The purpose of compiling the CEUS-SSC Project database was to organize and store those data and resources that had been carefully and thoroughly collected and described for the TI Team’s use in characterizing potential seismic sources in the CEUS. An important goal for the development of this database was to document sources and dates for all information that was initially assessed for the CEUS-SSC Project, specifying exactly what data and resources were considered, and provide for pertinent future data sets to be incorporated as they were generated for the project. Development of the project database began at the inception of the project to provide TI Team members with a common set of data, maps, and figures for characterization of potential seismic sources. The database was continually updated during the course of the project through the addition of new references and data collected by TI Team members and project subcontractors, including information presented in project workshops and provided through PPRP review documentation. This appendix presents the contents of the project database, as well as information on the workflow, development roles, database design considerations, data assessment tasks, and management of the database. Based on the CEUS Project Plan, the project database included, but was not limited to, the following general types of data: Magnetic anomaly Gravity anomaly Crystalline basement geology Tectonic features and tectonic/crustal domains Tectonic stress field Thickness of sediments Crustal thickness VP at top of crystalline basement Seismic reflection data at Charleston, South Carolina Earthquake catalog Quaternary faulting and potential Quaternary features Mesozoic rift basins Paleoliquefaction sites Topography and bathymetry Liquefaction dates from published literature for the Wabash, New Madrid, and Charleston seismic zones Index map showing locations of published crustal scale seismic profiles and geologic cross sections

Abstract:The Australian Bathymetry and Topography web service includes the topography of Australia and the bathymetry of the adjoining Australian Exclusive Economic Zone. The area selected does not include data from Australia's marine jurisdiction offshore from the Territory of Heard and McDonald Islands and the Australian Antarctic Territory. The 2009 bathymetry data were compiled by Geoscience Australia from multibeam and single beam data, and along with the topography (onshore) data, was derived from multiple sources. As per the 2005 grid, the 0.0025 dd resolution is only supported where direct bathymetric observations are sufficiently dense (e.g. where swath bathymetry data or digitised chart data exist) (Webster and Petkovic, 2005). In areas where no sounding data are available (in waters off the Australian shelf), the grid is based on the 2 arc minute ETOPO (Smith and Sandwell, 1997) and 1 arc minute ETOPO (Amante and Eakins, 2008) satellite derived bathymetry. The topographic data (onshore data) is based on the revised Australian 0.0025dd topography grid (Geoscience Australia, 2008), the 0.0025dd New Zealand topography grid (Geographx, 2008) and the 90m SRTM DEM (Jarvis et al, 2008).© Commonwealth of Australia (Geoscience Australia) 2016.Downloads and Links:Web ServicesAustralian Bathymetry and Topography Grid, June 2009 WCSAustralian Bathymetry and Topography Grid, June 2009 WMSAustralian Bathymetry and Topography Grid, June 2009 MapServer Downloads available from the expanded catalogue link, belowMetadata URL:https://pid.geoscience.gov.au/dataset/ga/67703

GEBCO’s current gridded bathymetric data set, the GEBCO_2023 Grid, is a global terrain model for ocean and land, providing elevation data, in meters, on a 15 arc-second interval grid. It is accompanied by a Type Identifier (TID) Grid that gives information on the types of source data that the GEBCO_2023 Grid is based on. This release includes a version of the grid with under-ice topography/bathymetry information for Greenland and Antarctica.

This GIS layer contains bathymetric elevation bands (derived from bathymetric contours) of selected freshwater lakes in Washington State. The majority of the bathymetric contours were digitized from maps contained in a series of seven documents: Reconnaissance Data on Lakes in Washington, Water-Supply Bulletin 43, Volume 1 through 7 by the United States Geological Survey in cooperation with the Washington State Department of Ecology. The exceptions are 1) Lake Chelan which was digitized in 2016 from the publication Morphometry of Lake Chelan (published in January 1987); 2) Lake Sammamish whose digital data was acquired from King County in 2013 and is derived from data collected during the publication of Development of a Three-Dimensional Hydrographic Model of Lake Sammamish (published in November 2008); and 3) Lake Crescent, whose digital bathymetric soundings were taken by a private party during 2013/2014 and provided to the Department of Ecology and were converted to contour lines in 2016.

Bathymetry is the measurement of the depth of large bodies of water. Bathymetry data can be stored in a number of formats including point soundings, isobaths (contours), and grids. The bathymetry mosaic dataset is a grid coverage of water depth generated from point soundings. The grid structure is a regular array of cells referenced to the Universal Transverse Mercator (UTM) coordinate system. Each grid cell represents water depth for a discrete 20- x 20-meter area. The mosaic is a continuous grid covering Washington marine waters, Oregon waters as far south as Seaside, and the Columbia River upstream to Bonneville Dam. Canadian marine waters are included for southern Vancouver Island. The dataset was funded by the Puget Sound Ambient Monitoring Program (PSAMP). Primary bathymetry grid processing was performed under contract by Environmental Consultants (ECI), Portland, Oregon.

NGDC's Vision is to be the world's leading provider of geophysical and environmental data, information, and products. The National Geophysical Data Center (NGDC), located in Boulder, Colorado, is a part of the US Department of Commerce (USDOC), National Oceanic & Atmospheric Administration (NOAA), National Environmental Satellite, Data and Information Service (NESDIS). We are one of three NOAA National Data Centers. NGDC's Mission is to provide long-term scientific data stewardship for the Nation's geophysical data, ensuring quality, integrity, and accessibility. NGDC provides stewardship, products and services for geophysical data describing the solid earth, marine, and solar-terrestrial environment, as well as earth observations from space. NGDC's data holdings currently contain more than 400 digital and analog databases, some of which are very large. As technology advances, so does the search for more efficient ways of preserving these data. NGDC works closely with contributors of scientific data to prepare documented, reliable data sets. We welcome cooperative projects with other government agencies, nonprofit organizations, and universities, and encourage data exchange.
