This child page contains specific conductance and temperature data collected from a series of temporary shallow drivepoints at Site 11 at Naval Air Station Pensacola, in Florida. The drivepoints were installed along the shoreline of Bayou Grande in six transects consisting of three to four drivepoints each. The drivepoints were hammered by hand into the sandy overburden until refusal in areas of potential groundwater discharge previously identified during a distributed temperature sensing survey. Installation depths below land surface ranged from a minimum of 2.7 feet to a maximum of 5.7 feet. Drivepoints were constructed from 1.25-inch polyvinyl chloride (PVC) well screens with 0.010-inch wide slots. The bottom of each drivepoint was sealed with a threaded PVC point and the top was finished with a PVC slip cap. Specific conductance and temperature sensors with internal data loggers were installed near the bottom of each drivepoint. A second shallower sensor was sometimes installed in a subset of the drivepoints near mid-depth. Data were collected at transects 1-3 from September 2018-September 2022 and from transects 4-6 from June 2019-September 2022. Data was collected at 15-minute intervals at all transects until May 6, 2021, when the interval was changed to 30 minutes.

This data release consists of two datasets, each accessible in its own child page, collected at the North Chevalier Field Disposal Area (Site 11) at Naval Air Station Pensacola in Florida. Site 11 is adjacent to Bayou Grande, which empties into Pensacola Bay. The first dataset consists of fiber-optic distributed temperature sensing data collected from March 13-March 16, 2018. The second dataset consists of specific conductance and temperature data collected from September 12, 2018-September 19,2022 from a series of shallow drivepoints installed along the shoreline at Site 11.

This child page contains fiber-optic distributed temperature sensing data collected from March 13-March 16, 2018 at the North Chevalier Field Disposal Area (Site 11) at Naval Air Station Pensacola in Pensacola Bay in Florida. A fiber-optic cable was run on the bottom of the bay parallel to the shoreline along an approximate 370-meter reach. The cable was installed near the shoreline just far enough offshore that most of it remained submerged at low tide. At the end of the reach, the cable was doubled back and installed parallel to, and approximately one meter offshore, of the first run. At the end of the second run, the cable was run ashore and connected to an Oryx Distributed Temperature Sensing (DTS) system. Near the DTS, several coils of the fiber optic cable were submerged in an ice slurry for the duration of the survey as a quality control measure. Temperature was measured every 15 minutes at one-meter intervals along the length of the cable. The temperature data, which are reported by the instrument as linear fiber distance, were georeferenced using a handheld Global Positioning System (GPS) for the purpose of relating known points in space to the distance along the fiber-optic cable. Additional details of the temperature survey can be found using the link to the companion U.S. Geological Survey (USGS) Scientific Investigations Report.

The United States Geological Survey (USGS) is studying the effects of climate change on ocean acidification within the Gulf of Mexico; dealing specifically with the effect of ocean acidification on marine organisms and habitats. To investigate this, the USGS participated in cruises on the West Florida Shelf and northern Gulf of Mexico regions aboard the research vessel (R/V) Weatherbird II or Bellows, ships of opportunity led by Dr. Kendra Daly, of the University of South Florida (USF) in July and August, 2013. Cruises left from and returned to Saint Petersburg, Florida, but followed different routes. The USGS collected geochemical data pertaining to pH, dissolved inorganic carbon (DIC), total carbon dioxide (TCO2), and total alkalinity (TA) in discrete samples at various depths from predetermined stations. Discrete surface samples were also taken, while in transit, during both cruises.

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.
