zonal DEMs) - TILES (contains tile1-tile75 directories) - TILEx (contains tiled and base DEMs) - DEMBASE (25 meter base DEM clipped to tile) - DEMBASEB (25 meter base DEM buffered 7500 meters beyond tile) - DEM5 (5 meter zonal DEM buffered 7500 meters beyond tile) - DEM25 (25 meter zonal DEM buffered 7500 meters beyond tile) - DEM50 (50 meter zonal DEM buffered 7500 meters beyond tile) - DEM100 (100 meter zonal DEM buffered 7500 meters beyond tile) - DEM200 (200 meter zonal DEM buffered 7500 meters beyond tile) DATA QUALITY ASSESSMENT The following are subjective comments regarding the data. Because the bathymetry data were generated from a variety of sources at varying scales, overall accuracy is difficult to assess. The data have not been thoroughly reviewed. Depth values should be corroborated with other sources. Some "artifacts" are present in the data, and may be especially noticeable along resolution zone and tile boundaries where differing data sources may not have provided a smooth interpolation transition. Additional errors may be present. Source Hydrographic Survey data originated from many historical surveys and thus do not necessarily represent current hydrologic conditions. For accuracy assessments of Hydrographic Survey data, please reference the documentation for that product. DEM depth values are of particular questionable quality in the following areas. Other problem areas may exist. - Nearshore areas north of Mack Pt. (southern Oregon). Source terrestrial elevation data was missing for this area but depth values were still interpolated to the shoreline. - Nearshore, Gulf of the Farallones area, south of Stormy Stack and north of Muir Beach out to about -25 meters depth. Source depth data was missing for this area but depth values were still interpolated to the shoreline. - Nearshore areas south of the California border out to -200 meters depth. Source depth and terrestrial elevation data were missing for this area but depth values were still interpolated to the shoreline. - Any depth values outside of the gridding resolution zones. Cross-reference the "tile100km" and "res_zones" coverages used in data processing to determine areas within tiled DEMs that are outside the resolution zones. The georeferenced map image (bathy_map.jpg with bathy_map.jgw world file) can also be used for this purpose. - San Diego Bay. Source data were missing for portions of the bay but depth values were still interpolated. ACCESS LIMITATIONS None.

  3. Title: 50-Foot Bathymetric Contours: California, Continental Shelf, 2000

    Contributors:

    Summary: This polyline shapefile depicts bathymetric contour line coverage for California that generally covers the continental shelf at 50 foot contour resolution. The contours were developed by interpolating National Ocean Service (NOS) Hydrographic Survey depth points. The TopoGrid algorithm within ArcInfo software was the primary gridding interpolation procedure, followed by a standard contouring routine. The contours are one possible interpretation based on chosen contouring procedures. The purpose of this contour map is to visualize changes in ocean depths relative to sea level in the nearshore California continental shelf, which is the portion of the continent beneath the ocean’s surface. The bathymetric measurements used here refer to the study of water depths only and do not include the underwater, or submarine, topography of the ocean floor except as it relates to water depths. These data are not suitable for navigation purposes. California Department of Fish and Wildlife. (2001). 50-Foot Bathymetric Contours: California, Continental Shelf, 2000. Marine Region GIS Lab.

  4. Title: Coastal Barrier Resource System, Northeast United States, 1982-2008

    Contributors:

    Summary: The Coastal Barrier Resources Act (CBRA) of 1982 established the John H. Chafee Coastal Barrier Resources System (CBRS), comprised of undeveloped coastal barriers along the Atlantic, Gulf, and Great Lakes coasts. The law encourages the conservation of hurricane prone, biologically rich coastal barriers by restricting Federal expenditures that encourage development, such as Federal flood insurance through the National Flood Insurance Program. CBRA is a free-market approach to conservation. These areas can be developed, but Federal taxpayers do not underwrite the investments. CBRA saves taxpayer dollars and encourages conservation at the same time. CBRA has saved over $1 billion and will save millions more in the future. Approximately 3.1 million acres of land and associated aquatic habitat are part of the CBRS. The Fish and Wildlife Service maintains the repository for CBRA maps enacted by Congress that depict the CBRS. The Service also advises Federal agencies, landowners, and Congress regarding whether properties are in or out of the CBRS, and what kind of Federal expenditures are allowed in the CBRS. To support coastal planning and other activities pursuant to the Coastal Zone Management Act, Energy Policy Act, Magnuson-Stevens Fishery Conservation and Management Act, National Environmental Policy Act, Rivers and Harbors Act and the Submerged Lands Act.

  6. Title: California Coastal Trail, San Mateo County Sea Level Rise Vulnerability Assessment Project, 2012

    Contributors:

    Summary: This line shapefile represents sections of the California Coastal Trail in the San Mateo County Sea Level Rise Vulnerability Assessment Project area. Data from the National Park Service (Golden Gate National Recreation Area and Point Reyes National Seashore), the California Department of Parks and Recreation (Coastal State Park Units), the California Coastal Commission (SB908), and Coastwalk (2008 alignment) were used to create this dataset. Starting with the SB908 and Coastwalk 2008 the alignment of the trail was reviewed by staff at the Conservancy for accuracy and to make sure that newly completed projects were included. Once the route was reviewed data was used from NPS, CDPR, and 1m images to digitize the new alignment. Where the CCT was already established by NPS or CDPR their alignment for the route was followed. This alignment of the CCT was created to update the SB908 (2002) alignment and the Coastwalk (2008) alignments to include new sections of the CCT.

    Contributors:

    Summary: This product was created by the Nature Conservancy based on data provided by the National Marine Fisheries Service. The number of trips information is based on vessel trip report records that have been aggregated by ten minute square and have been screened for confidentiality. The records to produce this dataset are for federally permitted party boats and charter boats only. Vessel trip reports are submitted to the National Marine Fisheries Service by federally permitted fishing vessels for all fishing trips. The screening process protects the identity of each individual permitted commercial fishing vessel. Approximately 70% to 80% of all recorded of trips between 2000 and 2009 are represented in this dataset at the ten-minute square resolution. The purpose of this data product to show the relative concentration of recreational fishing effort for each ten-minute square by federally permitted party and charter fishing vessels.

  19. Title: Offshore Tidal Hydrokinetic Projects for United States Waters, June 2013

    Contributors:

    Summary: Pending or issued preliminary permits* or issued licenses for offshore hydrokinetic projects that produce energy from the flow of water in ocean currents or tides. The status of these projects is administered by the Federal Energy Regulatory Commission (FERC). This dataset excludes any sites considered inland. Listings found for maximum capacity and average annual production are estimates obtained from applications submitted to FERC by the licensee. Actual numbers upon build-out could vary. *Preliminary permits maintain priority of application for a license for up to three years while a potential license applicant explores project feasibility and prepares a license application, but do not authorize construction, operation, or maintenance of a hydropower project. While studies are often carried out while potential applicants hold preliminary permits, the permits do not authorize any activity or site access. Such permissions must be obtained from the appropriate authority. In some cases, potential license applicants can obtain a successive permit if they have pursued the preparation of a license application in good faith and with due diligence. Only a small portion of preliminary permits lead to licenses.

  20. Title: Energy Facilities Located 80km from the Northeast U.S. Coast, 2012

    Contributors:

    Summary: This point shapefile depicts the locations of facilities that generate electricity derived from the Environmental Protection Agency (EPA) Emissions and Generation Resource Integrated Database (eGRID) which is representative of 2009 facilities. Only facilities adjacent to the coast and Great Lakes are shown. Contained within the database are records that define the fuel source and other characteristics of the facility that may benefit ocean planners. In some cases, the presence of a facility may indicate that certain power transmission infrastructure exists nearby. Absence of a facility or lack of sufficient capacity at a facility in a given area may also be an important characteristic in future energy planning activities. Please keep in mind this is not representative of the whole eGRID. This dataset can be linked back to the additional content of the eGRID by downloading the data and joining it back to the eGRID spreadsheet using the File Plant Sequence Number field.
