The Core Research Center (CRC) was established in 1974 by the USGS to preserve valuable samples of the Earth’s subsurface for use by scientists and educators representing government, industry, and academia. The CRC collections include full-diameter rock cores, slabbed cores (cut in half longitudinally), well cuttings, thin sections, and associated analytical data. A majority of the material was donated to the CRC by private industrial companies, although some cores and cuttings were collected by the USGS and other government agencies. Rock cores were collected from roughly 9,500 drilled borehole locations representing approximately 610,000 meters (2 million feet) of subsurface strata in 35 states. Many of the boreholes...

The Arkansas Geological Survey (AGS) is the curator for the Norman F. Williams Well Sample Library and maintains well cuttings and core samples as a permanent record of rock strata that have been penetrated by wells drilled in Arkansas. Driller logs housed at the Survey contain the down hole information about the geology in the state. Each log gives the depth in feet along with the discription of material being drilled and the depth it accurs. The logs cover wells drilled in the early 1900’s to 1950’s and dispersed throughout the state giving statewide subsurface information.

Collections of physical samples and data managed and preserved by the U.S. Geological Survey (USGS). The separate collections are managed by different projects and Mission Areas of the USGS. The collections are distributed across the United States, in various USGS offices. Preservation of some of these collections may be supported by the National Geological and Geophysical Data Preservation Program. USGS strives to publicly expose its materials, data, and other research to further scientific inquiry. Points of contact for individual collections may be contacted to request access to materials and data.

The U.S. National Ice Core Laboratory (NICL) is a National Science Foundation (NSF) facility for storing, curating, and studying meteoric ice cores recovered from the glaciated regions of the world; mostly from Antarctica and Greenland. The NICL is funded by the NSF Division of Polar Programs and operated by the USGS; and the NICL’s science operations are managed by the University of New Hampshire. NICL provides scientists with the capability to conduct examinations and measurements on ice cores, and it preserves the integrity of these ice cores in a long-term repository for future investigations. The NICL was established in 1993 and is located at the Denver Federal Center, in Denver, Colorado. The NICL’s primary...

Since its inception in 1879, the USGS has collected and preserved geoscience data and sample collections, which include millions of paleobiological specimens stored in USGS facilities and at the Smithsonian Institution National Museum of Natural History (NMNH) in Washington, D.C. As one of the largest paleontological collections in the world, the USGS paleontology collection is invaluable, as many specimens may no longer be collected due to high field collection costs or inaccessibility to sampling sites, which have been restricted, urbanized, or modified via landscape processes. The USGS Denver Paleontology Collection includes ~1.2 million specimens stored in 1000 Smithsonian museum cases. The primary collections...

Library collection of 34 out-of-print Biennial Reports of the Commissioners of the State Geological and Natural History Survey to the Governor and State Legislature of Connecticut. These historic reports chronicle the legacy and evolution of the State Geological and Natural History Survey of Connecticut from its inception in 1903 until it became an entity of the state environmental agency in 1971. This collection include 682 pages of text, 18 figures, 9 plates, and 2 map sheets. These reports are valuable to science historians, academic scholars, geoscience professionals, and public policy experts. A related Connecticut Survey Library collection contains associated historic correspondence. Although most of the...
Shapefiles showing the extent of the Dugger, Minshall-Buffaloville, Seelyville, and Springfield Coal Members derived from coal-test records, mine-map notation, and interpretations of geophysical logs. Information was included in the USGS National Coal Resources Data System (NCRDS).

Since 2002, the Woods Hole Coastal and Marine Science Center’s Samples Repository has been supporting research by providing secure storage for geological, biological, and geochemical samples; maintaining organization and an active inventory of these sample collections; as well as by providing access to these collections for study and reuse. This collections inventory has been compiled, organized, and released online to provide researchers and the general public with a means to discover and request scientific sample material preserved and maintained by the Woods Hole Coastal and Marine Science Center Samples Repository. Updates will be made to the inventory as the collections grow, and version history is available...
