Debris-flow monitoring data, Chalk Cliffs, Colorado, USA, 2014 Debris-flow monitoring data, Chalk Cliffs, Colorado, USA, 2014
This data release includes 2014 time-series data from three debris-flow monitoring stations at Chalk Cliffs in Chaffee County, Colorado, USA. The data were collected to help identify the triggering conditions, magnitude, and mobility of debris flows at the site. The three stations are located sequentially along a channel draining the 0.3 km^2 study area. The Upper, Middle, and Lower...
Methylmercury and associated data in macroinvertebrates from tributaries of Honnedaga Lake and from the Middle Branch Black River in New York. Methylmercury and associated data in macroinvertebrates from tributaries of Honnedaga Lake and from the Middle Branch Black River in New York.
Macroinvertebrate samples were collected from streams tributary to Honnedaga Lake and from the Middle Branch of the Black River during 2012-2016 and analyzed for methylmercury concentrations and for stable isotope ratios of nitrogen and carbon. Macroinvertebrates were identified in the field, and the level of taxonomic resolution varied from order to species; most taxa were identified to...
Fish mercury concentration data and ancillary data for streams and rivers across New York States (United States), 1969-2016, including environmental characteristics of selected locations sampled during 2007-16 Fish mercury concentration data and ancillary data for streams and rivers across New York States (United States), 1969-2016, including environmental characteristics of selected locations sampled during 2007-16
Fish mercury (Hg) data were compiled for 392 unique locations on freshwater streams and rivers in New York State for the period 1969-2016. A total of 7620 records were compiled from state, federal, and non-governmental organization databases. The compiled data were for samples of 65 non-anadromous species or species groups in which Hg was analyzed in whole fish or edible flesh, and for...
Geochemical characterization, acid neutralization potential, and phosphate removal capacity of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana, USA Geochemical characterization, acid neutralization potential, and phosphate removal capacity of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana, USA
Steelmaking slag from near Chicago, USA, may be a viable option for treating phosphate-rich or acidic waters. Iron and steel slags from legacy and modern operations in the Chicago-Gary area of Illinois and Indiana, USA, are predominantly composed of Ca, Fe, and Si, with generally lesser amounts of Al, Mg, and Mn. Simulated weathering tests suggest that potentially deleterious elements...
Stable isotope analysis of San Francisco Bay-Delta primary producers (1990-2000) Stable isotope analysis of San Francisco Bay-Delta primary producers (1990-2000)
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 DTSGUI
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...
Investigating fire frequency and vegetative combustion sources using wildland fire tracer molecules archived in the Juneau Icefield of Alaska Investigating fire frequency and vegetative combustion sources using wildland fire tracer molecules archived in the Juneau Icefield of Alaska
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...
Perceived Social Value of the Sonoita Creek Watershed using the Social Values for Ecosystem Services (SolVES) Tool, Arizona, U.S.A. Perceived Social Value of the Sonoita Creek Watershed using the Social Values for Ecosystem Services (SolVES) Tool, Arizona, U.S.A.
Mapping the spatial dynamics of perceived social value across the landscape can help develop a restoration economy that can support ecosystem services in the region. Many different methods have been used to map perceived social value. We used the Social Values for Ecosystem Services (SolVES) GIS tool, version 3.0, which uses social survey responses and various environmental variables to...
Oregon SELDM tools Oregon SELDM tools
A series of tools (spreadsheets, a database and a document) to be used in conjunction with the SELDM simulations used in the publication: Stonewall, A.J., and Granato, G.E., 2019, Assessing potential effects of highway and urban runoff on receiving streams in total maximum daily load watersheds in Oregon using the Stochastic Empirical Loading and Dilution Model: U.S. Geological Survey...

This data release contains data from cores collected in marshes and in sediments under invasive Brazilian waterweed (Egeria densa Planchon) in the Sacramento-San Joaquin Delta of California during the spring of 2018. Data are provided in two text files in comma separated columns. The first Core_Sites_Details.txt contains core site location, collection dates, and naming information. The...
Channel width measurements for selected streamgage sites in Montana Channel width measurements for selected streamgage sites in Montana
The WY-MT WSC conducted a study to develop regression equations for estimating peak-flow frequencies in Montana, using channel-width characteristics. Channel widths were measured in the field and from aerial photographs. This data release includes three child items: a table of field measurements, a table of measurements from aerial photographs, and a summary table of the data (field...
Accelerometer scour monitor data on the South Fork Tolt River, Washington, Water Year 2016 - 2017 Accelerometer scour monitor data on the South Fork Tolt River, Washington, Water Year 2016 - 2017
Accelerometer scour monitors were deployed on the South Fork Tolt River, Washington from Water Year 2016 to 2017 as part of a study on the timing of streambed scour in salmon-spawning habitat. This data release contains data of the three-dimensional orientation recorded at 15-minute intervals for the accelerometer monitors. Each accelerometer scour monitor was comprised of two individual
