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.

Geochemical analysis of authigenic carbonates, water column, and pore fluids measurements collected on the FK190612 research expedition in the north Pacific Ocean along the Cascadia margin in June 2019
These are data related to the collection of samples on the FK190612 research expedition in the north Pacific Ocean along the Cascadia margin in June 2019.
Von Damm Vent Field geochemical and mineralogical data
This data release contains geochemical data, X-ray diffractograms (XRD), inorganic carbon isotope values, and Raman spectra from rocks collected in 2020 at Von Damm vent field on the Mid Cayman Rise.
Digital elevation models for the Everglades Depth Estimation Network with elevation uncertainty treatment
The Everglades Depth Estimation Network (EDEN) produces daily depth estimates for the Greater Everglades. This data release includes geospatial data to produce depth estimates for the EDEN from updated digital elevation models. The data release includes three main types of data: 1) 10-m digital elevation models (DEMs) with elevation uncertainty treatment; 2) 50-m DEMs with elevation uncertainty tr
Numerical model files for simulating future climate scenarios, Yucaipa Valley watershed, California
Managing water resources in semiarid watersheds is challenging because of limited water supply and uncertain impacts of future climate conditions on groundwater resources. This paper examines the impact of future climate changes on the urban Yucaipa Valley watershed in southern California using an integrated hydrological model referred to herein as the Yucaipa model. Coupled Groundwater and Surfac
Data release for determination of antimycin–a in liquid formulation by high performance liquid chromatography–mass spectrometry
Pesticide formulations containing the active ingredient Antimycin-A (ANT-A) have been used by fisheries and aquaculture managers for several decades to remove nuisance fish species. Analytical methods for measuring ANT-A during pesticide treatments have been reported using High Performance Liquid Chromatography (HPLC) paired with multiple detection methods (e.g., electrochemical, ultraviolet, fluo
Simulations of the groundwater-flow system in the Cache and Grand Prairie Critical Groundwater Areas, northeastern Arkansas
The Mississippi Alluvial Plain (MAP) is one of the most important agricultural regions in the United States and underlies about 32,000 square miles of Missouri, Kentucky, Tennessee, Mississippi, Louisiana, and Arkansas. The MAP region supports a multibillion-dollar agricultural industry. The MAP is part of the Mississippi Embayment with several water-bearing units that make up the Mississippi Emba
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 bedrock and grou
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 sediment vibrac
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
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 gravity and
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 drainage area
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 temperatures
