Ice Tethered Profiler 94 Data Data from ITP94 deployed in October 2019
Last buoy status on 2020/8/17 230027 UTC : temperature = 1.17 °C, battery = 10.5 V Last position on 2020/8/18 80159 UTC : 77.9375° N, 10.5128° W Last profile (number 487) on 2020/8/18 533 UTC Last profile mean motor current = 100.43 mA, mean battery = 11.0755 V Last profile depth: minimum = 212.1514, maximum = 212.1514 m Last profile temperature: minimum = 0.50367, maximum = 0.50367 °C Last profile salinity: minimum = 34.6105, maximum = 34.6105 Last profile dissolved oxygen: minimum = 6.9524, maximum = 6.9524 μmol/kg The raw GPS buoy location data are available in an ASCII file: itp94rawlocs.dat Depth averaged profiler data files (with interpolated location) are available in two formats: ITP94 was deployed on a 0.7 m thick ice floe in the Transpolar Drift on October 7, 2019 at 84° 59.7 N, 135° 5.4 E in collaboration with the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition from the Russian Research Vessel Federov as a contribution to the Hybrid Arctic/Antarctic Float Observation System (HAFOS). On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB), a Seasonal ice mass balance buoy, a Meteorological sled, Spectral radiometer and AWI snow buoy were also installed. The ITP includes a dissolved oxygen sensor and bio-optical sensors and is operating on a pattern profiling sampling schedule including one full one-way profile between 7 and 760 m depth every 1.5 days.
