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.

Airborne electromagnetic and magnetic survey of Illinois River Basin, 2023 Airborne electromagnetic and magnetic survey of Illinois River Basin, 2023
Airborne electromagnetic (AEM) and magnetic survey data were collected during January and February 2023 over a distance of 3,799.3 line kilometers covering the Illinois River Basin and surrounding regions in Illinois and Indiana. Data were collected as part of the USGS Illinois River Basin Next Generation Water Observing Systems (NGWOS) project to improve understanding of depth to...
Sedimentologic Data From Vibracores Collected in 2023 From St. Andrew Bay, Florida Sedimentologic Data From Vibracores Collected in 2023 From St. Andrew Bay, Florida
In April 2023, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) collected 11 sediment vibracores within East Bay, St. Andrew Bay, Florida (FL). Sediment vibracore and lithology data in this data release provide assessments on the composition and age of sediments below the seafloor. This data release serves as an archive of...
Principal facts of regional gravity data in the central Upper Peninsula, Michigan, 2022-2023 Principal facts of regional gravity data in the central Upper Peninsula, Michigan, 2022-2023
Gravity data were collected in 2022 and 2023 to assist in mapping surface and subsurface geology in the central Upper Peninsula of Michigan. This data release provides principal facts for 666 new gravity stations that were acquired to supplement existing public gravity data coverage.
Density and magnetic susceptibility measurements on Precambrian rocks in the central Upper Peninsula, Michigan, 2021-2022 Density and magnetic susceptibility measurements on Precambrian rocks in the central Upper Peninsula, Michigan, 2021-2022
The U.S. Geological Survey (USGS) collected rock physical property measurements to help understand causative sources of gravity and magnetic survey anomalies in the central Upper Peninsula of Michigan. A total of 1,460 measurements of magnetic susceptibility and density from 61 outcrops and 37 boreholes have been conducted on Precambrian rocks. The measurements aid in interpretation of...
Autonomous Underwater Vehicle Water-Quality Measurements in the Cape Fear River, multiple locations, North Carolina, 2022 Autonomous Underwater Vehicle Water-Quality Measurements in the Cape Fear River, multiple locations, North Carolina, 2022
This U.S. Geological Survey (USGS) data release presents water-quality and bathymetric data measured with an Autonomous Underwater Vehicle (AUV) during spatial surveys in the Cape Fear River near Lock and Dam 1 near Riegelwood, NC and at the confluence of the Haw and Deep Rivers near Moncure, NC in 2022. The Cape Fear River Basin is contained entirely within North Carolina and has a...
High resolution natural color and thermal imagery collected by uncrewed aircraft system (UAS) for mapping vegetation change and natural spring identification at Tavasci Marsh in the Tuzigoot National Monument, AZ during 2023-2024 High resolution natural color and thermal imagery collected by uncrewed aircraft system (UAS) for mapping vegetation change and natural spring identification at Tavasci Marsh in the Tuzigoot National Monument, AZ during 2023-2024
The U.S. Geological Survey collected low-altitude airborne natural color imagery, thermal imagery, and 10-band multispectral imagery (2023 only) via a hexacopter uncrewed aircraft system (UAS) in 2023 and 2024 for mapping effects of fire at Tavasci Marsh in the Tuzigoot National Monument in Arizona. Visual imagery was collected to derive high-resolution natural color, thermal (surface...
