Data

These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post-2026) Environmental Impact Statement (EIS). These data were compiled to predict economic impacts to angling in Glen Canyon and whitewater rafting in Grand Canyon. The objective of our study was to estimate recreation impacts, or changes in consumer surplus, under...

This dataset collection supports adaptive management planning for black ash wetlands threatened by emerald ash borer (EAB) across Minnesota and provides the underlying data used in an ArcGIS StoryMap outlining strategies for black ash wetland management. There is one csv file containing wildlife habitat model data and four shapefiles included in this collection. The black ash complexes...

This data release provides both the input datasets and modeled output estiamtes generated from eight lake metabolism models, which quantify gross primary production (GPP), ecosystem respiration (ER), and net ecosystem production (NEP). Seven of the lakes were monitored by the National Ecological Observatory Network (NEON), and one by the U.S. Geological Survey (USGS Site No. 01670144)...

This dataset includes field and laboratory analyses of water samples collected from lakes, ponds, rivers, and streams in northwest Alaska within Cape Krusenstern National Monument, Noatak National Preserve, Kobuk Valley National Park, Gates of the Arctic National Park and Preserve, and Bering Land Bridge National Preserve. At sites across the five national park units, in situ water...

These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post 2026) Environmental Impact Statement (EIS). These data were used to illustrate how six operational strategies (one baseline and 5 alternatives) for Glen Canyon Dam could affect sand exposure for aeolian landscape and cultural site resources within Grand Canyon...

This data release compiles multi-year temperature datasets from the Santa Ana River, including continuous temperature records collected by USGS, San Bernardino Valley Municipal Water District, and Riverside-Corona Resource Conservation District to support analyses of spatial and temporal thermal conditions.

The U.S. Geological Survey (USGS) maintains shoreline positions for the United States coasts from various historical sources, such as aerial photographs or topographic surveys, and contemporary sources, such as lidar-point clouds and digital elevation models. Shorelines are compiled in a GIS and analyzed in the USGS Digital Shoreline Analysis System (DSAS) software to calculate rates of...

This data release contains optical measurements for surface water samples collected during synoptic raft trips during three different sampling events. Data collection was performed by the University of Colorado at Boulder, Colorado (CO), and the U.S. Geological Survey (USGS) in Lakewood, CO. The raft was steered in the center of the river thalweg, generally between Kremmling, Colorado...

This data set was collected as part of structured decision-making workshops designed to build Bayesian Decision Networks of habitat management actions in wetlands of the Atlantic Coast Joint Venture region. The models were created as part of an adaptive management framework to reduce uncertainty about management actions. We used formal elicitation process for expert judgment where...

A campaign microgravity network was established at Yellowstone Caldera, Wyoming, in 2017 as a subset of stations that were initially measured in 1977. The network has been measured subsequently on a quasi-annual basis to assess changes in gravity over time that may be related to subsurface magmatic or hydrothermal processes. This data release includes microgravity data collected by the U...

Data from a laboratory study undertaken at the U.S. Geological Survey to investigate solid/water partitioning of per- and polyfluoroalkyl substances (PFAS) in New Hampshire soils and biosolids are presented here. Soils and biosolids used for the experiments were collected using PFAS-free sampling equipment, air dried, gently homogenized, and sieved (soils only). Soil samples were...

Anthropogenic background concentrations of per- and polyfluoroalkyl substances (PFAS) in shallow soils (zero to six inches in depth) across Maine, New Hampshire, and Vermont are compiled in this data release, together with a summary table of soil PFAS method detection limits. New Hampshire samples were collected in 2021 (Santangelo and others, 2022), Vermont samples were collected in...
