Ice Tethered Profiler 138 Data Data from ITP138 deployed in September 2023
Last buoy status on 2023/12/4 70931 UTC : temperature = -15.125 °C, battery = 10.848 V Last position on 2023/12/4 70931 UTC : 79.6545° N, 142.4347° W Last profile (number 88) on 2023/11/7 602 UTC Last profile mean motor current = 138.5696 mA, mean battery = 10.8464 V Last profile depth: minimum = 7.4031, maximum = 759.9987 m Last profile temperature: minimum = -1.5233, maximum = 0.86616 °C Last profile salinity: minimum = 28.0438, maximum = 34.8654 Last SAMI pCO2 sample (number 1737) on 2023/11/7 60010 UTC Last pCO2 = 344.8158 μatm Last SAMI ODO sample (number 1738) on 2023/11/7 60019 UTC Last uncorrected Dissolved Oxygen = 476.439 μmol/kg Last SAMI PAR sample (number 1739) on 2023/11/7 60029 UTC Last PAR = 127.4626 μmol/s/m^2 The raw GPS buoy location data are available in an ASCII file: itp138rawlocs.dat Depth averaged profiler data files (with interpolated location) and time series SAMI data are available in two formats: ITP138 was deployed on a 0.8 m thick ice floe in the Beaufort Sea on September 23, 2023 at 77° 58.2 N, 140° 47.3 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2023 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, a Tethered Ocean Profiler (TOP11), 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 is operating on a fast sampling schedule of 4 one-way profiles between 5 and 760 m depth each day and includes a fixed SAMI PCO2 with ODO and PAR at 5 m depth.
