Title:
Index to Marine and Lacustrine Geological Samples (IMLGS)
Dataset Publication Date:
1977-12-31
Abstract:
The Index to Marine and Lacustrine Geological Samples (IMLGS) contains inventory and basic lithology, texture, and age information for geologic samples of sediment and rock from the seafloor and lakebeds archived by approximately twenty oceanographic institutions and government agencies, in the U.S., Canada, the United Kingdom, and Germany. Most samples are available for further study, on request from the individual repository. Listings from the file include institutional contact information. Data are coded at the curatorial facility and include ship, cruise, sample id, latitude/longitude, water depth, date of sample collection, sampling device, storage method, core diameter/length and interval within core (if applicable). Sample descriptions, including primary and secondary lithology and texture or rock type and mineralogy, other noted components, remarks and weathering notes, age, province, principal investigator, and descriptive comments are included for some samples, all samples include basic collection information. The IMLGS includes over 500,000 data records containing information for over 197,000 discrete sea floor and lakebed cores, grabs, dredges, and drill holes worldwide, as of January 2013. The IMLGS is searchable by any parameter or combination of parameters. The database was designed by representatives of the curatorial facilities in cooperation with NGDC through a series of meetings sponsored by the National Science Foundation (NSF), beginning in 1977, and NSF continues to support coding of data into the Index. The Index is accessible via a Web Feature Service (WFS), a Web Map Service (WMS), a www-forms interface, and a geospatially-enabled ArcGIS interactive map interface.
