Count Component Title Abstract
1 Index to Marine and Lacustrine Geological Samples (IMLGS) 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. Material from most samples may be requested from the responsible Curator for scientific research, using contact information provided in IMLGS data listings. Each curatorial facility prepares data on their own collection for the IMLGS. Minimum information includes platform, cruise, 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, weathering information, and geologic age are included for some samples. An International GeoSample Identifiers (IGSN) is included, where known. Links are 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 includes information about over 207,935 discrete sea floor and lakebed cores, grabs, dredges, and drill holes worldwide, as of December 7, 2015. The database was 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 biennially to share best practices and oversee the IMLGS database.

1 facility_code An abbreviation for the sample repository responsible for curating a given marine or lacustrine geological sample.
1 ship_code A deprecated four-digit numeric code. The first two digits are an institution code and the second two digits are a unique ship within the institution. This code is internal to NCEI and specific to marine geology.
1 platform The name of the platform (usually a ship) that collected the geological sample.
1 cruise The period of operation of a ship, during which a geological sample was taken. A cruise may contain one or more legs, or port-to-port segments.
1 sample The sample may be geologic material recovered by a single grab, dredge, or core, or may indicate a single hole in the sea floor or lakebed. Within a hole/sample, there may be additional distinct down-hole cores, sections, or intervals.
1 device The type of device used to recover a geologic sample from the sea floor or a lakebed.
1 ns Indicator of whether latitude is north or south of the equator.

1 ew Indicator of whether longitude is east or west of the Prime Meridian.
1 end_ew Indicator of whether longitude is east or west of the Prime Meridian, at which sampling operations were concluded. Blank if sampling location is fixed.
