This collection is comprised of digital, slide and print photographs taken during engineering geology, energy and minerals resource related field projects from 1970-2020. These photos document field sites, geologic features, landscapes and landforms from the various areas of Alaska. There are collections specific to each of the Division's sections that document the effort needed to complete the culling and documentation of exisiting photos. As of 2020, DGGS has cataloged 19,724 photos, with 12,813 available to the public. Only those photos with location information are available within the National Digital Catalog

This collection currently contains approximately 24,000 oil- and gas- related surface samples, which is a subset of the 507,000 surface samples housed at the Alaska Geologic Materials Center. The Amoco Heritage Collection was donated by Amoco-BP in 2002 and contains samples from fieldwork conducted from 1960-1990 in high energy-resource-potential areas of Alaska.
This collection is comprised of legacy DGGS geologic maps that have been converted to the single-map USGS Geologic Map Schema (GeMS; formerly known as NCGMP09). Initial conversions will be conducted on maps in areas with critical mineral potential, benefiting DGGS and USGS critical mineral studies in Alaska. Future additions to this collection will include both converted geologic maps, and new geologic maps created using the GeMS schema.

The Alaska Division of Geological and Geophysical Surveys (DGGS) surface sample collection consists mostly of hand samples collected during projects involving DGGS geologists, but also includes pulps and residues. The accuracy of the sample metadata differs based on the time frame of the project that originated the samples. The DGGS projects fall in two categories: (1) legacy projects where sample locality information was not recorded systematically in either a physical or digital format and (2) recent and current projects where sample locality information has been recorded in digital databases. This collection consists of 123,808 rock samples as of 2020, though not all are accessible to the public or have location...

This sample collection consists of a 1997 donation from the Shell Oil Company to the Alaska Geological Materials Center. It contains approximately 68,000 samples of following types: dart (short seafloor cores), seismic shothole, outcrop, and megafossils. 80% of the collection are outcrop samples. 5 percent of the collection has been inventoried with specific locations. Most of the collection is in good shape though many megafossil sample bags need to be replaced. The remainder of the collection will be inventoried in a future data preservation project
This collection is comprised of digital, slide and print photographs taken during energy resource related field projects from 1970-2020. The majority of the individual items associated with this collection are field photos taken by Charles (Gil) Mull and Rocky Reifenstuhl. These photos document field sites, geologic features, landscapes and landforms from the various areas of Alaska. There are approximately 43,000 photos and slides that still need to be culled, documented and archived. 98% of the photos are in digital format and need to be manually matched with their locations from geologists' field notes. The remaining 2% are slide and print format that need the same attention but are in fair to good condition.

This collection consists of samples with age data and associated information for available radiometric dates for rocks and minerals in Alaska. The sample records and their associated publications were loaded into the Alaska Division of Geological and Geophysical Surveys division-wide database. A legacy Microsoft Access database exists that includes dates for all available U-Pb, K-Ar, 40Ar/39Ar, and Rb-Sr data for Alaska through 2007. Previous compilations by Wilson and others (1990) and U.S. Geological Survey (1999) provided the initial source of age data. Additional radiometric dates were compiled from both published and unpublished sources. This legacy project added essential basic supporting information that...
