Water Chemistry Data for Selected Springs, Geysers, and Streams in Yellowstone National Park, Wyoming, Beginning 2009

R. Blaine McCleskey, Randall B Chiu, D. Kirk Nordstrom, Kate J. Campbell, David A. Roth, James W. Ball & Terry I. Plowman
Water analyses are reported for 371 water samples collected from numerous thermal and non-thermal features in Yellowstone National Park (YNP) during 2009?2013. Water samples were collected and analyzed for major and trace constituents from 19 thermal areas of YNP including the Amphitheater Springs area, Nymph Lake area, West Nymph Creek Thermal Area, Norris Geyser Basin, Chocolate Pots, Gibbon Geyser Basin (including Geyser Springs Group, Sylvan Spring area, and Monument Geyser Basin), Secret Valley Hot Springs,...

National Fish Habitat Partnership Projects

These map service layers provide information for projects funded and supported by the 20 regional fish habitat partnerships. Projects funded and supported since 2006 are represented in the service layer and the data are expected to be updated annually. Projects in the database range from on-the-ground restoration, partnership coordination, outreach and education events, and species distribution and habitat assessments.

Airborne Geophysical Surveys over the 2011 Mineral, Virginia Earthquake Area

Anjana K Shah
The 2011 moment magnitude (Mw) 5.8 central Virginia earthquake was felt by millions of people and caused significant damage in the eastern United States. As part of efforts to better understand the faults and geologic features associated with the earthquake, the U.S. Geological Survey commissioned airborne geophysical surveys over the epicentral area. Here we present the data from those surveys and summarize research results based on those datasets.

Mojave Region Water-Level Study, 2012

Nick F. Teague, Christina L. Stamos, Sally F. House & Dennis A. Clark
Regional water-table maps of the Mojave River and Morongo ground-water basins have been published in reports by the U.S. Geological Survey (USGS) every two years since 1992. The water-level reports for the years 1992-2004 were published as USGS Water-Resources Investigations Reports or Scientific Investigations Reports and are available online as separate Portable Document Fomat (pdf) formatted reports, which can be accessed on the "References" page on this website; the water-level contours from most of the...

Dissolved Gas, Environmental Tracer Concentrations, and Lumped Parameter Modeling Results for Groundwater Age Dating in the Glacial Aquifer System, Conterminous United States

John E Solder
This data release documents nine Microsoft Excel tables that contain data for understanding groundwater ages in the Glacial aquifer system. Results for the three sample networks (PAS, principal aquifer study; MSS, modeling support study; FPS, flow path study) are described by three tables each: dissolved gas modeling results, environmental tracer concentrations (tritium, tritiogenic helium-3, sulfur hexafluoride, carbon-14, and radiogenic helium-4), and results for the mean age and age distribution. Tables are labeled by network and...

Carbon Exchange Data - Cypress Swamp Sampling Location (Greater Everglades)

Barclay Shoemaker
This file is an Excel file containing data for the Cypress Swamp sampling location. It includes the following data sheets: -raw_weather - raw data for wind direction, wind gust, incoming solar radiation, soil heat flux, net radiation, air temperature, relative humidity, temperature of air, water and soil, and volumetric water content. -work_weather - mean 30-minute mean calculation for data in raw_weather. This averaging syncs time for weather and eddy covariance data. Wind speed correction for...

U.S. Geological Survey - Gap Analysis Project Species Range Maps CONUS_2001

Alexa McKerrow
GAP species range data are coarse representations of the total areal extent a species occupies, in other words the geographic limits within which a species can be found (Morrison and Hall 2002). These data provide the geographic extent within which the USGS Gap Analysis Project delineates areas of suitable habitat for terrestrial vertebrate species in their species' habitat maps. The range maps are created by attributing a vector file derived from the 12-digit Hydrologic Unit...
