Velocity, Discharge, and Dye Concentrations During a Dye Tracer Study on the Lower Sandusky River, Ohio, July 11-13, 2017 Velocity, Discharge, and Dye Concentrations During a Dye Tracer Study on the Lower Sandusky River, Ohio, July 11-13, 2017
A dye tracer study was completed on the lower Sandusky River between July 11-13, 2017, during a confirmed Grass carp (Ctenopharyngodon idella) spawning event. The data contained in this data release include time series of dye concentration at fixed stations downstream of the injection site and three-dimensional water-velocity data and discharge measurements collected using acoustic...
SUPERSEDED: Data Associated with Algal Toxin Testing of Common Murres (Uria aalge) and Forage Fish in Alaska, 2015–2017 SUPERSEDED: Data Associated with Algal Toxin Testing of Common Murres (Uria aalge) and Forage Fish in Alaska, 2015–2017
This data release has been SUPERSEDED. No data are provided here. Data from HABs sampling data releases have been appended to U.S. Geological Survey data release: https://doi.org/10.5066/P9MLNP9H. This data set is comprised of two tables with results of algal toxin screening for saxitoxin and domoic acid. We used enzyme-linked immunosorbent assay (ELISA) and high-performance liquid...
Concentrations of Pharmaceutical Contaminants and Their Predicted Effects from a Multi-Regional Assessment of Wadeable USA Streams, 2014-2017 Concentrations of Pharmaceutical Contaminants and Their Predicted Effects from a Multi-Regional Assessment of Wadeable USA Streams, 2014-2017
Human-use pharmaceutical compounds were analyzed at the U.S. Geological Survey, National Water Quality Laboratory, Denver, Colorado, in wadeable streams in 4 Regional Stream Quality Assessments: Northeast (NESQA), Southeast (SESQA), Pacific Northwest (PNSQA) and California (CSQA). Multiple (with few exceptions) samplings occurred at each site, during base flow, between 2014 and 2017...
Airborne electromagnetic, magnetic, and radiometric survey of the Mississippi Alluvial Plain, November 2018 - February 2019 Airborne electromagnetic, magnetic, and radiometric survey of the Mississippi Alluvial Plain, November 2018 - February 2019
Airborne electromagnetic (AEM), magnetic, and radiometric data were acquired November 2018 to February 2019 along 16,816 line-kilometers (line-km) over the Mississippi Alluvial Plain (MAP). Data were acquired by CGG Canada Services, Ltd. with three different helicopter-borne sensors: the CGG Canada Services, Ltd. Resolve frequency-domain AEM instrument that is used to map subsurface...
Dissolved gas and tracer concentrations from the Columbia Plateau Aquifer, Vertical Flowpath Study Network Dissolved gas and tracer concentrations from the Columbia Plateau Aquifer, Vertical Flowpath Study Network
This data release documents three Microsoft Excel tables that contain data for understanding environmental tracer concentrations in groundwater of the Columbia Plateau aquifer system. Results of dissolved-gas modeling using environmental tracer concentrations (tritium, tritiogenic helium-3, and radiogenic helium-4), for the sample network (VPFS, vertical flow path study) are described...
