The IMLGS is a collaboration between NCEI and multiple institutions (some supported by NSF) and government agencies, created by the institutions to offer common data about, and discovery/access to geological samples in their sample repository collections. The purpose of the IMLGS is to promote new research on existing samples. The database is maintained by NCEI under the guidance of a Curators Consortium, composed of representatives from the partner institutions. Geological samples collected as part of the U.S. Extended Continental Shelf (ECS) Project are curated by the U.S. Geological Survey, a partner in the ECS Project. To date, dredges and cores have been collected from the Arctic Ocean floor, and small sediment samples have also been collected from the Bering Sea. According to ECS policy, application can be made by qualified researchers to the ECS Samples Curator to obtain portions of these samples for study. Related sample data, information, and images generated at sea, during ECS post-cruise working parties, and other research results are available for public access via the ECS Information Management System (ECS IMS) website maintained by NOAA's NCEI. Both ECS samples and related data are searchable through the Index to Marine and Lacustrine Geological Samples (IMLGS) database maintained by NCEI. The first priority for geologic samples collected as part of the U.S. ECS Project is their application to delineating the U.S. ECS, however the ECS Task Force recognizes the important scientific value of these samples and encourages their study and the open publication of related scientific findings. The purpose of adding information about the ECS geological samples collection to the IMLGS is to promote new research on existing samples. Samples were collected as part of the interagency ECS Project. onGoing historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information pointOfContact NOAA National Centers for Environmental Information Marine Geology Data Manager 325 Broadway, Mail Code E/NE42 Boulder CO 80305-3328 USA geology.info@noaa.gov pointOfContact irregular ECS core data are collected infrequently, no new samples have been collected since 2012. https://www.ngdc.noaa.gov/mgg/image/ECSsampleLocations.png image of sea floor sample locations PNG Databases Scientific archives Electronic records Ocean bottom Geology Submarine geology Marine sediments theme Library of Congress Subject Headings US Library of Congress http://id.loc.gov/authorities/subjects http web browser Library of Congress Subject Headings (LCSH) The Library of Congress Subject Headings (LCSH) are part of a Linked Data Service, actively maintained since 1898 to catalog materials held at the Library of Congress. information resourceProvider Marine geology Rock and sediment lithology and mineralogy theme SeaDataNet Common Vocabularies SeaDataNet http://www.seadatanet.org/Standards-Software/Common-Vocabularies http web browser SeaDataNet Common Vocabularies The SeaDataNet Vocabulary Server is populated with lists describing a wide range of entities relevant to marine metadata and data such as parameters, sea area names, platform classes, instrument types, and so on. information resourceProvider Sea-floor characteristics theme USGS Science Topics US Geological Survey https://www2.usgs.gov/science/about/ http web browser USGS Thesaurus The USGS Thesaurus contains thematic terms for categorizing information resources intended to support finding and understanding scientific information. information resourceProvider Earth Science > Oceans > Marine Sediments Earth Science > Oceans > Marine Sediments > Sediment Composition theme Global Change Master Directory (GCMD) Science Keywords 2024 revision 19 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2024.

All samples collected between 2008 and 2012 are represented in the IMLGS. NCEI works with the partner institutions to ensure that sample data published in the IMLGS conforms to agreed upon formats and vocabularies, but cannot guarantee the accuracy of the information itself. Horizontal Positional Accuracy The horizontal accuracy of data values is approximately .001 degree of latitude/longitude. Reliability Quality control was performed by the ECS Samples Curator at the USGS and also in coordination with NCEI after data submission. Numeric data are subjected to out of range testing at NCEI, then posted on a test web site for inspection by the originator. Data are iteratively corrected at NCEI until the originator approves their publication to the production database. Incoming data were checked for adherence to controlled vocabularies, illegal data types in numeric fields, and out of range latitudes/longitudes. NCEI added IGSNs/links to related resources, where known, and performed cursory visual inspection of data for reasonableness, asking the originator for guidance on discrepancies. Approximate date the first data were received from this repository. 2008-12-31T00:00:00 Carla J.
