High latitude, boreal watersheds are nitrogen-limited ecosystems that export large amounts of organic carbon. Key controls on carbon cycling in these environments are the biogeochemical processes affecting the nitrogen cycle. This data release presents results of a 3-year field study from 2008-2011 to document the relation between seasonal and transport-associated changes in carbon and...

The software program, QRev, written in Python, computes the discharge from moving-boat ADCP measurements using data collected with any of the Teledyne RD Instrument (TRDI) or SonTek bottom tracking ADCPs. The computation of discharge is independent of the manufacturer of the ADCP because QRev applies consistent algorithms independent of the data source. In addition, QRev automates...

This dataset is a compilation of multiple studies over different periods and in many environments as described below. These data were collected to measure temporal fluctuations in plant isotopic composition associated with seasonal cycles of growth and environmental variability. In 1990, 1992, and 1998-2000, a total of 868 samples were collected and analyzed to determine carbon and...

DTSGUI is a public-domain software tool to import, manage, parse/cull, georeference, analyze and visualize fiber-optic distributed temperature sensor (FO-DTS) data. Visualization can efficiently be accomplished in the form of heat maps of temperature (as color) versus distance and time, and in map view plots of georeferenced data on land-surface orthoimagery. The code is written in...

The past decade includes some of the most extensive boreal forest fires in the historical record. Environmental drivers include warming temperatures, changing precipitation patterns, desiccation of thick organic soil layers, and increased ignition frequency from lightning. Wildland fires produce smoke aerosols that can travel thousands of kilometers, before blanketing the surfaces on...

The need to assess the effects of variability in climate, biota, geology, and human activities on water availability and flow can be assessed with computer models that simulate the hydrologic cycle at a watershed scale. The Precipitation-Runoff Modeling System (PRMS) is a deterministic, distributed-parameter; physical process-based modeling system developed to evaluate the response of...

This dataset contains modeled hourly streamflow in cubic meters per second at each of about eighteen thousand selected operational and water-quality stream gage locations. It was assembled from publicly available retrospective V2.0 National Water Model outputs. The streamflow variable was extracted from model output files and the data were reshaped to optimize read performance. The...

The data represent a shallow mercury chronology using sediment core from a playa lake system situated in a high-altitude setting in northwest Argentina. Archive samples were used from sediment core (LP07-1A) that was collected from a location (lat -22.362100, lon -66.003600) in the center of the playa-lake Laguna de Pozuelos in the dry season of 2007, when the water level was 2 to 3 cm...

Near-surface geophysical data from within the Bonita Peak Mining District in Silverton, Colorado, USA are presented. The data include fiber optic distributed temperature sensing (FO-DTS) and frequency domain electromagnetic induction (FDEM) data collected in and around roughly 1 km reaches of Cement Creek and California Gulch. Additional data, including ground penetrating radar (GPR) and...

This data release contains files for three scenarios of an analytic element (GFLOW) groundwater flow model with particle-tracking that were developed in cooperation with the Lac du Flambeau Band of Lake Superior Chippewa and Indian Health Service to map the probablistic plume extent for a proposed waste-water infiltration lagoon, along with maps to delineate the area contributing...

Measuring the thermal output of Yellowstone’s large magmatic system is not straightforward, as there are thousands of thermal features spread across 3470 square miles. One way to capture and integrate the thermal discharge from this broad area is to monitor river chemistry, because thermal water discharge eventually enters a nearby river, which acts as a collection and delivery system...

The West Fork of Dall Creek is located ~100km southwest of Coldfoot, AK along the Dalton Highway, south of the Brooks Range. The West Fork of Dall Creek is composed of unburned black spruce forest with a burn scar from the 2004 Dall City Fire. Multi-season, multi-method geophysical data were collected both within the burned and unburned areas. Geophysical techniques used include Nuculear...
