Ice Tethered Profiler 136 Data Data from ITP136 deployed in September 2022
Last buoy status on 2023/10/2 47 UTC : temperature = -0.9375 °C, battery = 10.517 V Last position on 2023/10/2 47 UTC : 76.467° N, 126.5557° W Last profile (number 1481) on 2023/9/27 602 UTC Last profile mean motor current = 212.4798 mA, mean battery = 8.4094 V Last profile depth: minimum = 756.3407, maximum = 759.9855 m Last profile temperature: minimum = 0.35901, maximum = 0.36462 °C Last profile salinity: minimum = 34.8507, maximum = 34.8512 Last profile dissolved oxygen: minimum = NaN, maximum = NaN μmol/kg Last SAMI pCO2 sample (number 13416) on 2023/10/1 220018 UTC Last pCO2 = 504.3807 μatm Last SAMI ODO sample (number 13417) on 2023/10/1 220026 UTC Last uncorrected Dissolved Oxygen = 472.116 μmol/kg Last SAMI PAR sample (number 13418) on 2023/10/1 220034 UTC Last PAR = 7.9502 μmol/s/m^2 The raw GPS buoy location data are available in an ASCII file: itp136rawlocs.dat Depth averaged profiler data files (with interpolated location) and time series SAMI data are available in two formats: ITP136 was deployed on a 1.2 m thick ice floe in the Beaufort Sea on September 25, 2022 at 79° 10.6 N, 140° 14.4 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2022 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, a Tethered Ocean Profiler (TOP5), a US Army Cold Regions Research and Engineering Laboratory (CRREL) Seasonal Ice Mass Balance Buoy 3 ,and a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB48) were also installed. The ITP includes a dissolved oxygen sensor, is operating on a fast sampling schedule of 4 one-way profiles between 7 and 760 m depth each day and includes a fixed SAMI PCO2 with ODO and PAR at 5 m depth.
