Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Geologic Map of Northeasternmost Tennessee, and Adjacent Parts of Virginia and North Carolina Geologic Map of Northeasternmost Tennessee, and Adjacent Parts of Virginia and North Carolina
The geology of an area of 660 square miles mostly in the northeastern corner of Tennessee and small adjacent areas in Virginia and North Carolina is the subject of this report. The region lies principally in the Unaka province, with extensions northwestward into the Appalachian Valley and southwestward into the Blue Ridge province. The report combines results of surveys made between 1941...
Gravity data in the Wet Mountains area, southcentral Colorado, 2021 to 2022 Gravity data in the Wet Mountains area, southcentral Colorado, 2021 to 2022
The U.S. Geological Survey (USGS) collected gravity data in the Wet Mountains, CO from September 2021 to July 2022 to compliment newly collected airborne magnetic data for surface and subsurface geologic mapping. A total of 261 measurements were collected across two Ediacaran-Ordovician alkaline complexes (Gem Park and McClure Mountain) and gabbroic outcrops suspected Ediacaran...
Magnetic susceptibility measurements in the Wet Mountains, Colorado, 2021 to 2022 Magnetic susceptibility measurements in the Wet Mountains, Colorado, 2021 to 2022
The U.S. Geological Survey (USGS) collected rock magnetic susceptibility measurements to understand the causative sources of airborne magnetic survey anomalies in the Wet Mountains, Colorado. A total of 808 measurements were collected over 50 locations from August 2021 to June 2022 on rocks ranging from Paleoproterozoic to Oligocene age. These measurements aid the interpretation of newly...
Abundance, density, habitat placement and behaviors of Eumunida picta in the western Atlantic off the southeastern U.S. coastline from 2000-2009 Abundance, density, habitat placement and behaviors of Eumunida picta in the western Atlantic off the southeastern U.S. coastline from 2000-2009
Data on the abundance, density, habitat placement and behaviors of Eumunida picta observed from analyzed videos recorded during submersible dives from 2000-2009 in the western Atlantic off the southern U.S. coastline.
Functional diversity metrics of floodplain forests from Michigan's Lower Peninsula Functional diversity metrics of floodplain forests from Michigan's Lower Peninsula
Floodplain forest species are presumed to interact strongly with the environment, as evidenced by pronounced spatial variation in flood-driven abiotic constraints and forest composition. These data describe functional diversity and environmental characteristics for 156 forest assemblages sampled on floodplain landforms within transects from the lower peninsula of Michigan. The functional...
Cross-section geometry and sediment-size distribution data from the Upper Colorado River, April 6-8, 2022 Cross-section geometry and sediment-size distribution data from the Upper Colorado River, April 6-8, 2022
The U.S. Geological Survey collected geomorphic monitoring data in cooperation with the Upper Colorado River Wild and Scenic Stakeholder Group. This data release contains cross-section geometry and sediment-size distribution data collected from five sites on the Upper Colorado River, Colorado during April 6-8, 2022. The five sites selected for monitoring were located at the Pumphouse...
