Data

Sites in Texas that have annual groundwater data for 20 years or more.

Real-time groundwater levels from more than 40 sites across Texas.

Real-time streamflow conditions from more than 600 sites across Texas.

Compiled 1086 datasets of plant seed production spanning 1900-2013 and from around the world were binned into 2-decade periods for which CV (coefficient of variation) of seed set was calculated. Skewness, dip test, mean, and kurtosis were calculated for the same periods.

This data release contains breeding-bird densities in native mixed-grass prairie collected from 2003 to 2012 at and adjacent to wind farms in North and South Dakota, USA, for one year prior to turbine construction and several years post-construction. One dataset contains breeding-bird densities per 100 ha by distance from turbines for categories of 0-100 m, 100-200 m, 200-300 m, and...

High radium (Ra) concentrations in potable portions of the Cambrian-Ordovician (C-O) aquifer system were investigated using water-quality data and environmental tracers ( 3H, 3Hetrit, SF6 , 14C and 4Herad) of groundwater age from 80 public-supply wells (PSWs). Groundwater ages were estimated by calibration of tracers to lumped parameter models and ranged from modern (1 Myr) in the most...

This data release includes time-series data from two monitoring stations in a small drainage basin burned in the 2014 Silverado Fire, Orange County, California. One station (upper station) is located in the headwaters of the study area (33 4539.10N, 117 3517.48W, WGS84). The other station (lower station) is located at the outlet of the study area (33 4504.61N, 117 3512.54W). The data...

This data release describes micrometeorological and soil-moisture data collected from January 1, 2012 through December 31, 2016 at the Amargosa Desert Research Site adjacent to a low-level radioactive waste and hazardous chemical waste facility near Beatty, Nevada. Micrometeorological data include precipitation, solar radiation, net radiation, air temperature, relative humidity...

The files on this page contain the data used for the research described in in the paper, "Challenges in complementing data from ground-based sensors with satellite-derived products to measure ecological changes in relation to climate lessons from temperate wetland-upland landscapes" (Gallant, A.L., Sadinski, W., Brown, J.F., Senay, G.B., Roth, M.F. 2018. Sensors). Supplementary Datafile...

The Weldona 7.5' quadrangle is located on the semiarid plains of northeastern Colorado, along the South Platte River corridor where the river has incised into Upper Cretaceous Pierre Shale. The Pierre Shale is largely covered by surficial deposits that formed from alluvial, eolian, and hillslope processes operating in concert with environmental changes from the Pleistocene to the present...

This dataset contains the observed and simulated streamflow used to produce the results of the journal article entitled Bias correction of Retrospective Simulation of Daily Streamflow at Ungauged Locations Using Independently Estimated Flow-Duration Curves . Observed streamflow, retrieved from the U.S. Geological Surveys National Water Information System (https://waterdata.usgs.gov/nwis)...

Prey fish were collected at 17 Forsters tern breeding colonies during colony visits from 2005-2015. Prey fish were identified to the lowest taxonomic category. We present relative abundances by colony and year for each of the 10 major species groups. Unidentified fish species or rarely observed species were combined into an Other category. We calculated an arithmetic mean, standard...
