Volcanic Gas Measurements at Mount Cleveland, 14-15 August 2015

Helicopter-based, upward-looking differential optical absorption spectroscopy (DOAS) measurements of scattered solar ultraviolet radiation and Multi-Component Gas Analyzer System (Multi-GAS) measurements of trace gas concentrations were made while traversing beneath and through the gas plume emitted from Mount Cleveland volcano on 14-15 August, 2016. Radiance spectra and gas compositions were reco

2017 One-Year Seismic Hazard Forecast for the Central and Eastern United States from Induced and Natural Earthquakes

We produced a one-year 2017 seismic hazard forecast for the central and eastern United States from induced and natural earthquakes that replaces the one-year 2016 forecast, and evaluated the 2016 seismic hazard forecast to improve future assessments. The 2016 forecast indicated high seismic hazard (greater than 1% probability of damaging ground shaking in 1 year) in portions of Oklahoma/Kansas, th

Earthquake catalogs for the 2017 Central and Eastern U.S. short-term seismic hazard model

The U. S. Geological Survey (USGS) makes long-term seismic hazard forecasts that are used in building codes. The hazard models usually consider only natural seismicity; non-tectonic (man-made) earthquakes are excluded because they are transitory or too small. In the past decade, however, thousands of earthquakes related to underground fluid injection have occurred in the central and eastern U.S. (

Herpetofaunal inventories of the national parks of South Florida and the Caribbean: Volume I, Everglades National Park

The Comprehensive Everglades Restoration Plan (CERP) requires the use of ecological indicators to measure the success of restoration efforts. The Everglades amphibian community is ideal because amphibians are present in all habitats and under all hydrologic regimes. During Everglades restoration, hydrologic patterns will change and the response of ecological indicators will determine success. Fo

Data for herpetofaunal inventories of the national parks of South Florida and the Caribbean: Volume II, Virgin Islands National Park

The Comprehensive Everglades Restoration Plan (CERP) requires the use of ecological indicators to measure the success of restoration efforts. The Everglades amphibian community is ideal because amphibians are present in all habitats and under all hydrologic regimes. During Everglades restoration, hydrologic patterns will change and the response of ecological indicators will determine success. Fo

Geochemical and geochronologic data from the Hall Creek caldera, Toiyabe Range, Nevada

The magmatic, tectonic, and topographic evolution of what is now the northern Great Basin remains controversial, notably the temporal and spatial relation between magmatism and extensional faulting. This controversy is exemplified in the northern Toiyabe Range of central Nevada, where previous geologic mapping suggested the presence of a caldera that sourced the late Eocene (34.0 mega-annum [Ma])

Data for herpetofaunal inventories of the national parks of South Florida and the Caribbean: Volume IV, Biscayne National Park

The Comprehensive Everglades Restoration Plan (CERP) requires the use of ecological indicators to measure the success of restoration efforts. The Everglades amphibian community is ideal because amphibians are present in all habitats and under all hydrologic regimes. During Everglades restoration, hydrologic patterns will change and the response of ecological indicators will determine success. Fo

Data for herpetofaunal inventories of the national parks of South Florida and the Caribbean: Volume III, Big Cypress National Preserve

The Comprehensive Everglades Restoration Plan (CERP) requires the use of ecological indicators to measure the success of restoration efforts. The Everglades amphibian community is ideal because amphibians are present in all habitats and under all hydrologic regimes. During Everglades restoration, hydrologic patterns will change and the response of ecological indicators will determine success. Fo

Snake dermatitis data

Snake fungal disease (SFD) is an emerging disease of wild snakes in eastern North America caused by the fungus Ophidiomyces ophiodiicola. The data presented here describe: 1) the types of fungi recovered in culture from the skin of snakes with and without fungal skin infections, 2) the presence or absence of skin lesions in populations of snakes surveyed at several sites in Wisconsin and Minnesota

WaterQualityWatch for Nebraska

WaterQualityWatch is a USGS web site that provides access to real time water-quality data collected in surface waters throughout the United States as part of the USGS mission to describe water resources. Measurements include streamflow (through WaterWatch) water temperature, specific conductance, pH, dissolved oxygen, turbidity, and nitrate. 

Microsomal EROD data of fish liver sample assay from species collected in the Salt and Gila Rivers, Arizona

This dataset includes microsomal EROD data from a liver sample assay. The samples are from several fish species that live in the Salt and Gila rivers, Arizona at sites that are being assessed for PBDE contamination. The data was created in September and October 2016.

Ascii grids of predicted pH in depth zones used by domestic and public drinking water supply depths, Central Valley, California

The ascii grids associated with this data release are predicted distributions of continuous pH at the drinking water depth zones in the groundwater of Central Valley, California. The two prediction grids produced in this work represent predicted pH at the domestic supply and public supply drinking water depths, respectively and are bound by the alluvial boundary that defines the Central Valley.
