Data

Towed transient electromagnetic (tTEM) data were acquired during August 2021 in Historic Jamestowne, which is part of Colonial National Historic Park of Virginia. Members of the U.S. Geological Survey, Hydrogeophysics Branch, and the Virginia-West Virginia Water Science Center collected approxximately 15.7 line kilometers of tTEM data along the the Tour Road in James City County...

The U.S. Geological Survey is monitoring concentrations of metals and other trace elements in streambed sediment and aquatic invertebrates in post-wildfire watersheds in five western states including California, Oregon, Montana, Colorado and New Mexico. This data release makes available major and minor trace element concentrations in bed sediment and aquatic invertebrates collected from...

This data release includes 3 child items with tracking data for caribou, a terrestrial mammal that ranges between the Alaska and Canada. Child Item 1: "GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Denali Herd, Alaska, 2010-2018" Child Item 2: "GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Fortymile Herd, Alaska, 1998-1999" Child Item 3: "GPS...

This data release includes 2 child items with tracking data for Marbled murrelets tagged in Washington state and Alaska, 2008 and 2013. Child Item 1: "Argos Satellite Tracking Data for Marbled Murrelets (Brachyramphus marmoratus - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Marbled Murrelets...

This dataset contains gene expression data for brook trout (Salvelinus fontinalis) collected from the Loyalsock Creek watershed in Pennsylvania. Gene expression was quantified for three genes of interest: elongation factor 1-alpha (EF1), SfontSerpinh1 (a heat shock protein gene), and SfontColdRNA (a gene associated with cold response). The dataset was generated to support investigations...

Invasive carp (silver carp, bighead carp, grass carp, and black carp) are a highly impactful species with high fecundities, and they are currently expanding their ranges throughout the Central United States. These four species are known to avoid the conventional gear used to capture native fish species, and traditional removal methods are highly inefficient at capturing fish when at low...

During August 2023, transient electromagnetic (TEM) surveys were carried out at select locations in Lake County near Leadville, Colorado upgradient from the Dinero tunnel bulkhead. TEM data were collected using an ABEM WalkTEM2 advanced instrument running acquisition software version 1.3.7.4 and using a single-turn transmitter loop (Tx) and a center-loop receiver (Rx). Tx loop dimensions...

This data release contains Mann-Kendall trend results (p-values and Theil-Sen slope values) of water use data in either 8-digit Hydrologic Unit Code (HUC08) or Van Metre hydrologic regions across the conterminous United States (CONUS) for the period 2000-2020. Trends are computed for 7 timesteps: annual, winter (Dec, Jan, Feb), spring (Mar, Apr, May), summer (Jun, Jul, Aug), fall (Sep...

Note: this data release has been superseded by version 3.0, available here: https://doi.org/10.5066/P1BCA8QV. The National Water Quality Network (NWQN) for Rivers and Streams includes 105 surface-water river and stream sites monitored by the U.S. Geological Survey (USGS) National Water Quality Program. This data release provides streamflow, nutrient, and sediment data collected and...

The data release includes a fish sampling dataset and a dataset of estimates of stream temperature and discharge. These datasets were created to assess how Yellowstone cutthroat trout (Oncorhynchus virginalis bouvieri; formally Oncorhynchus clarkii bouvieri) responded to interannual changes in stream temperature and discharge and the occurrence of non-native brown trout (Salmo trutta)...

This data release contains two MODFLOW 6 simulations. Each simulation contains one groundwater flow (GWF) model and one groundwater energy (heat) (GWE) transport model. The GWF and GWE models are constructed to match the setup of the Barends analytical solution for two-dimensional heat transport. This allows the accuracy of the new GWE model to be verified so existing and prospective...

Autonomous recording units are increasingly being used to monitor wildlife on large geographic and temporal scales, paired with machine learning (ML) to automate detection of wildlife. However, false positive detections from ML classifiers can result in erroneous ecological models that can lead to misguided management and conservation actions. We used a two-stage general approach to...
