IMLGS

Index to Marine & Lacustrine Geological Samples

Initiative Type: Infrastructures

Belém Statement Area: Ocean Observation

Initiative Location: United States of America

Time Frame: 1977-Ongoing

Description:

The Index to Marine and Lacustrine Geological Samples (IMLGS) is a tool to help scientists locate and obtain geologic material from sea floor and lakebed cores, grabs, and dredges archived by participating institutions around the world. Data and images related to the samples are prepared and contributed by the institutions for access via the IMLGS and long-term archive at NGDC. Data include basic collection and storage information. Lithology, texture, age, principal investigator, province, weathering, metamorphism, glass remarks, and descriptive data are included for some samples, at the discretion of the curator. The Index provides links to view and download related data and images in the long-term archive, at participating institutions, and includes reciprocal links to the National Science Foundation (NSF) sponsored Rolling Deck to Repository (R2R). R2R also maintains a Linked Data version of the IMLGS in cooperation with NOAA. Several thousand samples in the Index also link to the NSF supported System for Solid Earth SAmple Registration (SESAR) by IGSN, the Marine Geoscience Data System (MGDS) and PetDB. The Index is endorsed by the Intergovernmental Oceanographic Commission, Committee on International Oceanographic Data and Information Exchange (IODE-XIV.2). Look for data from the Index to Marine and Lacustrine Geological Samples, and for data digitized under the NOAA Climate Database Modernization Program (CDMP), in the NSF-funded GeoMapApp, and in the GRID-Arendal Continental Shelf Programme.
