The temperature and surface geophysical data contained in this release have primarily been collected to support groundwater/surface water methods development, and to characterize the hydrogeological controls on native brook trout habitat. All data have been collected since 2010 along the Quashnet River corridor located on Cape Cod, MA, USA. Cape Cod is a peninsula in southeastern coastal Massachusetts, USA, composed primarily of highly permeable unconsolidated glacial moraine and outwash deposits. The largest of the Cape Cod sole-source aquifers occupies a western (landward) section of the peninsula, and is incised by several linear valleys that drain groundwater south to the Atlantic Ocean via baseflow-dominated...

Common offset ground penetrating radar (GPR) data were collected to image near surface streambed structure. These data are to be used in conjunction with fiber-optic distributed temperature sensing (FO-DTS) and electromagnetic imaging (EMI) data. The combined dataset represents point in time mapping of preferential groundwater discharge points (FO-DTS) and the bed structure that controls where these points are located (GPR, EMI).
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...
Chemical and geophysical data collected along Oh-be-joyful Creek, Gunnison National Forest, Colorado
As part of their Watershed Function Scientific Focus Area (SFA), Berkeley Lab and its collaborating institutions (e.g., USGS) have established a "Community Watershed" in the headwaters of the East River near Crested Butte, Colorado (USA), designed to quantify processes impacting the ability of mountainous systems to retain and release water, nutrients, carbon, and metals. The ongoing research spans a range of scales from hillslope to catchment to basin, with surface water and groundwater linking multiple geomorphic compartments. A major goal of this SFA research is to generate a transferable understanding of mountain hillslope to river dissolved nutrient, carbon, and metals transport, integrating extensive and novel...
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...

Hand-carried frequency domain electromagnetic imaging (EMI) data were collected along the Sanuit River to indicate changes in streambed water quality and/or near surface sediments. These data are to be used in conjunction with fiber-optic distributed temperature sensing (FO-DTS) and ground penetrating radar (GPR) data. The combined dataset represents point in time mapping of preferential groundwater discharge points (FO-DTS), and the bed structure that controls where these points are located (GPR, EMI).
This page provides access to infrared, multispectral, visual image data, and derivative products collected along a beaver-impacted section of the East River from August 12-17, 2017 and July 28-August 2, 2018. This page may be updated in the future with additional data and analysis related to drone-based imaging.
Fiber-optic distributed temperature sensing (FO-DTS) cables were deployed along the sediment/water interface to map high spatial resolution temperature variations along the streambed. These variations are used to detect zones of groundwater discharge. Data are to be used in conjunction with electromagnetic imaging (EMI) and ground penetrating radar (GPR) data. The combined dataset represents point in time mapping of preferential groundwater discharge points (FO-DTS), and the bed structure that controls where these points are located (GPR, EMI).
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...

This data set summarizes measurements of water flux (specific discharge, or Darcy flux, q) made with seepage meters at 27 sites in five ponds on western Cape Cod during August–September 2015. The seepage meters consisted of the cut-off ends of 55-gallon steel drums, as described in Lee (1977) and Rosenberry and LaBaugh (2008). The seepage meters were 0.56 meter in diameter and covered a surface area on the lake bottom of about 0.25 square meter. The data table provides locational information for each seepage-measurement site, including easting and northing, in meters relative to the Massachusetts State Plane coordinate system (North American Datum of 1983); and the approximate lake-water depth, in meters. The data...
This data set summarizes seepage rates calculated from the lake-bottom temperature data as described in child item "Calculations of lake-bottom seepage rates from vertical temperature profiles at four groundwater flow-through glacial kettle lakes, western Cape Cod, Massachusetts, 2016–18." The data table provides locational information for each site, including easting and northing, in meters relative to the Massachusetts State Plane coordinate system (North American Datum of 1983); approximate distance from shoreline, in meters; and approximate lake-water depth, in meters. The data table also provides the arithmetic average and standard deviation of temperature-derived seepage rate for each time series (in .csv...
Hydrologic data were collected in the nearshore lake-bottom sediments of five lakes on western Cape Cod, Massachusetts: Ashumet (Falmouth), Long (Centerville), Santuit (Mashpee), Shubael (Barnstable), and Snake (Sandwich) Ponds. Water budgets of flow-through glacial kettle lakes are commonly dominated by groundwater flow into and surface-water seepage out of the lake, and inputs and losses from precipitation and evaporation are typically smaller. This data release presents water flux data collected from sites at the five lakes where lake water is seeping downward across the groundwater/surface-water interface into the groundwater system. Detailed characterization of water flux across the lake-bottom interface is...
Heat is used as a tracer for a variety of physical hydrogeological process. For ongoing studies related to groundwater/surface water exchange, temperatures of streambed sediment along the bank, in drainage ditches, and in the river were measured using handheld thermal infrared (FLIR Systems, Inc) cameras and thermocouple (Digi-Sense, Inc) probes. Thermal surveys of the Quashnet river were completed from August 14 to August 25, 2017. Zones of spatially-preferential groundwater discharge were identified as cold anomalies in summer, reflecting the influence from groundwater temperatures of approximately 11 degrees Celsius.
Heat is used as a tracer for a variety of physical hydrogeological process. Several types of instruments are used to measure the temperature of surface water and saturated sediments. In the Quashnet River we have been using methods that include: infrared, fiber-optic distributed temperature sensing, and individual logging thermistors. The latter type of data (thermistor) are described and presented here.
Surface geophysical tools remotely sense hydrogeological properties that can control subsurface flow and water quality. There are numerous geophysical tools, for the Quashnet River work we have principally used ground penetrating radar (GPR) and electromagnetic imaging (EMI). The instruments are either hand carried or floated down the stream channel and other cross-sections of the river corridor. Data from various field deployments of GPR and EMI are described and presented here.
The Massachusetts Division of Fisheries and Wildlife has been studying brook trout populations in Cape Cod groundwater-fed river systems for decades. Recently, a notable reduction in trout population in the Santuit River sparked the concern of several groups, including the Wampanoag Tribe. Brook trout population dynamics may be tied to water quality and temperature changes, which are both impacted by spatially preferential groundwater discharge to the river. The streambed interface temperature and near-surface geophysical data compiled in this data release were collected in summer 2018 as part of a larger effort to characterize the spatial distribution of groundwater discharge zones, and exchanges with surface water,...
The data set includes temperature data from the base of the water column along the sediment interface of Ellerbe Creek, Durham, North Carolina, USA, in support of a study regarding groundwater/surface water exchange. The data were collected from 07/18/2017 to 07/26/2017 using a fiber-optic distributed temperature sensing system that has 1.01 m spatial resolution along the linear fiber-optic cable. During data analysis, the original 15 min measurments were averaged (arithmetic mean) for the entire period to potentially indicate colder groundwater inflows.

The U.S. Geological Survey collected low-altitude airborne thermal infrared data and visual imagery via a multirotor, small unoccupied aircraft system deployed from the northern bank of Oh-be-joyful Creek and adjacent to the Peeler fault, approximately 6 kilometers northwest of the town of Crested Butte, in Gunnison National Forest, Colorado, on August 17, 2017. Thermal infrared still images were collected in jpg and radiometric tiff formats, and non-radiometric thermal infrared video was collected. The radiometric thermal infrared still images were compiled automatically into a larger stitched image (orthomosaic). Visual imagery was collected in jpg format, and the images were compiled automatically into a larger...
The U.S. Geological Survey (USGS) collected low-altitude (typically 200-350 ft above land surface) airborne thermal infrared, and visual imagery data via a multirotor, small unoccupied aircraft system (UAS or ‘drone’) deployed along the river corridor encompassing two U.S. Geological Survey Next Generation Water Observing Systems (NGWOS) stream gage locations near Claryville, NY, USA. One site is the West Branch Neversink River at Claryville, NY (USGS station number 01434498) and the Neversink River at Claryville, NY (USGS station number 01435000). Beginning in summer 2019 these stations serve as groundwater/surface water instrumentation ‘test beds’ for the NGWOS program. Data collected at the sites include water...
