Samoan swallowtail butterfly reproductive life history and parasitism, 2013-2014

This data release includes metadata and tabular data documenting the reproductive demography of the Samoan swallowtail butterfly (Papilio godeffroyi), including rates of parasitism by two species of Ooencyrtus wasp. Data was collected at approximately monthly surveys of marked host trees (Micromelum minutum) at eight forest stands, mostly in or adjacent to the National Park of American Samoa (NPSA

Estimated low-flow statistics at ungaged stream locations in New Jersey, water year 2022

Estimates of various low-flow statistics were computed at 56 ungaged stream locations throughout New Jersey during the 2022 water year using methods in the published reports, 1) Streamflow characteristics and trends in New Jersey, water years 1897-2003 (Watson and others, 2005) and 2) Implementation of MOVE.1, censored MOVE.1, and piecewise MOVE.1 low-flow regressions with applications at partial-

Water column and sediment incubations to measure dissolved organic matter dynamics in the Fox rivermouth (Lake Michigan; 2016-2017)

These data are associated with experiments performed in 2016 and 2017 in the Fox rivermouth (Green Bay, WI; Lake Michigan). Between the De Pere Dam and the Lake Michigan coastline, we performed experiments to measure water column transformation of dissolved organic matter (DOM) and sediment flux of DOM. These experiments consisted of incubations of surface water or intact sediment cores and repeat

Greenhouse gas fluxes and dissolved greenhouse gas concentrations from wetland soil microcosms treated with herbicides

This data release presents data from a laboratory microcosm study examining the potential effects of herbicide application on the production and flux of greenhouse gases from wetland soils. Wetland soils were placed into glass mason jars and covered with water. Microcosms were treated with varying concentrations (none, low, medium, high) and combinations of the herbicides glyphosate and 2,4-D. Fol

Gravity data in the Wet Mountains area, southcentral Colorado, 2023

The U.S. Geological Survey collected ground gravity data as part of a helicopter reconnaissance campaign of the Democrat Creek alkaline complex and Deer Peak quadrangle in the Wet Mountains, Colorado. A total of 60 measurements were collected using a LaCoste and Romberg gravity meter. High accuracy geographic coordinates and elevations were collected using a survey grade Leica GS16 differential GP

Screening geochemistry, gas chromatography, and solid bitumen reflectance data in the Bakken petroleum system, Williston Basin, USA

Thirty-two organic-rich samples from the lower and upper shale members of the Devonian–Mississippian Bakken Formation were collected from eight cores across the Williston Basin, USA, at depths (~7,575–11,330 ft) representing immature through post peak oil/early condensate thermal maturity conditions. Reflectance results were correlated to programmed temperature pyrolysis parameters [hydrogen index
