Overview This directory was developed to provide discovery information for anyone looking for publicly accessible repositories that house geological materials in the U.S. and Canada. In addition, this resource is intended to be a tool to facilitate a community of practice. The need for the directory was identified during planning for and follow-up from a drill core repository webinar series in Spring 2020 for public repository curators and staff in the U.S. and Canada hosted by the Minnesota Geological Survey and the Minnesota Department of Natural Resources. Additional supporting sponsors included the U.S. Geological Survey National Geological and Geophysical Data Preservation Program and the Association of American State Geologists Data Preservation Committee. The 10-part webinar series provided overviews of state, provincial, territorial, and national repositories that house drill core, other geoscience materials, and data. When the series concluded a small working group of the participants continued to meet to facilitate the development and production of a directory of repositories that maintain publicly-accessible geological materials throughout the U.S. and Canada. The group used previous directory efforts described in the next section, Summary of Historical Repository Directory Compilation Efforts, as guides for content during development. The working group prepared and compiled responses from a call for repository information and characterization. This directory is planned to be a living resource for the geoscience community with updates every other year to accommodate changes. The updates will facilitated through versioned updates of this data release. Summary of Historical Repository Directory Compilation Efforts 1957 – Sample and Core Repositories of the United States, Alaska, and Canada. Published by AAPG. Committee on Preservation of Samples and Cores. 13 members from industry, academia, and government. 1977 – Well-Sample and Core Repositories of the Unites States and Canada, C.K. Fisher; M.P. Krupa, USGS Open file report 77-567.USGS wanted to update the original index. Includes a map showing core repositories by “State” “University” “Commercial” and “Federal”. Also includes a “Brief Statement of Requirements for the Preservation of Subsurface Material and Data” and referral to state regulations for details on preserved materials. 1984 - Nonprofit Sample and Core Repositories Open to the Public in the United States – USGS Circular 942. James Schmoker, Thomas Michalski, Patricia Worl. The survey was conducted by a questionnaire mailed to repository curators. Information on additions, corrections, and deletions to earlier (1957,1977) directories from state geologists, each state office of the Water Resources Division of the U.S. Geological Survey, additional government agencies and colleagues were also used. 1997 - The National Directory of Geoscience Data Repositories, edited by Nicholas H. Claudy – American Geologic Institute. To prepare the directory, questionnaires were mailed to state geologists, more than 60 geological societies, private-sector data centers selected from oil and gas directories, and to the membership committee of the American Association of Petroleum Geologists, one of AGI's member societies. The directory contains 124 repository listings, organized alphabetically by state. 2002 – National Research Council 2002. Geoscience Data and Collections: National resources in Peril.

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

The U.S. Geological Survey Coastal and Marine Geology Program (CMGP) Pacific Coastal and Marine Science Center (PCMSC) Samples Repository is a partner in the Index to Marine and Lacustrine Geological Samples (IMLGS) database. The Curator sends data and information related to the PCMSC marine geological sample collection to NCEI to increase their discoverability via the IMLGS. Selected data, documents, and images related to the collection are also archived at NCEI and discoverable via the IMLGS, but the USGS is the authoritative source for all data and information related to USGS geological samples.

This GIS dataset offers a link to the California portion of the Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey. The NAS program has been established as a central repository for accurate and spatially referenced biogeographic accounts of nonindigenous aquatic species. The program provides scientic reports, online/realtime queries, spatial data sets, regional contact lists, and general information. The goal of the information system is to provide timely, reliable data about the presence and distribution of nonindigenous aquatic species. The NAS database contains locality information for more than 1100 species of vertebrates, invertebrates, and vascular plants. The NAS program provides a continual national repository of distribution information for nonindigenous aquatic species that is used to gain an understanding of aquatic introductions, identify geographic gaps, and access the status of introduced aquatic species nationwide. Data are obtained from many sources including literature, museums, databases, monitoring programs, state and federal agencies, professional communications, online reporting forms, and Aquatic Nuisance Species (ANS) hotline reports. The NAS program defines a nonindigenous aquatic species as a member(s) of a species that enters a body of water of aquatic ecosystem outside of its historic or native range. This includes not only species that arrived from outside of North America but also species native to North America that have been introduced to drainages outside their ranges within the country. Please visit http://nas.er.usgs.gov for more information and to see all of the products and data available through the NAS program.

Well data for the USGS-142 well located in eastern Snake River Plain, Idaho. This data collection includes lithology reports, borehole logs, and photos of rhyolite core samples.

This collection of data has been assembled as part of the site characterization data used to develop the conceptual geologic model for the Snake River Plain site in Idaho, as part of phase 1 of the Frontier Observatory for Research in Geothermal Energy (FORGE) initiative. They were assembled by the Snake River Geothermal Consortium (SRGC), a team of collaborators that includes members from national laboratories, universities, industry, and federal agencies, lead by the Idaho National Laboratory (INL).

The Geographic Names Information System (GNIS) is the Federal standard for geographic nomenclature. The U.S. Geological Survey developed the GNIS for the U.S. Board on Geographic Names, a Federal inter-agency body chartered by public law to maintain uniform feature name usage throughout the Government and to promulgate standard names to the public. The GNIS is the official repository of domestic geographic names data; the official vehicle for geographic names use by all departments of the Federal Government; and the source for applying geographic names to Federal electronic and printed products of all types. See https://geonames.usgs.gov for additional information.

Cone Penetration Test (CPT) data collected by the U.S. Geological Survey since 1978 are compiled and provided as a uniformly formatted set of comma separated value (.csv) files. This dataset includes 1822 CPT soundings from 14 U.S. States. Provided CPT data are a set of three column comma separated value (.csv) files containing depth (meters), tip resistance (̨MPa), and sleeve resistance (kPa) measurements. All data are presented with no post processing or filtering applied. A separate index file contains the site names, positions, elevation, water table depth (if measured), and associated metadata for all included CPT soundings. We also provide a zipped directory of legacy .txt formatted CPT data for users wishing to reference the original data collected by the USGS.

"Modeling ash dispersal from future eruptions of Taupo supervolcano", by S.J. Barker et al.
This paper uses Ash3d model simulations to calculate the probability of a given tephra-fall thickness from eruptions of the following sizes: 0.1km3, 1 km3, 5 km3, 50 km3, and 500 km3. All volume cases were modeled with umbrella cloud formation, with additional Ash3d simulations for the case of a 0.1 km3 eruption assuming no development of an umbrella cloud. One thousand model simulations were run for each of these cases. The data release contains model outputs from each of the simulations. The results are packaged in separate zip files, one for each case. Zip files are named for the eruption size modeled (e.g. "0.1km3", "1km3", "5km3" etc.). Other source parameters used for these simulations are described in the paper. Each zip file contains similar contents. Below are the contents ...

This U.S. Geological Survey (USGS) metadata release consists of 17 different spatial layers in GeoTIFF format. They are: 1) average water capacity (AWC.zip), 2) percent sand (Sand.zip), 3) percent silt (Silt.zip), 4) percent clay (Clay.zip), 5) soil texture (TEXT_PRMS.zip), 6) land use/land cover (LULC.zip), 7) snow values (Snow.zip), 8) summer rain values (SRain.zip), 9) winter rain values (WRain.zip), 10) leaf presence values (keep.zip), 11) leaf loss values (loss.zip), 12) percent tree canopy (CNPY.zip), 13) percent impervious surface (Imperv.zip), 14) snow depletion curve numbers (Snow.zip), 15) rooting depth (RootDepth.zip), 16) permeability values (Lithology_exp_Konly_Project.zip), and 17) water bodies. All data cover the National Hydrologic Model's (NHM) version 1.1 domain. The NHM is a modeling infrastructure consisting of three main parts: 1) an underlying geospatial fabric of modeling units (hydrologic response units and stream segments) with an associated parameter database, 2) a model input data archive, and 3) a repository of the physical model simulation code bases (Regan and others, 2014). The NHM has been used for a variety of applications since its initial development.The 250-meter (m) raster data sets for soils are derived from the OpenGeoHub's LandGIS data (Hengl, 2018). The 30-meter raster of land use and land cover data are a simplified re-classification version of the North American Land-Change Monitoring System (NALCMS, Latifovic and others, 2012) data following the guidance in Viger and Leavesley (2007). This layer was used to derive rasters representing dominant vegetative cover type, snow, summer and winter rain interception values, leaf cover and loss, and rooting depth. The impervious data was compiled from the Global Man-made Impervious Surface (GMIS) Dataset from Landsat, v1 (NASA, 2010). The tree canopy data was compiled from MOD44B MODIS/Terra Vegetation Continuous Fields Yearly L3 Global 250m SIN Grid V006, (Carroll and others, 2017). The snow depletion data was compiled from data by Liston and others (2009) and further processed using methods by Sexstone and others (2020). All file formats are in GeoTIFF (Geograhpic Tagged Imaged Format).

The Curator sends data and information related to the SPCMSC marine geological sample collection to NCEI to increase their discoverability via the IMLGS. Selected data, documents, and images related to the collection are also archived at NCEI and discoverable via the IMLGS, but the USGS is the authoritative source for all data and information related to USGS geological samples.

This interactive web map shows the locations of permitted water supply (PWS) wells and springs. Expand the legend for an explanation of the symbols. Click on any symbol on the map to display additional information in a pop-up window. Available data include: location coordinates and county name, amount of groundwater withdrawn, water use, well construction information, and national and local aquifer names and USGS stratigraphic codes. A link provided near the bottom of each pop-up window automatically retrieves scanned well construction, modification, and inspection forms, and other electronic documents available for the site in the Kentucky Groundwater Data Repository (https://kgs.uky.edu/kgsweb/DataSearching/Water/WaterQualSearch.asp). Groundwater-quality data are not retrieved automatically because of the excessive number of records typically returned. An additional link is provided to enable searching for groundwater-quality data in the Repository. Some data categories listed above may not be available at all sites. Groundwater withdrawals for water wells are obtained from measurements or estimates of well capacity reported on the water-well construction forms, and are typically determined by the driller after completion and development of a well.

This is a repository of data and analysis methods developed in a comparison of water monitoring data reported on Monitor My Watershed and USGS Water Data. The analysis is summarized in a post on EnviroDIY.org: https://www.envirodiy.org/how-do-envirodiy-monitoring-stations-compare-with-usgs-stations/.

This database has been established as a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, regional contact lists, and general information. The data is made available for use by biologists, interagency groups, and the general public.

The Geological Survey of Canada (Atlantic and Pacific) has collected marine survey field records on marine expeditions for over 50 years. This release makes available the results of an ongoing effort to scan and convert our inventory of analog marine survey field records (seismic, sidescan and sounder) to digital format. These records were scanned at 300 dpi and converted into JPEG2000 format. Typically, each of these files was between 1 to 2 gbyte in size before compression and compressed by a factor of 10:1. Empirical tests with a number of data sets suggest that there is minimal visual distortion of the scanned data at this level of compression. In this KML file, scanned data are available in a reduced-scale thumbnail format and a compressed full-resolution JPEG2000 format.

The gCent Catalog is a repository of earthquake centroids and finite fault source information derived from geodetic observations (Shea & Barnhart, 2022). This database additionally includes the fully processed Interferomatric Synethtic Aperture (InSAR) images (unwrapped interferograms) and line-of-sight (LOS) files that were used to derived the cataloged source parameters. Geodetic observations from InSAR provide valuable measurements of ground displacements caused by earthquakes. These spatially-dense (10s of meters per pixel), near-source observations of ground displacement in turn allow for the well-constrained analysis of the spatial characteristics of earthquakes, including their centroid location, depth, dimensions, orientation, and slip magnitude. These source parameters in turn can inform earthquake response products (i.e., ShakeMap, PAGER) and be used to calibrate or compare seismological information (i.e., ComCat). Additionally, the InSAR images ("interferograms") ca ...

This dataset contains all publicly-available analytical data collected by the U.S. Geological Survey (USGS) at each _location within the Pennsylvania Groundwater Monitoring Network (GWMN) from 2015 to present. Additional analytical data will be appended following the conclusion of each sampling season, and all data is made publicly available in the online National Water Inventory System (NWIS). This dataset serves as a repository for data used by the Pennsylvania Groundwater Monitoring Network map, found here: https://rconnect.chs.usgs.gov/PA_GWMN_map/

This data archive contains datasets developed for the purpose of training and applying random forest models to the Mississippi Embayment Regional Aquifer. The random forest models are designed to predict total stream flow and baseflow as a function of a combination of watershed characteristics and monthly weather data. These datasets are associated with a report (SIR 2022-xxxx) and code contained in a USGS GitLab repository. The GitLab repository (https://code.usgs.gov/map/maprandomforest/) contains much more information about how these data may be used to supply predictions of stream flow and baseflow.
