Passive seismic depth to bedrock data collected along headwater stream corridors in the Neversink River watershed, NY, USA The Neversink River watershed (above the Neversink Reservoir) has been a focus of U.S. Geological Survey (USGS) research regarding stream geochemistry, acidification, and ecology dynamics for decades. In 2019, the Water Mission Area Next Generation Water Observing Systems Program augmented the existing stream gage network there, including instrumentation to specifically characterize various aspects of groundwater discharge to streams. An important control on the spatiotemporal dynamics of groundwater discharge can be stream valley corridor depth to bedrock, otherwise conceptualized as the thickness of unconsolidated sediments sediments over the contiguous bedrock interface. In June 2019, and November 2020, passive...

Electrode arrays made up of four stainless steel rods (insulated with the exception of exposed 0.5 cm tips) were installed vertically at depths of interest and apparent electrical resistivity data (the inverse of bulk EC) were collected using a Wenner configuration with an AGI SuperSting R8 meter. The Bulk EC data are described and listed within the files below. Controlled, downward flow experiments were conducted in Dual-domain porosity apparatus (DDPA). Downward flow rates ranged from 1.2 to 1.4 m/d in DDPA1 and at 1 m/d, 3 m/d,... Tags: Groundwater, Inland Waters, Massachusetts, Sandwich, Snake Pond, All tags...

Matheson Wetlands Preserve near Moab, Utah The electrical conductivity of the earth is used to help infer lithological and pore fluid properties. Various geophysical methods can provide estimates of the distribution of below ground electrical conductivity, with each method having certain limitations. This data release presents raw and processed results from land-based and water-based frequency domain electromagnetic induction imaging (EMI) data collected from March 31 to April 2, 2015. Data were primarily collected by walking throughout the wetland and riparian zones with the GEM-2 instrument (Geophex, Ltd.) at approximately 1 m off the ground in horizontal coplanar (ski flat) mode. A survey along a section of the Colorado River in a kayak was also collected... Tags: Groundwater, InlandWaters, Moab, Scott M. Matheson Wetlands Preserve, Surface Water, All tags...

Matheson Wetlands Preserve Near Moab, Utah Quantitative evaluation of groundwater/surface water exchange dynamics is universally challenging in large river systems, because existing physical methodology often does not yield spatially-distributed data and is difficult to utilize in deeper water. Here we apply combined frequency domain electromagnetic induction (EMI) and direct contact vertical electrical sounding (VES) measurements to identify shallow, fresh groundwater discharge to the Colorado River through a 4 km2 wetland that borders the town of Moab, Utah, USA. EMI data were collected by a mobile tool that was hand carried or floated on the back of a kayak, providing extensive spatial coverage for the upper approximate 5 m of river channel/sediments....

Lightweight thermal sensors provide another sensor option for generation of sub meter resolution aerial thermal infrared orthophotos that can be used to infer hydrogeological processes. UAS-based sensors allow for the rapid and safe survey of groundwater discharge areas, often present in inaccessible, boggy, and/or dangerous terrain. Visible light and thermal infrared image data were collected March 2018 and March 2019, respectively, at Tidmarsh Farms, a former commercial cranberry bog located in coastal Massachusetts, USA...

Zones in groundwater flow-through lakes where lake water recharges the aquifer can strongly control aquifer water quality. Less-mobile porosity has previously been characterized in aquifers using flow path scale (10's of m+) tracer injections which are analyzed using numerical models. Methodology was recently developed to couple geoelectric measurements (bulk electrical conductivity, EC), which are directly sensitive to less-mobile ionic tracer exchange processes, with pumped fluid EC tracer data over time. If the fluid EC concentration history... Tags: Groundwater, Groundwater and Streamflow Information Program, InlandWaters, Massachusetts, Sandwich, All tags...

Changes in fluid electrical conductivity (EC) during controlled downward ionic tracer injections into interface sediments can be assumed to represent mobile porosity dynamics, which are therefore distinguished from less-mobile porosity dynamics that is measured using bulk EC geoelectrical methods. Fluid EC samples were drawn at flow rates similar to tracer injection rates to prevent inducing preferential flow. The data were collected using a stainless steel tube with slits cut into the bottom (USGS MINIPOINT style) connected...

Matheson Wetlands Preserve near Moab, Utah Vertical electrical soundings (VES) are used to develop depth-resolved models of aquifer resistivity by making electrical potential measurements at increasingly larger electrode spacing, with the array centered around a common point. Variations in modeled electrical resistivity with depth can be used to infer groundwater salinity and preferential fresh groundwater flow zones. Each of the 4 VES measurement integrates approximately 11 individual electrical soundings with 4 electrodes driven into the soil in a linear Wenner array with electrode spacings ranging from 1 to 40 m. Data were collected manually with a SuperSting electrical resistivity meter (AGI - Advanced Geosciences, Inc) and recorded by hand in a field...
