The data set consists of 3 spreadsheets: counts, efforts, and location that detail the 10-year removal effort of invasive Veiled Chameleons (Chamaeleo calyptratus) on the island of Maui. Recorded are the number of lizards removed from each site, the level of search effort at each site, and the centroid location of each sampled site.

Generate plots and statistics for single earthquake catalogs and for catalog to catalog comparisons.

In 2013 the U.S. Geological Survey (USGS) drilled and logged a continuous core located on the northeast flank of the Alcova anticline in the southeastern part of the Wind River Basin, Wyoming to evaluate the source rock potential of the Lower and lowermost Upper Cretaceous marine shales (fig. 1). The well, named the Alcova Reservoir AR-1-13, was spud in the lower part of the Frontier...

Footprints were generated for each lidar (light detection and ranging) dataset published by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) since 2001. The purpose of this data release is to provide an easily accessible index of the coverage of available lidar data. Relating these footprints to field activities and publications allows users to...

This database contains aquatic benthic macroinvertebrate abundance data derived from samples collected from 33 75-meter stream site locations within the Delaware Water Gap National Recreation area in September of 2006. The database contains two separate table files (i.e., entities) in csv format: 1) Macroinvertebrate site abundance data and 2) site location data. For macroinvertebrate...

Selected archived sample splits collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program, were reanalyzed by the U.S. Geological Survey (USGS) as part of a NURE-HSSR Reanalysis project (Smith and others, 2018). A small amount (approximately 0.25 grams [g]) of sieved less than 75-micron sample material was...

This Data release includes time series data collected at Operable Unit 1, Naval Base Kitsap, Keyport, WA and bounding surface water bodies over a 3 week period from 07/12/2018 to 08/08/2018. Groundwater altitudes in nineteen monitoring wells and surface water altitude and water quality parameters in five surface water bodies were monitored. Time series data were collected covered a...

Beaver Lake was constructed in 1966 on the White River in the northwest corner of Arkansas for flood control, hydroelectric power, public water supply, and recreation. The surface area of Beaver Lake is about 27,900 acres and approximately 449 miles of shoreline are at the conservation pool level (1,120 feet above the North American Vertical Datum of 1988). Sedimentation in reservoirs...

This tabular data set contains estimates of total phosphorus concentration and mass, as well as measurements of water discharge and volume at a diked wetland pool (Pool 2B) that was reconnected to a Lake Erie tributary (Crane Creek) via a water control structure in March 2011. Sampling occurred during 2013 and 2014. In addition, this data set contains evaluations of movement of total...

This U.S. Geological Survey (USGS) Data Release provides data to estimate water use associated with continuous oil and gas development in the Williston Basin during 1980-2017. Data included: Data records from the national hydraulic fracturing chemical registry, FracFocus, including the state, county, latitude and longitude of each well, and the year and volume of water used for hydraulic

Western U.S. rangelands have been quantified as six fractional cover (0-100%) components over the Landsat archive (1985-2018) at 30-m resolution, termed the "Back-in-Time" (BIT) dataset. Robust validation through space and time is needed to quantify product accuracy. We leverage field data observed concurrently with HRS imagery over multiple years and locations in the Western U.S. to...

Seismicity catalogs, gridded seismic hazard curve data, gridded ground motion data, and mapped gridded ground motion values are available for the 2008 National Seismic Hazard Model for the Conterminous U.S. (1) Seismicity catalogs are available for the western U.S. (in Mw) and central and eastern U.S. (in mb). (2) Gridded (0.05 degree by 0.05 degree) ground motion values and hazard maps...
