Three different CMIP6-LOCA2 based climate projection data sets are spatially averaged for the contiguous United States using Bureau of Land Management administrative units to provide time series for analysis. The primary data set is the statistically downscaled CMIP6-LOCA2 (Localized Constructed Analogs, v20220519 version, Pierce et al. 2023), which includes temperature and precipitation

Three different CMIP6-LOCA2 based climate projection data sets are spatially averaged for the contiguous United States counties to provide time series for analysis. The primary data set is the statistically downscaled CMIP6-LOCA2 (Localized Constructed Analogs, v20220519 version, Pierce et al. 2023), which includes temperature and precipitation projections from the Climate Model...

Three different CMIP6-LOCA2 based climate projection data sets are spatially averaged over the Watershed Boundary Dataset (WBD) using HU8 and HU10 hydrologic units for the contiguous United States to provide time series for analysis. The primary data set is the statistically downscaled CMIP6-LOCA2 (Localized Constructed Analogs, v20220519 version, Pierce et al. 2023), which includes...

Data include grass carp position and sampling data from 2022 to 2023. We used grass carp that were implanted with acoustic transmitters. The position data was generated in Fathom Position from receivers that composed several VEMCO Positioning Systems (VPS). We also queried the Great Lakes Acoustic Telemetry Observation Network (GLATOS) to obtain non-VPS position detections from receivers...

This dataset includes simulated streamflow and sediment discharge for major tributaries contributing to Clear Lake, California. Historical hourly streamflow and sediment for each tributary location were outputs from an Hydrological Simulation Program - FORTRAN (HSPF) model. The historical data is available at an hourly time step from October 1980 to March 2024. The future time series...

Samples from the Alaska Placer Concentrate Collection (APCC) were retrieved from the USGS National Geochemical Sample Archives and submitted for mineralogical analysis at the Colorado School of Mines. The APPC contains samples from placer mining operations throughout Alaska. The original collection contained approximately 5,000 samples that were collected by U.S. Geological Survey...

This data release contains a bibliography of U.S. Geological Survey publications on carbon and greenhouse gas research. Publications between 2014 and 2024 were identified using search terms such as: carbon, greenhouse gas, methane, nitrous oxide, emission, sequestration, and primary productivity. Publications were primarily sourced from the USGS Publications Warehouse (https://pubs.usgs...

This dataset includes lab data for stable isotopes of fish tissue, invertebrates, and vegetation collected during daylight hours in the Northern Sacramento-San Joaquin Delta and drainage channels of the Yolo By-Pass, California, USA during summer 2022, 2023, and 2024. This data release includes all animal taxa and isotope values.

This model archive (Fan et al. 2025a) provides all data, code, and model outputs used in the corresponding manuscript (Fan et al. 2025b) to test machine learning (ML) methods for downscaling and multi-scale modeling of stream temperature to combine an ML model and/or input data at coarse spatial resolution with an ML model and/or input data at fine spatial resolution to predict stream...

Datasets includes groundwater well locations and 2015 water-level measurements for 31 wells, 20-foot contours, and water-level change for 31 wells measured in 2009 and 2015 of the Cockfield (upper Claiborne) aquifer. Data also includes groundwater well locations and 2015 water-level measurements for 37 wells, 10-foot contours of the northern Wilcox aquifer, 20-foot contours of the...

The products presented here document conditions at the Big Bend restoration site on the Jordan River, West Jordan, Utah in January, 2022. Multiband imagery was collected shortly after the initiation of restoration actions. Images were collected using a 3DR Solo unoccupied aerial system (UAS) at a height approximately 400 feet above the surface of the Jordan River flood plain using a...

Airborne electromagnetic (AEM) and magnetic survey data were collected during November 2017 over a total distance of 1,980 line kilometers in the southwestern San Joaquin Valley of California adjacent to the Elk Hills, North and South Coles Levee, and Buena Vista oil fields. These data were collected in support of groundwater salinity mapping and hydrogeologic framework development as...
