We used spatial data from previously mapped preferential groundwater discharges throughout the Farmington River watershed in Connecticut and Massachusetts (https://doi.org/10.5066/P915E8JY) to guide water sample collection at known locations of groundwater discharging to surface water. In 2017 and 2019 - 2021, samples were collected during general river baseflow conditions (July – November, <30.9 cms mean daily discharge (USGS gage 01189995, statistics 2010-2022) when the riverbank discharge points were exposed. We collected a suite of dissolved constituents and stable isotopes of water directly in the shallow saturated sediments of active points of discharge, and coincident stream chemical samples were also collected...

Areas of groundwater discharge are hydrologically and ecologically important, and yet are difficult to predict at the river network scale. Thermal infrared imagery can be used to identify areas of groundwater discharge based on an observed temperature anomaly (colder during the late summer or warmer during the late winter). The thermal images, direct temperature measurements (11 cm depth) and discharge zone (seep) location information in this data release were collected as part of a study to evaluate and improve predicted spatial patterns of groundwater discharge. The data were collected during the late summer / early fall of 2017 along selected river reaches in the Farmington River watershed (Connecticut and Massachusetts)....

Using the horizontal-to-vertical spectral-ratio (HVSR) method, we infer regolith thickness (i.e., depth to bedrock) throughout the Farmington River Watershed, CT, USA. Between Nov. 2019 and Nov. 2020, MOHO Tromino Model TEP-3C (MOHO, S.R.L.) three-component seismometers collected passive seismic recordings along the Farmington River and the upstream West Branch of Salmon Brook. From these recordings, we derived resonance frequencies using the GRILLA software (MOHO, S.R.L.), and then inferred potential regolith thicknesses based on likely shear wave velocities, Vs, intrinsic to the underlying sediment. Three potential shear wave velocities (Vs = 300m/s, 337m/s, 362 m/s) were considered for Farmington River watershed...

This dataset contains field measurements of temperature in shallow vertical profiles beneath a lake-bottom in the vicinity of a permeable reactive barrier (PRB) at Ashumet Pond, Falmouth, MA. From August 21, 2015 – September 3, 2015 vertical temperature profilers designed to quantify groundwater upwelling dynamics were installed at seven locations. Hollow stainless steel pipes (2.5 cm OD) were slotted horizontally to allow installation of iButton thermal data loggers (Maxim Integrated DS1922L, 0.0625 oC precision) protected with waterproof silicone caulking. The temperature profilers were gently tapped into the cobbly bed by first driving guide-hole of slightly smaller diameter. After installation, the thermal loggers...

This child item contains fiber-optic distributed temperature sensing (FO-DTS) data collected along the streambed interface of two streams named Cement Creek and California Gulch Creek located near Silverton Colorado. The FO-DTS method utilizes the temperature-dependent backscatter of light pulses emitted along armored fiber-optic cables to evaluate temperature at discrete linear sampling locations. For these deployments a Salixa XT-DTS control unit (Salixa Ltd, Hertfordshire, UK) was used, and measurements were made over several day increments at 0.508 m linear resolution along the streambed interface. Specific locations for collected data are located within the data files, and additional details are contained in...

This dataset contains field measurements of direct groundwater seepage by using half-barrel style seepage meters permanently installed in a lake-bottom permeable reactive barrier (PRB) at Ashumet Pond, Falmouth, MA. The meters are a modified version of a standard half-barrel seepage meter. Each meter consists of a 208-L polyethylene, corrosion-inhibiting drum cut to a length of 0.8 m and fitted with a removable 0.56-m-diameter lid. A 1.3-cm-diameter hole was drilled into each lid to allow outflow or inflow to be measured. During installation, the top rim of each barrel was positioned to be at the expected grade after backfilling. Between 2004 and 2015, seepage rates at each meter were measured annually, with the...

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...

In summer in Massachusetts, USA, preferential groundwater discharge zones are often colder than adjacent streambed areas that do not have substantial discharge. Therefore, discharge zones can efficiently be identified and mapped over space using heat as a tracer. This data release contains fiber-optic distributed temperature sensing (FO-DTS) data collected along the streambed interface of the main channel and tributaries of the upper Quashnet River, within approximately 1 km of Johns Pond, from June 14 to June 20, 2020. For these deployments a Salixa XT-DTS control unit (Salixa Ltd, Hertfordshire, UK) was used, and measurements were made over several day increments at 0.508 m linear resolution. Specific locations...

The U.S. Geological Survey, along with scientists from Rutgers University, collected water chemistry, electromagnetic, redox-potential, dissolved oxygen, water flow rate, and water temperature data along stream and river corridors in multiple sub-watersheds of the East River Science Focus Area (SFA) near Crested Butte, CO. The concept of ‘river corridor’ science recognizes that the quality of flowing surface waters is intrinsically linked to their contributing catchments through hydrologic connectivity, including lower terrestrial hillslopes, floodplains, and riparian zones. Bidirectional river-floodplain exchange in particular can be critical to basin water storage and nutrient transformation dynamics, yet floodplain...

Locations of focused (or ‘preferential’) groundwater discharge to surface water are often hydrologically and ecologically important, yet our ability to predict the spatial distribution and water quality of preferential riverbank discharges is limited at the scale of river networks. To advance the understanding of the physical controls on riverbank groundwater discharge processes, discharge zones can be mapped efficiently using handheld and drone-based thermal infrared cameras. Groundwater discharge locations can be identified based on ‘anomalous’ thermal signatures, such as relatively cold riverbank zones in summer and warm riverbank zones in winter. Thermal infrared imaging can be combined with concurrent direct...

The Upper Delaware River is a unique example of an aquatic system where summer river temperature is actively managed for ecological purposes. River temperature at the mainstem Delaware River at Lordville, NY gage (USGS 01427207) is targeted to remain below 25°C, with warm events potentially mitigated via directed upstream reservoir releases, a process guided by predictive tools. These directed releases currently occur at the Cannonsville Dam on the West Branch, though the temperature criteria at the Lordville gage is also influenced by releases from the Pepacton Dam on the east branch. To increase the spatial resolution of summer river temperature data available for understanding river temperature processes and...

This data release documents streambed sediment thickness in the Neversink watershed (NY) as determined by field observations and HVSR passive seismic measurements, and were collected as an extension of a previous data set collected in the same watershed (see Associated Items). These measurements were made between May 17, 2021 and May 21, 2021 using MOHO Tromino three-component seismometers (MOHO, S.R.L.). Seismic observations were converted to sediment thickness (depth to bedrock, meters) using the horizontal-to-vertical spectral ratio (HVSR) method. Resonance frequencies were determined from time domain data using GRILLA (MOHO, S.R.L.) software and converted to inferred depth to bedrock for a range of possible...
