A series of workshops were held in three Alaskan Native Villages, Aniak, Elim, and St. Mary’s in July 2024. These workshops focused on community observations of and concerns around weather and environmental changes. The workshop participants were community members in each of the respective communities. Participants were provided with an informed consent sheet that explained the risks and...

Actual evapotranspiration (ET) is a key variable for understanding land–atmosphere interactions and for assessing water use in agricultural, ecological, and hydrologic systems. This data release provides global, field‑scale ET data generated from Landsat observations using the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Science Processing Architecture...

Acid mine drainage originating from underground mine workings discharge to surface water within the Lefthand Creek watershed and may adversely affect downstream aquatic ecosystems and habitats. The U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency (EPA), conducted a series of tracer injection tests to study groundwater transport and mixing...

This model archive summary describes the development of an acoustic derived suspended sediment time series computation model. The model archive summary describes the methods and techniques used to develop the model for the Columbia River at Vancouver, WA – USGS site ID 14144700. The time series suspended sediment data will help determine the suspended sediment concentration at the site...

The U.S. Geological Survey, in cooperation with the Minnesota Department of Health, conducted a study to determine the occurrence of unregulated contaminants in source and finished drinking waters throughout Minnesota. Minnesota relies on both groundwater and surface water sources for drinking water, which may be vulnerable to influences such as wastewater discharge and/or agricultural...

Two machine learning (ML) models (random forest [RF] and light gradient boosting machine [LGB]) were developed to estimate water use for mining for all 50 States for each month of 2020. The two ML models were trained using water use data available from 2019 to 2020 for 30 states along with multiple predictor variables on energy resources, mineral production, and mining employment. The...

Potential evapotranspiration (PET) and reference evapotranspiration (ETo) are estimated using the Priestley-Taylor equation and the Penman-Monteith method, respectively (Mecikalski and others, 2018), at an approximately 2-kilometer (approximately 0.019 degrees longitude and 0.018 degrees latitude) spatial grid and daily time-step from January 1, 2025 to December 31, 2025 for the State of...

This dataset provides the locations of putative polar bears that were visually detected within very high-resolution optical satellite imagery on the Beaufort Sea coast of Alaska. Results are provided as geospatial polygons saved in the shapefile format. These data are based on visual interpretation of very high-resolution optical satellite imagery collected at sites on the Beaufort Sea...

The southern portion of the San Francisco Bay (SFB) Estuary, California, is impacted by mercury (Hg) contamination associated with multiple sources, including: a) inputs from the Guadalupe River watershed, which drains the historic New Almaden Mercury Mining district, b) the entrainment of waters from the northern portion of SFB and the Sacramento-San Joaquin Delta, which are also...

Little is known about mercury concentrations at bay margins, and how climate change, including changes in temperature and precipitation, will affect mercury exposure and methylmercury (MeHg) production. In addition, the San Francisco South Bay Salt Ponds Restoration Program (SBSPRP) needs more efficient and effective mercury monitoring approaches at larger spatial scales to understand...

This data release provides per- and polyfluoroalkyl substances (PFAS) data from dragonfly larvae (various species) and surface water collected on National Park Service lands, U.S Fish and Wildlife refuges, and Tribal lands across the continental United States between 2021-2024.
