Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Concentrations of Bioactive Organic Contaminants in Water and Sediment and Rates of Contaminant Biodegradation in Sediment at Congaree National Park, USA 2013-15
Data release including concentrations of bioactive organic contaminants in water and sediment and biodegradation rates of select model contaminants in sediment from Congaree National Park during 2013-15. Chemical analyses for targeted organic analytes include, human-use pharmaceuticals, degradates and metabolites and hormones and organic wastewater indicator compounds. Samples were collected betwe
Analysis of the effect of Hurricane Sandy on New Jersey Atlantic coastal marshes based on landsat thematic mapper and operational land imager data: 2000-2015
This USGS Data Release represents geospatial data sets that were created for the analysis of the effect of Hurricane Sandy on New Jersey Atlantic Coastal Marshes. The following listed image products were generated:
1) Fifteen marsh surface condition index (MSCI) data sets were calculated from yearly summer collections of ETM+ image data from 2000 to 2015. Three classes described the results of
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
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.
