This submission is an 8 day time history of vertical temperature measurements in Brady observation well 56-1 collected during the PoroTomo field experiment. The data was collected with a fiber-optic DTS system installed to a depth of 372 m below wellhead. DTS installation uses a double-loop set up. Data includes forward length and backward length temperature measurements.

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).

Natural heat is used as a tracer for a variety of physical hydrogeological process, including zones of preferential exchange between groundwater and surface water. Several types of instruments are used to measure the temperature of surface water and saturated sediments. This data release presents the results of fiber-optic distributed temperature sensing (FO-DTS) using temperature sensitive armored cables deployed along the riverbed interface. Data were collected over time (08/06/2015 to 09/24/2015) at 1.01 m spatial resolution along a reach of the Little Wind River, WY, USA. This study reach included an upstream shallow side channel where the cable was exposed to air over several short segments, and a downstream deeper section where the cable was generally installed within 5 m of the bank. The FO-DTS system was setup to collect a temperature measurement along this cable every 40 min; however, solar power to the control unit failed intermittently during the deployment period, especially later in the record, so the data are of inconsistent timestep. The processed data included in this release have been clipped to a cable length and time period of specific interest, as described in the local readme files.

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, individual logging thermistors, and fiber-optic distributed temperature sensing. The latter type of data (FO_DTS) are described and presented here.

Metadata for active distributed temperature survey (DTS) experiments at Guelph, Ontario Canada. This data that this metadata refers to was taken as part of the PoroTomo project. The metadata includes information about status, location, elevation, units, and other metadata.

From June 25 to June 28, 2018, the U.S. Environmental Protection Agency (EPA) collected temperature measurements to help evaluate the thermal properties at two locations along the shoreline of City Lake in Fredericktown, MO. The in-situ temperature of surface water and saturated sediments was monitored to support calculations of seepage flux. Temperature measurements Celsius were collected every 30 minutes at depths of 0.04, 0.15,0.30,0.61, and 0.91 m below the water bottom. The thermal conductivity of saturated sediments was also measured.

Static Pressure and Temperature Log for Brady monitor well SP-2. This data was taken from Well SP-2 which is part of the Brady Hot Springs Geothermal Site. The data contains pressure and temperature vs depth data for RIH (run in hole) Static conditions and POOH (pull out of hole) Static conditions. The data was recorded on 2/18/2015 and measurements reach a depth of 4392 feet.
