We present two tabular digital data files representing values related how the presence of hetero- and conspecifics influence nest and chick survival for two listed migratory species breeding on the Missouri River; piping plover (Charadrius melodus) and least tern (Sternula antillarum). We followed 2,507 piping plover nests, 3,251 uniquely banded piping plover chicks, 1,060 least tern...

This groundwater-flow model archive contains heuristic model simulations evaluating the sustainability of groundwater withdrawals from public-water-supply wells on buried glacial aquifers. A total of 40 steady-state simulations and three transient simulations were run. The steady-state simulations were developed to assess the extent and connections between buried sand aquifers by varying...

The USGS examined mercury (Hg) concentrations in fish populations inhabiting impacted and reference streams as part of an investigation into the transport of trace metals in a watershed impacted by legacy mercury mining downstream from the Cinnabar mine site, Valley County, ID. Fish were sampled through an electrofishing survey utilizing a two-pass quantitative depletion approach where...

This data set consists of data collected during 2005-2007, 2010, and 2015 at Neal Smith National Wildlife Refuge in Iowa, USA that were used in the analysis in support of the article titled "Toward improving pollinator habitat: Reconstructing prairies with high forb diversity," which has been submitted to Natural Areas Journal. We compared pollinator habitat, in terms of planted forb...

This data release includes data collected from the Villa Grove helicopter magnetic survey in northern San Luis Valley and Poncha Pass region in south-central Colorado, USA. The survey area extends over the northern part of Great Sand Dunes National Park, Poncha Pass and vicinity, and into the southern end of the Upper Arkansas Valley. It includes the communities of Crestone, Villa Grove...

The 2018 Kilauea eruption and caldera collapse generated intense cycles of seismicity tied to repeated large seismic (Mw ~5) collapse events associated with magma withdrawal from beneath the summit. To gain insight into the underlying dynamics and aid eruption response, we applied waveform-based earthquake detection and double-difference location as the eruption unfolded. Here, we...

A detailed aeromagnetic survey of Mono Basin and Long Valley, California was flown by EON Geosciences Inc. from October 25th to November 11th, 2012. The high-resolution helicopter survey was flown at a flightline spacing of 400 m, a flightline azimuth of 65 degrees, a nominal flightline elevation above ground of 150 m, and consists of about 6,125 line-kilometers. Tie lines were spaced at...

The data in this release originate from a low-altitude, aeromagnetic survey of the Centralia and Chehalis area of southwestern Washington. The survey was conducted between September 22 and October 22, 2015, by Eon Geosciences, Inc, working under contract to the U.S. Geological Survey. The covered region extends from the Cascade Range in the east to Willapa Bay in the west, and includes...

This data release provides access to a low-altitude, aeromagnetic survey of a part of central Washington centered approximately 22 km west-southwest of Ellensburg. The survey includes the cities of Ellensburg, Cle Elum, and Yakima and is referred to as the Cle Elum aeromagnetic survey. The Cle Elum aeromagnetic survey extends from the Columbia Plateau westward to the eastern Cascade...

This data release provides access to a low-altitude, aeromagnetic survey of a part of eastern Washington and northwestern Idaho centered approximately at Spokane, Washington, and referred to as the Spokane aeromagnetic survey. The survey includes the cities of Spokane and Cheney, numerous smaller communities, and Fairchild Air Force Base. Magnetic anomalies reflect Miocene rocks of the...

This data release provides access to a low-altitude, aeromagnetic survey of a part of south-central Washington centered approximately 30 km east of Yakima and referred to as the Hanford aeromagnetic survey. The survey includes the city of Richland, numerous smaller communities, and the Hanford Site (https://www.hanford.gov). The Hanford aeromagnetic survey extends from the Columbia...

This data release provides access to a low-altitude, aeromagnetic survey of a part of south-central Washington and north-central Oregon. The survey extends from the Blue Mountains westward to the Cascade Range and covers the Oregon cities of The Dalles, Hermiston, and Milton Freewater and the Washington cities of Richland, Pasco, Kennewick, and Walla Walla. Data were acquired during the...
