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...

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...

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...

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...

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.

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...

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...

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...

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...

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...

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...

The Louisiana Coastal Protection and Restoration Authority and the Natural Resource Damage Assessment (NRDA) develop restoration plans in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions...
