Data

The U.S. Geological Survey (USGS) collected porewater samples from nine suction lysimeters in 2018, 2019, and 2021 for analysis of organic and inorganic constituents from the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, MN. In August of 1979, approximately 1,700,000 L (liters), or 10,700 barrels, of crude oil spilled onto a glacial outwash aquifer...

This product contains code to analyze a dataset that was collected to compare a LAMP assay and a qPCR assay for Grass Carp in a pond study. This repository contains the RMarkdown and R files used to analyze the data. It was created to allow for reproducible results. The code assumes the user is experience with R, especially the Tidyverse, and Stan.

The validity of Myotis occultus as a species unique from M. lucifugus has been a source of debate. Most recently, many authorities treat M. occultus as a distinct species, at least in part because a previous study showed that M. occultus and M. l. carissima (the subspecies that occurs in closest proximity to M. occultus) form separate monophyletic clades based on sequences of two...

Water primrose (Ludwigia hexapetala) is an invasive aquatic plant that has rapidly increased in coverage throughout the Sacramento-San Joaquin Delta. Water primrose has invaded wetlands and may contribute towards mortality of tules (Schoenoplectus spp.) and cattails (Typha spp.). Little research has been completed on the mechanisms responsible for marsh loss, but previous studies have...

The U.S. Geological Survey (USGS) used an analytic-element method (AEM) modeling approach to quantitatively understand groundwater dynamics at the Captain Jack Superfund Site, located in Boulder County, Colorado. The Captain Jack Superfund Site hosts extensive interconnected underground mine workings.The U.S. Environmental Protection Agency has instituted a remedial strategy of...

This data release contains estimates of annual nitrogen and phosphorus loads, as well as loads of other constituents, from sites in the Illinois Environmental Protection Agency (Illinois EPA) Ambient Water Quality Monitoring Network. The loads were estimated using Weighted Regressions on Time, Discharge, and Season with Kalman filtering (WRTDS-K) and existing discrete water-quality data...

This report includes the first substantive body of in situ density, bearing strength, shear strength, and moisture content data measured by Project personnel. Emphasis in this fiscal year's measurements was on low-density materials since available data suggest that the upper meter or so of the lunar surface consists of low-density material.

Chemical and microbiological results, quality assurance and quality control, site location, and method information for surface water, bed sediment, and wastewater effluent collected from 34 stream locations across Iowa (United States). Environmental samples were analyzed for a suite of 29 antibiotics, plated on selective media for 15 types of bacteria growth, and DNA was extracted from...

This data set includes information on collections of surface water and fecal samples from wild gulls (Larus spp.) at two locations on the Kenai Peninsula, Alaska, USA. Samples were screened for Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) and tested for resistance to multiple antibiotics.

Details of field exercises to assess the readiness of astronauts to perform geologic investigations on the lunar surface. They include landscape description, geologic mapping, mobile traverse descriptions, impact crater description, depression description, and detailed mapping.

A record of aircraft and pavement ice control products applied at Mitchell International Airport in Milwaukee, WI during water years 2015 - 2021, with an accompanying chemical analysis of the phosphorus content and chemical oxygen demand of those products.

Code release for a statistical framework that provides a solution to overcome institutionally siloed monitoring activities in order to inform species conservation across large landscapes. Stan code and documentation to provide access and adaptation for other wildlife disease applications.
