Index to Marine and Lacustrine Geological Samples Database (IMLGS)
This database is a collaboration between multiple institutions and government agencies, some of which are supported by the National Science Foundation to participate. The database is managed by NCEI on behalf of the Curators Consortium of representatives from these institutions.
The Index to Marine and Lacustrine Geological Samples (IMLGS) describes and provides access to ocean floor and lakebed rock and sediment samples curated by participating institutional and government repositories in the U.S., Canada, the United Kingdom, France, and Germany. Each curatorial facility prepares and submits data about their own collection to NCEI for inclusion in the IMLGS. NCEI, on behalf of the Curator community, maintains the IMLGS database and a dedicated web application for data discovery and access. Physical material from most samples may be requested from the responsible Curator for scientific research using contact information provided in IMLGS data listings. As of July 2023, the IMLGS includes information for 228,785 discrete seabed and lakebed cores, grabs, dredges, and drill holes worldwide.
Minimum sample information required for the IMLGS includes ship/platform name, cruise ID, sample ID, sampling device, and latitude/longitude. Water depth, collection date, storage method, and principal investigator are usually included. Core dimensions and depth to top and bottom of interval is available for many core samples. Descriptions, comments, physiographic province, lithology, texture, mineralogy, other components, glass remarks, metamorphism information, weathering information, color, and geologic age are included for some samples. An International Generic Sample Number (IGSN) is included, if available. Links are also provided to related data and images at NCEI, partner institutions, and to other sources of information including the System for Earth SAmple Registration (SESAR) and the Rolling Deck to Repository (R2R).
The IMLGS database was initially designed by a group of Curators, in cooperation with NGDC (now NCEI), at a series of meetings sponsored by the U.S. National Science Foundation (NSF) beginning in 1977. The Curators group continues to meet annually to share best practices and oversee the IMLGS database.
The purpose of the IMLGS is to promote new research on existing seabed and lakebed cores, grabs, dredges, and drill samples by helping researchers find existing samples curated by participating geosample repositories. Geosamples are invaluable cross-disciplinary resources. Their uses include, but are not limited to, understanding past climate change, assessing benthic habitat for fish and other biological communities, assessing offshore pollution patterns, assessing the impacts of offshore geohazards, determining suitable sites for offshore infrastructure (e.g., wind turbines), finding suitable sediment for coastal restoration, locating strategic offshore mineral resources, ground-truthing acoustic and other remotely-sensed mapping data, and learning more about other Earth systems and processes.

The Index to Marine and Lacustrine Geological Samples Map Service provided by the NOAA National Centers for Environmental Information is an ArcGIS map service providing access to metadata, data, and images about seafloor and lakebed cores, grabs, and dredge samples (sediment and rock) curated by and available from participating institutions. Samples are color-coded by participating institution. The dynamic map service is is visible at all scales, and allows subsets of the data to be drawn using a layer definition query. The corresponding tiled (cached) service is quicker to draw but only visible from global scales up to zoom level 8 (approx. 1:2,300,000 scale). The tiled map service is also available in an Arctic projection.

dataset
gov.noaa.ngdc.mgg.geology:G00028
Samples are continuously added to the collections of participating repositories. Completeness of data in the IMLGS for each collection is determined by submission schedule of the individual repository.
Some recently collected samples are still in process by the participating repositories and will be published as they are submitted for inclusion 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 is performed by originator 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.
Data are received by NCEI on a continuing basis from the participating repositories. Incoming data are checked for adherence to controlled vocabularies, illegal data types in numeric fields, and out of range latitudes/longitudes. NCEI adds IGSNs/links to related resources, where known, and may perform cursory visual inspection of data for reasonableness, asking the originator for guidance on discrepancies. NCEI informs the originator upon ingest of data to the IMLGS database, after which the originator provides one final quality control using the IMLGS map viewer. Data may also be updated/corrected at any time, at the originator's request.
