Data

This dataset is part of a multi-scale assessment and classification for segments of 15 rivers of the Upper Midwest United States that meet various criteria for largeness. All rivers are tributary to the Mississippi River system. The 11,600 kilometers (km) that qualified as large were parsed into 10-kilometer-long segments and classified by major alterations (free-flowing, navigation...

Water quality parameters (water temperature, specific conductance, pH, dissolved oxygen, air temperature, and barometric pressure) were measured in the Verde River over a half mile reach below the confluence with Granite Creek. Measurements were made using a calibrated In-Situ SmarTROLL multiparameter meter on June 13, 2018.

The Louisiana Coastal Protection and Restoration Authority works to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes satellite imagery for...

The Trojan Y Chromosome (TYC) strategy is a promising eradication method for biological control of non-native species. The strategy works by manipulating the sex ratio of a population through the introduction of supermales that guarantee male offspring.

This data release includes 2 child items with tracking data for Yellow-billed loons, a species that breeds in coastal areas of western and northern Alaska and adjacent regions of Russia and Canada. This species winters along the Pacific coasts of North America and Eurasia. Child Item 1: "Argos Satellite Tracking Data for Yellow-billed Loons (Gavia adamsii) - Processed Data" -- Quality

This data release is part of a study examining the use of near-stream groundwater discharge as a tool for Geochemical Exploration. Handcart Gulch is an unmined alpine watershed in Montezuma Mining District in the Colorado Front Range. The streambed is cemented by deep ferricrete deposits. Stream water, groundwater, and ferricrete samples were collected and analyzed to constrain the...

The California volcano locations, threat rank and hazard zones data release contains two shapefiles for download or use as a web map service. The California Volcanic Center Locations shapefile was created to provide a generalized location of volcano hazard sources. The California Volcano Hazard Zones shapefile was created from previously published hazard zone reports. Specific details...

The California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP) submitted 2,994 samples in 2004-2018 to the USGS National Water Quality Laboratory (NWQL) for analysis of pesticide constituents on NWQL schedules 2003, 2032, or 2033, and 840 samples in 2004-2011 for analysis of pesticide constituents on NWQL schedule 2060. Fram and Stork (2019)...

Fibropapillomatosis (FP) is a tumor disease associated with a herpesvirus (Chelonid herpesvirus 5-ChHV5) that affects mainly green turtles globally. Understanding the epidemiology of FP has been hampered by lack of robust serological assays to monitor exposure to ChHV5. This is due in part to inability to efficiently culture the virus in vitro for neutralization assays. Here, we...

Mercury (Hg) concentrations and isotopic compositions were collected in sediments, soils, and suspended particulate matter from Gruber's Grove Bay (GGB) and upstream reference sites to inform future remedial efforts. The highest concentrations and isotopic signatures were observed in soils collected from historic water settling ponds from the Badger Army Ammunition Plant (BAAP)...

The data comprise the initial release of landscape disturbance polygons and lines (sites, pipelines and roads) related to natural gas and oil drilling developed prior to the end of 2013 in the 10-county region along the New York - Pennsylvania border. The study area includes the New York Counties of Allegany, Broome, Chemung, Steuben and Tioga, and the Pennsylvania counties of Bradford...

This dataset includes locations and associated information about mines and mining activity in the contiguous United States. The database was developed by combining publicly available national datasets of mineral mines, uranium mines, and minor and major coal mine activities. This database was developed in 2013, but temporal range of mine data varied dependent on source. Uranium mine...
