Related CMG Knowledge Management marine database sites Description
InfoBank, a field data catalog for the Coastal and Marine Geology Program (CMGP), is a structured information storage scheme of databases and software that provide organized access to USGS Coastal and Marine data and metadata. InfoBank consists of: 1) databases (collections of associated information), including metadata about field data collection activities, digital data from field data collection activities, analog materials from field data collection activities, and related information; 2) software that organizes and sorts the information; 3) Web interface that presents the information to users. Data are stored as ASCII text documents, Arc coverages, images, spreadsheets, and videos in structured Unix subdirectories. Fortran programs, Shell scripts, and AWK scripts used for formatting and processing the data are also stored in InfoBank. InfoBank may be searched using Google or other internet search engines. InfoBank-specific Google searching is provided within InfoBank. The data may be viewed using a web browser. Files may be copied using the browser's "save as" feature. Thematic collections of many geo-referenced data sets are provided as .kmz's for browsing with Google Earth. Metadata are provided in metadata standard version FGDC-STD-001-1998 format in faq, outline, text, and xml forms. Metadata may be accessed through the Web.
Coastalmap is the CMGP ArcIMS web server that displays project published GIS data to the public via HTTP. Data are compiled in 23 individual map views that are comprised of project specific (e.g. shoreline change, Long Island Sound, Monterey Bay or the Channel Islands region) or regional map views (e.g. U.S. Atlantic East Coast with GLORIA or usSEABED -- East Coast, Gulf of Mexico and Caribbean and West Coast). Currently coastalmap serves approximately 565 individual CMGP geospatial data layers. Example of data layers included within the map server are: sidescan sonar imagery, acoustic backscatter and bathymetric images, derived bathymetry contours, surficial sediment data, interpretations, navigation data, core locations and bottom photo locations. If available, some data layers, such as bottom photograph locations, include hyperlinks to the acquired photographs and may be viewed within the mapservice. The specific data available in any single map view will vary and is dependent on the data collected, produced and published by the individual project. All published data includes FGDC compliant metadata. Map views and data layers may be accessed via the public with any WWW browser, WMS client or ESRI ArcGIS software. Data are served as either shapefiles or GeoTIFF imagery in geographic.
Coastal and Seafloor Mapping
We conduct integrated mapping of the coastal and marine environment to define offshore hazards and sediment processes, support habitat and resource management, and monitor change. Learn about mapping systems, mapping technology, and our global activities.
LASED (Louisiana Sedimentary and Environmental Database) is the result of combined efforts of the USGS and academic collaborators to manage decades of geologic data from the Louisiana coastal zone. The database incorporates a wide range of data types (sediment-sample data, geophysical profiles, logbooks, etc) that are integrated with spatial data to provide processing and visualization capabilities using standard GIS and Internet-browsing tools. The public can access the database by using the LASED IMS. All data has FGDC compliant metadata and exist in a variety of formats including GIS shapefiles and coverages, ASCII text files, digital images and html formatted documents and websites. Data in the IMS are organized by topic or theme. A searchable catalog has not yet been implemented. Unique LASED supporting thematic data that might be relevant to the Multipurpose Marine Cadastre are: bathymetry, digitized fault locations, and geo-rectified historic Louisiana coastline atlas. In addition we have reference data on abandoned barges, refuge boundaries, oil and gas wells, pipelines, power lines, astronomical high tide line, wetlands, and sediment resources.
Law of the Sea database The Law of the Sea database currently consists of a single report available on CD-ROM entitled: A Preliminary Assessment of Geologic Framework and Sediment Thickness Studies Relevant to Prospective US Submission on Extended Continental Shelf by Deborah R. Hutchinson, Jonathan R. Childs, Erika Hammar-Klose, Shawn Dadisman, N. Terrence Edgar, and Ginger Barth. The report includes tables and maps indicating seismic reflection and refraction profile coverage over selected sedimentary basin areas within and adjacent to the US EEZ. These coverages have been exported to ArcGIS, currently unpublished.
Marine Realms Information Bank
   Coastal Change Hazards Digital Library
   Monterey Bay Science Digital Library
The Marine Realms Information Bank (MRIB) and its offshoots provide access to free online information for coastal and marine science. MRIB maintains searchable metadata records and hyperlinks for nearly 2,500 Internet resources: web sites, full-text reports, digital maps, and downloadable data. MRIB includes information from governmental agencies, academic institutions, nonprofit research centers, and other reputable sources. About 60 percent of the entries in MRIB are USGS products; 40 percent are specific to the Coastal and Marine Geology Program (CMGP). For topical searching MRIB employs twelve controlled-vocabulary facets (categories), including author, agency, discipline, project, feature type, content type, and file type. About 70 percent of the information resources in MRIB are also georeferenced for searching by geographic coordinates or named location. This metadata scheme would allow the user to find (for example) CMGP data publications about a particular location and/or physiographic setting by combining the appropriate search terms from the agency, feature type, and content type facets, along with geographic coordinates or a named location from the MRIB gazetteer. By including parameters from the discipline, project, and file type facets, the search could be narrowed even further. Having retrieved the desired metadata records, the user may export these records in a variety of formats, including XML, or link directly to the original online resources. The MRIB user interface is designed to facilitate manual searching, retrieval, and exporting of the metadata. However, a forthcoming handbook describing MRIB access protocols will allow these operations to be automated, so that other information systems can "mine" the MRIB database.
National Archive of Marine Seismic Surveys (NAMSS)
The National Archive of Marine Seismic Surveys (NAMSS) is a database of seismic reflection profile data within the US EEZ acquired from a variety of commercial and public sources. The data is searchable with Google Earth, but the data archives are stored in InfoBank. The search engine simply assists the user locate a survey of interest and directs them to the appropriate InfoBank site. All access and metadata protocols are handled by InfoBank. Data are in a variety of formats. Seismic reflection data are in SEG-Y format, one file per reflection profile or line; all SEG-Y files for a single survey are compressed into a single "tar" file for download. Shotpoint navigation are in flat ASCII format. Other ancillary data may be available as ASCII text, pdf or tiff files.
National Seafloor Mapping and Benthic Habitat Studies
Accurate base maps are a prerequisite for any geological study, regardless of the objectives. Land-based studies commonly utilize aerial photographs, USGS 7.5-minute quadrangle maps, and satellite images as base maps. Until now, studies that involve the ocean floor have been at a disadvantage due to an almost complete lack of accurate marine base maps. Many base maps of the sea floor have been constructed over the past century but with a wide range in navigational and depth accuracies. Only in the past few years has marine navigational accuracy approached 1 m and depth resolution 50 cm. State-of-the-art digital multibeam systems are used to systematically map the seafloor. The two types of data collected include bathymetry (seafloor depth) and backscatter (data that can provide insight into the geologic makeup of the seafloor). These data are of critical importance to groups as diverse as marine habitat biologists, state and local authorities setting regulations on seafloor uses, school children, and teachers. The new high-resolution base maps will be used for: identifying areas of erosion and deposition on the continental shelf; locating areas of geohazards (such as slumps and faults); locating pathways for movement of sediment and pollutants.
Tampa Bay Data and Information Management System
The Tampa Bay Data and Information Management System (DIMS) contains digital products and data on the Tampa Bay estuary and watershed. The three main components are a Web site, digital library, and Internet Mapping System (IMS). Spatial data are stored in both the IMS and digital library. Data in stored in various formats, although spatial data is predominately in ESRI shapefile, ERDAS imagine, or geotiff format. All data are downloadable as zips with files and metadata, except where file size exceeds our desire to provide as a downloadable data set. Currently, we do not have OGC Web Map Services for the IMS, but plan to begin these services in the near future. Metadata is FGDC compliant and is available in XML, HTML, or text format. Metadata is contained within the digital library as a product type and can be sorted and obtained via the library.
usSEABED is a nation-wide seabed characteristic database that includes textural, statistical, and constituent information as well as selected geochemical and geophysical parameters. These numeric, sited data are both from lab-based analyses and word-based descriptions through the application of fuzzy set theory to linguistics, and represent the work of the USGS, other Federal agencies, State and local agencies and consortia, universities and other marine-focused groups. Currently usSEABED holds information for over 300,000 sites around the United States which is published through the USGS Data Series publications. Technical requirements for usSEABED are few; they are published both as GIS shapefiles and as comma-delimited text files, which can be used in many modeling softwares.
Woods Hole Data Archive
The online archives of the Woods Hole Data Archive include multiple indexes (Field Activity, Time Series Data, Field Photograph) for different types of data, all linked to Woods Hole field activities.
WHSC Field Activity Archive
WHSC Field Activity Archive contains descriptions, metadata, on-line data resources, off-line data resources, and links to publications or GIS resources for all field activities conducted by our field center from 1965 to the present. All types of data are available. Most seismic data is available as SEG-Y or as a tiff image of scanned paper records. Navigation is available as text files using a variety of different formats. Other magnetic and gravity data is available as text files. All field activity information is stored in multiple databases, which can be searched on the web. In addition web pages are generated nightly for each field activity so that this archive is searchable via other search engines such as Google. Field activity metadata is stored as text files using the FGDC format. These metadata files only include information covering the acquisition of the data and not the data processing. These could be searched, but the database search functions cover the same information and are much faster.
WHSC Time Series Data Archive
WHSC Time Series Data Archive contains the raw times series data collected by this field center from 1977 to the present. Data is available as netCDF formatted files. The server has several methods for accessing the data. The binary data is available using the DODs OpenDAP framework, which allows users to port data directly into their applications. There is also a THREDDS Aggregation server ( which can make data available by combining and spanning multiple data sets. Web pages for each experiment have been created that describes the contents of the data files, experiment descriptions, and links to publications and field activities. These pages are searchable via other search engines such as Google. Access to these data can also be gained using the search capabilities of the WHSC field activity Archive. Metadata is stored in each data file as part of the netCDF header information. This metadata is currently not searchable, but information from the metadata is on the experiment web pages that can be searched.
WHSC Field Photograph Archive
WHSC Field Photograph Archive contains photographs taken during WHSC field operations from 1975 to the present. All photographs are available in JPG format. Access to these photographs is through a web searchable database that is connected to the WHSC Field Activity Archive. Metadata for each photograph is recorded in the Extensis Portfolio database in a proprietary format.
WHSC public Web server
WHSC public Web server contains data publications with data files. The format of the data varies with each publication and data type. Most publications have GIS data as well. This data is searchable on our ArcIMS system Coastalmap. Metadata is FGDC format in text, html, and XML files. These files are not used for searching. The main mechanism for searching is through the publications warehouse and through links from the WHSC Field Activity Archive and the ArcIMS server.
