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...

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.
