This collection is comprised of digital, slide and print photographs taken during minerals related field projects from 1970-2020. There are approximately 35,800 photos and slides that need to be culled, documented and archived. 81% of the photos are in digital format and most need to be manually matched with their locations from geologists’ field notes, although a small percentage have locations and descriptions that could easily be archived. The remaining 19% are slide and print format that need the same attention but are in fair to good condition for scanning purposes. There are 50 videos that are also part of this collection. These photos document field sites, geologic features, landscapes and landforms from...

A full catalog of geoscience publications released by the Alaska Division of Geological & Geophysical Surveys. This includes all Alaska-related scientific reports, maps, and geospatial datasets. It excludes administrative reports, posters and presentations, newsletters, GMC data reports, brochures and pamphlets for the general public and publications that have been superseded.

The Utah Geological Survey (UGS) Geologic Map Database (MAPBIB) contains an inventory of approximately 2850 geologic maps covering various parts of Utah, that date from about 1890 to present, and that vary from formally published USGS and UGS Map and Bulletin Series maps, to informal consulting reports and internal unpublished ?sketch? maps. About half of these maps were published in production runs in which hundreds of copies were printed ? most of these maps are still widely distributed and readily available. However, over 1000 of the maps in our MAPBIB database were produced in only very limited numbers, are completely out of print, are in obscure or remote libraries, or are limited-distribution ?gray? literature...

The NJ Ambient Ground Water Quality Monitoring Network is a 150 monitoring well network designed to evaluate the status of and trends in shallow ground-water as a function of land use related non-point source contamination. Ambient Ground-Water Quality Monitoring Network Data This network is the only statewide shallow ground-water network in New Jersey that characterizes non-point impacts as a function of land use.

Minnesota Geological Survey (MGS) aeromagnetic data were acquired during a 1979-1991 statewide survey program, and were completely re-processed in 2005/2007 to recover line data that was missing from the primary archive at the National Geophysical Data Center, to improve line-leveling errors in the data, and to re-grid the data.

This collection includes records for non-water wells in Indiana. Some County Strat Test (CST) wells are pretty shallow boreholes located within the state. Most are related to petroleum exploration and development efforts. Data includes completion reports, scout tickets, geophysical logs, sample descriptions and test results. Some records include small-scale geophysical and colored driller's logs. This collection is housed in the Records Center at the Indiana Geological and Water Survey, Indiana University, Bloomington, and is accessible by appointment.

Samples are collected by MGS staff at outcrops, from auger drill holes, and rotary sonic drill holes. Samples are processed by student technicians to determine sample texture (% gravel, sand, silt, and clay). Approximately 100-150 grams of original sample is stored in a packet along with subpackets of the gravel fraction, 1-2 mm sand fraction, and <2 mm sand fraction. All lab data are recorded on paper lab sheets stored in the lab. Technicians also enter data into the MGS lithological database. Grain count analyses have been completed by glacial geologists on somewhere between 25 and 50% of these samples. These results are also recorded on paper sheets and in the database.
