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.

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...
Suspended Sediment Conditions to Hyporheic Dissolved Oxygen and Fine Sediment Deposition in Salmonid Spawning Habitat Below an Irrigation Dam, Park County, Wyoming Suspended Sediment Conditions to Hyporheic Dissolved Oxygen and Fine Sediment Deposition in Salmonid Spawning Habitat Below an Irrigation Dam, Park County, Wyoming
We quantified the effects of dam sediment management operations on downstream salmonid spawning habitat during two fall water-level drawdown periods: an experimental drawdown leading to sediment release or a typical slower drawdown intended to minimize release of sediment. The experimental drawdown increased deposited fine sediment and decreased hyporheic dissolved oxygen levels. However...
Soil texture and hydraulic conductivity at a 1-kilometer resolution for the Contiguous United States based on 30-meter resolution data from the Polaris database.

The U.S. Geological Survey (USGS) Integrated Water Availability Assessments (IWAAs) Program is designed to deliver nationally consistent assessments of water supplies for human and ecological needs, and to identify factors that influence water availability. In support of these studies, a National-Extent Hydrogeologic Framework (NEHF) is under development. The NEHF is a three-dimensional...
