Data compilation of soil respiration, moisture, and temperature measurements from global warming experiments from 1994-2014

This dataset is the largest global dataset to date of soil respiration, moisture, and temperature measurements, totaling >3800 observations representing 27 temperature manipulation studies, spanning nine biomes and nearly two decades of warming experiments. Data for this study were obtained from a combination of unpublished data and published literature values. We find that although warming increa

Tables supporting improved EA-Cr_HTC hydrogen-isotope technique for halogen- and S-bearing organic compounds

Accurate hydrogen isotopic analysis of halogen- and sulfur-bearing organics has not been possible with traditional high-temperature conversion (HTC) because the formation of hydrogen-bearing reaction products other than molecular hydrogen (H2) is responsible for non-quantitative H2-yields and possible hydrogen isotopic fractionation. The elemental analyzerchromium/high temperature conversion react

Irrigation water use in Kansas, 2014

This U.S. Geological Survey (USGS) Data Release represents geospatial and tabular data on irrigation water use in Kansas. The data release was produced in compliance with open data requirements. The dataset consists of 3 separate items with similar attributes aggregated to different geographic extents: 1. Kansas counties; 2. Kansas regional planning areas used in the Kansas Water Plan; and 3.

Airborne Geophysical Surveys over the Eastern Adirondacks, New York State

Airborne geophysical surveys were conducted in the eastern Adirondacks from Dec. 7, 2015 - Dec. 21, 2015, by Goldak Airborne Surveys. The area was flown along a draped surface with a nominal survey height above ground of 200 meters. The flight line spacing was 250 meters for traverse lines and 2500 meters for control lines. Here we present downloadable magnetic and radiometric (gamma spectrometry)

Shakemap earthquake scenario: Building Seismic Safety Council 2014 Event Set (BSSC2014)

This is a catalog of earthquake scenarios, represented as ShakeMaps. A ShakeMap is a USGS product that facilitates communication of earthquake effects by portraying a map of the severity of shaking. Maps of shaking severity are provided in terms of macroseismic intensity, peak ground acceleration, peak ground velocity, and spectral accelerations (at 0.3, 1.0 and 3 sec oscillator periods).

Low-pathogenic avian influenza viruses in wild migratory waterfowl in a region of high poultry production, Delmarva, Maryland

Migratory waterfowl are natural reservoirs for low pathogenic avian influenza viruses (LPAIV) and may contribute to the long-distance dispersal of these diseases as well as spillover into domestic bird populations. Surveillance for AIVs is critical to assessing risks for potential spread of these diseases among wild and domestic bird populations. The Delmarva Peninsula on the east coast of the U.S

Water-Quality Data for Nebraska

Chemical, physical, and biological properties of water, sediment, and tissue samples from Nebraska. Water-quality data are collected as either discrete field measurements or as continuous time-series data from automated recorders that continuously record physical and chemical characteristics including pH, specific conductance, temperature, and dissolved oxygen.

Groundwater Data for Nebraska

Data from wells, springs, test holes, tunnels, drains, and excavations in Nebraska; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

Surface-Water Data for Nebraska

Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in Nebraska. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

Nebraska Continuous Water-Quality Network on WaterQualityWatch

The Nebraska Continuous Water-Quality Network is part of USGS WaterQualityWatch. This web site provides maps that track short-term changes in water quality. Temperature, specific conductance, pH, dissolved oxygen, turbidity, nitrate, discharge, chlorophyll, and surrogate data are available.

Nebraska Real-Time Water Quality on National Real-Time Water Quality

Real-time computed concentrations of water-quality constituents such as suspended sediment, total nitrogen, and total phosphorus are calculated using ordinary least squares regression models. The results of these models, along with direct water-quality measurements, can be viewed here as time-series graphs, or downloaded as tabular data.
