These tabular data were compiled to monitor vegetation and biocrust cover two previously grazed grassland located in the Needles District of Canyonlands National Park. Objectives of this study are to document potential changes in biological soil crust (biocrust) and vegetation cover and species composition over time and with ongoing U.S. National Park Service (NPS) management. These data...

These data are for a geochronologic study of Cretaceous Elkhorn Mountains Volcanics and several discrete satellite plutons adjacent to the Cretaceous Boulder batholith of western Montana. Zircon from the two volcanic units of the Elkhorn Mountains Volcanics and four samples of satellite plutons of the Boulder batholith were dated by sensitive high resolution ion microprobe (SHRIMP). When...

This dataset includes raster images of trends in normalized difference vegetation index (NDVI) derived from Sentinel-2 imagery for riparian vegetation within the Los Planes watershed of Baja California Sur, Mexico. A model was first trained to identify riparian vegetation using cloud-masked Sentinel-2 imagery from 2016-2024 and stream delineations derived from a 10m Japanese Aerospace...

Aquatic reflectance data from Sentinel-2 satellite imagery is paired with discrete chlorophyll measurements across Oregon, Ohio, and Florida in the United States. The dataset contains a csv data file (CyAN_S2_Matched_WQ_S2.csv), a csv data dictionary file (CyAN_S2_Matched_WQ_S2_data_dictionary.csv) that describes each of the columns in the data file, and a zip file of python scripts...

Temporal changes in gravity, also called microgravity in volcano geodesy and exploration geophysics applications, provide a means of measuring mass change beneath the surface—for example, due to the accumulation or withdrawal of water, magma, or other fluids. Relative spring-based gravimeters, however, require calibration to establish consistency between instruments, and to assess...

The Great Basin of the Western United States hosts dozens of terminal lake systems that provide critical, abundant, and diverse ecosystems that support migratory bird species, local wildlife, and nearby communities. Water quality varies across terminal lakes in the region depending on basin geology, anthropogenic water use, climate, hydrology, and water quantity. Seasonal and long-term...

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 riparian plant communities along the Colorado River between Glen Canyon Dam and Lake...

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 the impact of different proposed alternatives for Glen Canyon Dam operations on sand resources, including sand mass balance, sandbar volume, and frequency/duration of controlled...

This dataset encompasses a series of files related to a comprehensive ecotoxicology research project conducted in high elevation lakes of the Tokopah Basin in Sequoia National Park. The dataset includes detailed sampling data that reflects the copper concentrations at multiple levels of the food web. This dataset also includes morphometric data for collected fish, biomarkers of fish...

This dataset represents passively detected locations of acoustic telemetry tagged Black Carp in the Mississippi and Missouri rivers near their confluence. These river segments consisted of both open river and impounded habitat present during observed hydrologic conditions from 2021-2023. Receiver arrays were set in known use areas (determined by active relocations of tagged fish) and set...

This data release contains summary metrics describing stream stage, stream water temperature, and short-term climate conditions (daily precipitation and air temperature) for 30 streams spanning gradients of forest and agricultural land uses and the implementation of agricultural best management practices in a mixed agricultural region in Pennsylvania and Maryland, USA. This setting is...
