Our center has created data portals, geonarratives, and interactive data tools for our data and information products.

Alaska Geochemical Database

The Alaska Geochemical Database Version 4.0 (AGDB4) contains geochemical data compilations in which each geologic material sample has one “best value” determination for each analyzed species. Best values are for mineral exploration and assessment purposes and should not be assumed to be appropriate for other uses.

Colorado Legacy Mine Lands Watershed Delineation and Scoring tool (WaDeS)

This web application, a summarized compilation of central Colorado water chemistry datasets from USGS and EPA, identifies legacy mine sites within the headwaters of central Colorado that could be good candidates for future remediation work based on stream metal concentrations, the number and complexity of mine features, and the potential for high natural background metal concentrations.

Arrastra Gulch, Silverton, CO 3D Data Viewer

Airborne electromagnetic and magnetotelluric geophysical surveys were conducted from 2018 to 2019 in Arrastra Gulch along the southern margins of the San Juan and Silverton calderas. This scene provides 3-D data integration combining electromagnetic data, geologic and historical mine mapping, and high-resolution drone imagery.

Airborne Geophysical Survey Inventory of the US Interactive Application

This is a web application providing interactive search, query, and download of the Airborne Geophysical Survey Inventory of the Conterminous United States, Alaska, Hawaii, and Puerto Rico (Johnson and others, 2019). 

Mississippi Alluvial Plain: Regional Geophysical Survey

The USGS Mississippi Alluvial Plain (MAP) Regional Water Availability Study began airborne geophysical mapping to obtain high-resolution information about the hydrogeologic structure and properties of the aquifer. This geonarrative showcases the geophysical data collected in this effort and provides a three-dimensional view into the Mississippi Alluvial Plain subsurface. 

Mississippi Alluvial Plain: Shellmound, MS Geophysical Survey

A high-resolution airborne and ground-based geophysical survey was conducted near Shellmound, Mississippi as part of the Mississippi Alluvial Plain (MAP) Regional Water Availability Study. This geonarrative showcases the geophysical data used in support of this effort, compiles complementary datasets, and provides additional resources to the user.

USGS Digital Spectral Library

References for material identification in remote sensing images. The library contains spectral reflectance data for of hundreds of materials, including minerals, vegetation, organic and volatile compounds, and man-made materials.
