This data set presents the results of conducting Mercury Intrusion Porosimetry on core samples of the mudstone underlying the Naval Air Warfare Center, West Trenton, New Jersey. The core samples were selected from the continuous core collected from boreholes 83BR-89BR.
These data sets present results from the analyses of groundwater samples collected from monitoring wells and monitoring intervals in bedrock wells in the mudstone aquifer underlying the former Naval Air Warfare Center (NAWC), West Trenton, NJ. The water samples were collected between 2008 and 2013 and were analyzed for field parameters, inorganic and organic constituents, and the abundances of selected microbes of importance to the evaluation of biological degradation of organic contaminants in groundwater. The collection and analyses of the groundwater samples coincides with conducting a bioaugmentation experiment in a targeted region of the mudstone aquifer. The purpose of the bioaugmentation was to introduce...

The U.S. Geological Survey (USGS) and the National Park Service (NPS) have collaborated on monitoring the chloride flux in the major rivers of Yellowstone National Park by periodically sampling the rivers and analyzing chloride concentrations in discrete water samples since the 1970's. However, restrictions of winter travel, great distances between sites, and sampling and analytical costs have limited collection to approximately 28 samples per site annually. Electrical conductivity data can be used as a proxy for chloride concentrations in many of the major rivers of Yellowstone National Park. Electrical conductivity is a measure of the ability of water to pass an electrical current, and it is affected by the presence...

The consequence of the 1996 Buffalo Creek wildfire disturbance and a subsequent high-intensity summer convective rain storm (~100 mm h-1) was the deposition of a sediment superslug in the Spring Creek basin (26.8 km2) of the Front Range Mountains in Colorado. Changes in the superslug near the confluence of Spring Creek with the South Platte River were monitored by cross-section surveys at 18 nearly equally-spaced cross sections along a 1500 m study reach for 18 years (1996-2014) to understand the evolution and internal stratigraphy of this type of disturbance in response to different geomorphic processes. These data consist of 18 Excel files (one for each cross section) containing worksheets corresponding to each...

This data set presents the lithologic interpretation of rock cores from boreholes 83BR-89BR collected from the mudstone aquifer underlying the Naval Air Warfare Center (NAWC), West Trenton, NJ. Continuous core from these boreholes was collected and visually interpreted to identify characteristics of the depositional environment of the mudstone. Three types of mudstone were identified: a black-fissile mudstone (BLK-FIS); a gray-laminated mudstone (GRY-LAM); and a gray massive mudstone (GRY-MAS). The BLK-FIS mudstone is associated with a deep-water depositional environment. The GRY-MAS mudstone is associated with a shallow-water depositional environment. The GRY-LAM mudstone is associated with a transitional depositional...
These geospatial data sets were developed as part of a new analysis of all known current and historical rain gages in the Luquillo Mountains, Puerto Rico published in the journal article Murphy, S.F., Stallard, R.F., Scholl, M.A., Gonzalez, G., and Torres-Sanchez, A.J., 2017, Reassessing rainfall in the Luquillo Mountains, Puerto Rico: Local and global ecohydrological implications: PLOS One 12(7): e0180987, p. 1-26, https://doi.org/10.1371/journal.pone.0180987. That article provides a revised map of mean annual precipitation developed using elevation regression functions and residual interpolation, and that map is presented here in a raster file. Most previous forest- and watershed-wide estimates of precipitation...

Extreme climate events– such as hurricanes, droughts, ice storms, extreme precipitation, and wildfires– have the potential to cause large changes in watershed processes, response, and function. A five-year post-wildfire study of stream chemistry in the Colorado Front Range USA, enabled the analysis of the effects these events have water quality, which is published in the journal article Murphy, S.F., McCleskey, R.B., Martin, D.A., Writer, J.H., and Ebel, B.A., in review, Fire, flood, and drought: Extreme climate events alter flowpaths and stream chemistry: JGR-Biogeosciences. That article describes how extreme climate events altered concentration-discharge relations in ways that elucidate hydrologic flow paths and...

The Yellowstone Volcano Observatory (YVO) was established as a collaboration between the U.S. Geological Survey and Yellowstone National Park "To strengthen the long-term monitoring of volcanic and earthquake unrest in the Yellowstone National Park region." Yellowstone National Park is underlain by a voluminous magmatic system overlain by the most active hydrothermal system on Earth. Tracking changes in water and gas chemistry is of great importance because anomalous fluxes might signal one of the earliest warnings of volcanic unrest. Because of the tremendous number, chemical diversity, and large aerial coverage of Yellowstone's thermal features, it remains daunting to monitor individual features that might serve...
This data set presents results from two groundwater tracing experiments conducted in the mudstone aquifer underlying the former Naval Air Warfare Center (NAWC), West Trenton, NJ. In each test, a bromide solution was introduced into a hydraulically isolated section of borehole 36BR (denoted as 36BR-A); the hydraulically isolated section of the borehole isolated specific bedding plane parting fractures intersecting the borehole 36BR. In the first test, initiated in July 2007, water samples were collected from borehole 15BR; borehole 15BR is outfitted with a submersible pump operating continuously as part of the pump-and-treat operation at the NAWC to prevent off-site migration of groundwater contaminants. In the second...

This data release provides measurements of dye concentration collected to support and validate numerical simulations of dispersion on the Kootenai River, downstream of Bonners Ferry, Idaho. On August 13, 2008, at 06:00, 25.4 kilograms of rhodamine WT was diluted using raw river water in a 378.5 liter tank and released as a nearly single slug. The dye was released near River Kilometer (RKM) 239 over a period of 17 minutes. From 06:01 – 06:10 the dye was released at a fairly constant rate, and from 06:10 – 06:18 the dye was released at a slower rate associated with cleaning and rinsing the tank. Measurements of dye concentration were made using water quality sondes with 6130 rhodamine probes. Two sampling strategies...
