Data

This data release contains input data used to test multi-scale modeling approaches for predicting water temperature in streams and rivers. The target application aims to predict stream temperature at relatively fine spatial resolution across a river basin by combining a machine learning (ML) model (optionally, with additional input data) configured at a relatively coarse spatial...

Globally, lakes are losing ice cover, but our understanding of the rates and variability of change are biased towards few lakes with long-term records. Recent works have used remote sensing and predictive modeling to supplement the observational record, but these approaches produce large errors when estimating ice phenology for individual lakes. Our associated manuscript explores machine...

Evaluating Decadal Changes in Groundwater Quality: Groundwater-quality data were collected from 5,000 wells between 1988-2001 (first decadal sampling event) by the National Water-Quality Assessment Project. Samples are collected in groups of 20-30 wells with similar characteristics called networks. About 1,500 of these wells in 67 networks were sampled again approximately 10 years later...

This data release provides field measurements of water depth and aerial and satellite images from the Mulchatna River in Alaska. These data were used to assess the feasibility of mapping the bathymetry of this remote, proglacial river, located in Lake Clark National Park and Preserve, using several depth retrieval algorithms. This approach could facilitate geomorphic and habitat...

This dataset contains satellite-derived information on lake elevations for selected glacial dammed lakes (GDLs) monitored by the National Weather Service Alaska-Pacific River Forecasting Center in Anchorage, Alaska, as well as several Alaska lakes collocated with monitoring gages. The lake elevation data are derived from satellite-observed water surface elevations from the Surface Water...

The recently launched Surface Water and Ocean Topography (SWOT) satellite provides observations of Earth’s rivers and lakes, which sets the stage for innovative application of such data for hydrologic analysis. Here, we apply the LakeFlow algorithm, which leverages mass conservation principles and Bayesian optimization, to estimate lake inflow and outflow discharge at 1,061 North...

Multiple sources of mine drainage including discharge from the abandoned Dinero mine tunnel and two gulches flow into a wetland, known herein as the Dinero wetland along the Lake Fork Creek corridor. The Dinero wetland is approximately xx acres in extent. The Dinero wetland is being considered as a location for passive treatment of the mine drainage flowing through it. As such, study...

This data release provides maps of estimated performance metrics for the remotely sensed evapotranspiration (ET) models within the OpenET ensemble, at the scale of the conterminous U.S. (CONUS). It also provides relative weight maps for each of the ensemble models that can be used to produce performance-weighted ensemble estimates. These maps are provided at a 4 kilometer spatial...

The USGS is conducting a long-term study of a terrestrial crude oil spill that resulted from a ruptured pipeline in 1979. Samples of oil bailed from wells were analyzed for polyaromatic hydrocarbons by a commercial lab. A total of 32 samples were analyzed in three batches. A sample that serves as a surrogate for the original spilled oil was submitted with each batch. For each oil sample

A Lagrangian study was conducted in 2019 that followed two water masses in the Powder River from central Wyoming to southeastern Montana. The study characterized the changes of the in-stream transport of sediment and associated chemical and biological constituents. Depth-integrated water samples (using an isokinetic nozzle) and river bottom sediment samples were collected at six mainstem...

Needle samples from 140 Pinus ponderosa were analyzed for trace elements via inductively coupled plasma mass spectrometry (ICP-MS). Samples were collected from eight locations representing five distinct soil types across the Colorado Plateau near Flagstaff, Arizona and Boulder, Colorado. Data includes a full spectral scan between m/z 5-245 which was condensed to 72 dominant atomic masses

Sediment samples from sites affected by environmental releases of wastewater from oil and gas production were examined to determine sorbed versus mineral structure associations of barium, radium, strontium, and other elements. Archive samples were used from work at Blacktail Creek, North Dakota and Wolf Creek, West Virginia. The Blacktail Creek samples are described in publications and...
