The U.S. Geological Survey obtained measurements of channel geometry, flow velocity, and river discharge from five rivers in Alaska September 18–20, 2016, to support research on remote sensing of river discharge. The streamflow data were acquired from the Knik, Matanuska, Chena, and Salcha Rivers and Montana Creek using TeleDyne RD Instruments Acoustic Doppler Current Profilers (ADCPs), including the RioPro, StreamPro, and RiverRay models. The original *.mmt and *.pd0 format files are provided in this data release. This data release supports the following article: Legleiter, C.J., Kinzel, P.J., and Nelson, J.M., 2017, Remote measurement of river discharge using thermal particle image velocimetry (PIV) and various...

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...

Wastes from the world’s largest manufacturer of DDT were released into the Los Angeles County municipal sewer system from 1947 to 1971. Following primary treatment, the effluent was discharged from a submarine outfall system whereupon a portion of the DDT and associated degradation products were deposited in sediments of the Palos Verdes Shelf (PVS). Parent DDT is present only in trace amounts in the sediments today, the vast majority having been transformed to DDE shortly following deposition. Previously believed to be inert, DDE is slowly being converted to DDMU and DDMU to DDNU via microbially-mediated reductive dechlorination (RDC). Kinetic and compositional data suggest that this process began sometime in the...

The Ankeny, Iowa wastewater treatment facility (WWTF) was decommissioned in November 2013 providing a unique opportunity to characterize the impacts of WWTF discharge on water quality at the surface-water/groundwater interface in a shallow, unconfined alluvial aquifer. The Ankeny WWTF discharged treated effluent for nearly forty years into Fourmile Creek, located in Ankeny, Iowa. Dataset includes site information (Table 1), analytical methods (Table 2), piezometer water level elevations (Table 3), trace and major element concentrations collected from 2011 to 2013 before the WWTF shutdown (Table 4), and trace and major element concentration collected from 2013 to 2014 after the WWTF shutdown (Table 5).

The dataset consists of 2 separate items: 1. Smith Creek floodplain soils dataset (tabular data) 2. Smith Creek bank soils dataset (tabular data) These data support the following publication: Gillespie, J.L., Noe, G.B., Hupp, C.R., Gellis, A.C., and Schenk, E.R.,...

A long-term study of the geomorphic history of the lower Rio Puerco arroyo in north-central New Mexico included the collection of high-precision (Real-time kinematic) GPS survey data (2002, 2007, 2010, and 2014), registration and rectification of historical aerial photographs (1935, 1950s, 1970s, and 1996), an aerial LiDAR survey (2005) with collection of digital imagery, and acquisition of post-flood (2006) satellite imagery. The Rio Puerco is a single-thread, meandering stream inset within an arroyo located in semiarid north-central New Mexico. The study reach extent is from the confluence with the Rio San Jose 67 km downvalley to the Rio Puerco streamgage near Bernardo, NM. Arroyo and channel geomorphic features...

Stream restoration goals include reducing erosion and increasing hyporheic exchange to promote biogeochemical processing and improve water quality. Suspended fine particles (<100 µm) exchange with transient storage areas near and within streambeds and banks. Fine particle deposition and retention directly impact carbon and nutrient cycling by supporting benthic and hyporheic metabolism, but accumulation of fine-particle deposits can impair metabolism by burying benthic biofilms and reducing streambed permeability. Little is known on how fine particle dynamics respond to stream restoration. We analyzed the transport and retention of water and fine particles at both the reach- and local-scale in a restored urban stream,...

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...

NOTE: This data release has been deprecated. In support of the USGS LandCarbon project, field observations of stream and lake carbon gas fluxes and other water-quality data were collected from surface waters in the conterminous US. The sampling was designed to cover a variety of geographic, climatic, and environmental settings to better understand the ranges and distributions of carbon gas fluxes from surface waters. Field observations of carbon gas concentration and flux were paired with laboratory measurements of stream chemical characteristics. Locations were derived from field GPS values or from listed coordinates of USGS streamgages located at the sampling site. Discharge data was either measured in the field...

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...

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...
