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.
