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...

Three different CMIP6-LOCA2 based climate projection data sets are spatially averaged for the contiguous United States using National Park Service 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...

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...

Airborne electromagnetic (AEM) and magnetic survey data were collected during November 2018 over a total distance of 1,480 line kilometers in the Maricopa Flats and surrounding areas of southwestern San Joaquin Valley of California adjacent to the Buena Vista, Midway Sunset, Yowlumne, Los Lobos, Pioneer, Landslide, San Emidio Nose, Rio Viejo, and White Wolf oil fields. These data were...

This dataset includes files associated with a 21-day nutrient diffusing substrate experiment run in Pear Lake of Sequoia National Park, California in summer 2022. The experiment was designed to evaluate the effects of different treatment levels of a macronutrient (nitrogen) and a micronutrient (copper) on periphyton growth and community structure in an alpine lake. While the effects of...

These RNA sequencing (RNA-seq) data were collected to better understand how exposure to environmentally relevant doses of nitrate affects the brain transcriptome in fathead minnows. Fish were exposed to nominal doses of 0, 2, 5, 10, 25, or 100 mg/L nitrate nitrogen (NO3-N), added to flow-through well water as sodium nitrate. Transcriptomic data were collected from three experiments that...

This dataset includes eDNA concentrations of water samples from an experimental release of lake trout (Salvelinus namaycush) slurry used to analyze eDNA transport in the Big Piney River, Missouri. The spectaclecase (Cumberlandia monodonta) was also included as a target species due to the proximity of a known spectaclecase population at the slurry release site. The slurry, a frozen block...

In January 2023, the USGS demonstrated the use of side-scan sonar and down-imaging sonar to locate and quantify fish including invasive carp. A dike pool in the study area was surveyed (254-meter reach) using a Humminbird Helix sonar system. Sonar surveys included concurrent recordings of side-scan and down-imaging sonar. Proprietary sonar data were converted to PNG image files (i.e...

This dataset contains measurements of in situ benthic biofilms from rivers of northwest Alaska during summer and fall 2016-2019. Measurements were made using a Benthotorch (bbe Moldaenke, Kiel, Germany) hand-held fluorometer, which distinguishes taxa (cyanobacteria, green algae, diatoms) and provides estimates of standing biomass.

These data were collected to determine the effect of nitrapyrin, a commercial nitrification inhibitor, on nitrification by a diverse nitrifier-enriched microbial (NEM) community. The NEM community was originally collected from an aquaculture pond in Columbia, Missouri and cultured in HEPES-buffered, minimal mineral salts media, supplemented with a nominal dose of 2 milligrams per liter...
