Hydraulic-head datasets for the surficial and Frederica aquifers at Dover Air Force Base, Kent County, Delaware: May 2020, April 2021, and September 2021 Hydraulic-head datasets for the surficial and Frederica aquifers at Dover Air Force Base, Kent County, Delaware: May 2020, April 2021, and September 2021
This data release contains information on hydraulic head in the near-surface aquifers at Dover Air Force Base, a 4,000-acre military installation located in Kent County, Delaware. The hydraulic-head data, collected by the U.S. Geological Survey (USGS) in cooperation with the U.S. Air Force Civil Engineer Center (AFCEC), are based on water-level measurements taken during three synoptic...
Antecedent Flow Volatility, associated risk, and trends at USGS streamgages across the conterminous United States, 1980-2020 Antecedent Flow Volatility, associated risk, and trends at USGS streamgages across the conterminous United States, 1980-2020
This data release supports the analysis published in Cashman and others (2026), Changing hydrologic volatility and associated risk to freshwater biota across the conterminous United States, 1980–2020. See Larger Work citation. This data release contains calculated ecoflow metrics, including Natural Flow Anomalies (NFA) and Antecedent Flow Volatility (AFV), volatility-driven ecological...
Trained monthly natural flow models and calculated natural flow anomalies at reference and biologically-paired USGS streamgages across the conterminous United States Trained monthly natural flow models and calculated natural flow anomalies at reference and biologically-paired USGS streamgages across the conterminous United States
This data release contains the outputs of a national-scale natural flow model and subsequent calculation of natural flow anomalies (NFA) at reference USGS streamgages and USGS streamgages linked to biological sampling sites compiled from USGS National Water Quality Assessment (NAWQA) and EPA Wadeable Streams Assessment (WSA), Environmental Monitoring and Assessment Program (EMAP), and...
Ecological risk response models for antecedent flow volatility effects on freshwater fish and macroinvertebrate communities across the conterminous United States Ecological risk response models for antecedent flow volatility effects on freshwater fish and macroinvertebrate communities across the conterminous United States
This data release contains the outputs, including model objects, of a causal dose-response analysis quantifying how Antecedent Flow Volatility (AFV) affects the probability of poor ecological condition in freshwater fish and macroinvertebrate communities across the conterminous United States (CONUS). Antecedent Flow Volatility (AFV) is defined as the log10-transformed standard deviation...
Smear slide and coarse fraction sediment characteristics of the Samoa Basin collected during cruise 2026-604-FA Smear slide and coarse fraction sediment characteristics of the Samoa Basin collected during cruise 2026-604-FA
USGS cruise 2026-604-FA recovered box cores from the Samoa Basin to characterize the sediments, fauna, and minerals on the abyssal plain. This data-release addresses sediment composition and how it varies across the Samoa Basin. The analyses were carried out primarily to determine which dating methods might be most appropriate to use to date the sediment, such as biostratigraphy...
Geospatial characterization of South Atlantic Bight salt marshes Geospatial characterization of South Atlantic Bight salt marshes
This data release provides conceptual marsh units for salt marshes in the South Atlantic Bight of the southeastern United States. Marsh plains are subdivided into smaller units using a digital elevation model, capturing the spatial variability of physical factors that influence wetland condition. The U.S. Geological Survey is expanding its national assessment of coastal change hazards...

This volume's release consists of 256899 media files captured by autonomous wildlife monitoring devices under the project, Vermont Fish and Wildlife Department Audio Volume 1 (2022). The attached files listed below include several CSV files that provide information about the data release. The file, "media.csv" provides the metadata about the media, such as filename and date/time of...
Apatite (U-Th)/He and zircon (U-Pb) data from Paleogene strata at Marsh Creek on the northeastern Arctic Coastal Plain of Alaska Apatite (U-Th)/He and zircon (U-Pb) data from Paleogene strata at Marsh Creek on the northeastern Arctic Coastal Plain of Alaska
This data release contains apatite (U-Th)/He and zircon U/Pb thermo-/geo-chronologic data from Paleogene strata from the Marsh Creek anticline area of the northeastern Arctic Coastal Plain of Alaska. Apatite (U-Th)/He data are presented for six new samples (1-5 replicates per sample) that span about three kilometers of structural relief. Detrital zircon U/Pb data are presented for five...
