Probabilistic seismic hazard data and maps of American Samoa and Neighboring South Pacific Islands for peak ground acceleration (PGA) and 0.2 and 1.0 second spectral acceleration at...

Seismicity catalogs, GIS shapefiles, gridded seismic hazard curve data, gridded ground motion data, and mapped gridded ground motion values are available for the 2014 National Seismic Hazard Model for the Conterminous U.S. Probabilistic seismic hazard data and maps of the conterminous U.S. for peak ground acceleration (PGA) and 0.2 and 1.0 second spectral acceleration at probability...

Gridded seismic hazard curve data, gridded ground motion data, and mapped gridded ground motion values are available for the 2003 Puerto Rico and U.S. Virgin Islands Seismic Hazard Model. Probabilistic seismic hazard data and maps are available for peak ground acceleration (PGA) and 0.2, 0.3, and 1.0 second spectral acceleration at probability levels of 2 percent in 50 years and 10...

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...
