| USGS CMG InfoBank
http://walrus.wr.usgs.gov/infobank/ |
InfoBank, KnowledgeBank's field data catalog,
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
http://coastalmap.marine.usgs.gov/ |
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.

| LASED IMS
http://coastal.er.usgs.gov/lased/ |
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
http://mrib.usgs.gov/
Coastal Change Hazards Digital Library
http://mrib.usgs.gov/cch/
Monterey Bay Science Digital Library
http://mrib.usgs.gov/mbs/ |
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)
http://walrus.wr.usgs.gov/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
http://walrus.wr.usgs.gov/pacmaps/ |
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
http://gulfsci.usgs.gov/tampabay |
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
http://walrus.wr.usgs.gov/mapping/usseabed.html |
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. |

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
http://woodshole.er.usgs.gov/operations/ia/ |
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
http://stellwagen.er.usgs.gov/ |
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
(http://coast-enviro.er.usgs.gov/)
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
http://nantucket.er.usgs.gov/ |
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
http://woodshole.er.usgs.gov/pubs/ |
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.
