Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    C-53, Geologic Atlas of Steele County, Minnesota
    (Minnesota Geological Survey, 2022) Retzler, Andrew; Mayer, Jordan; Bradley, Margeurite; Nguyen, Maurice; Marshall, Katherine; Conrad, Daniel; Lively, R. S.
    A County Geologic Atlas project is a study of a county's geology, and its mineral and ground-water resources. The information collected during the project is used to develop maps, data-base files, and reports. This same information is also produced as digital files for use with computers. The map information is formatted as geographic information system (GIS) files with associated data bases. The maps and reports are also reproduced as portable document files (PDFs) that can be opened on virtually any computer using the free Acrobat Reader from Adobe.com.

    OFR18-03, Core Descriptions, Borehole Geophysics, and Unit Interpretations in Support of Phase I and II USGS Hydrologic Properties of Till Investigation
    (Minnesota Geological Survey, 2018) Staley, Amie E; Wagner, Kaleb; Nguyen, Maurice; Tipping, Robert
    This report summarizes the contributions of the Minnesota Geological Survey (MGS) to a three-year study conducted in two phases – Environmental and Natural Resources Trust Fund (ENRTF), M.L. 2014, Chp. 226, Sec. 2, Subd. 03h, and ENTRF, M.L. 2016, Chp. 186, Sec. 2, Subd. 04h, led by the United States Geological Survey (USGS) Minnesota Water Science Center, which seeks to further knowledge on the sources and rates of recharge to confined aquifers set within buried-valley sequences in Minnesota. Six cores (including one collected for a previous study) of unconsolidated Quaternary deposits were extracted from known confined glacial aquifer settings, in four regions across Minnesota, in order to target variability in the material properties of the aquitards that confine them.
