Ice Tethered Profiler 136 Data Data from ITP136 deployed in September 2022
Last buoy status on 2023/12/4 130047 UTC : temperature = -9.5 °C, battery = 10.469 V Last position on 2023/12/4 130047 UTC : 73.4882° N, 135.5933° W Last profile (number 1735) on 2023/12/4 1202 UTC Last profile mean motor current = 224.5979 mA, mean battery = 8.3452 V Last profile depth: minimum = 195.2841, maximum = 759.9793 m Last profile temperature: minimum = -1.4464, maximum = 0.73688 °C Last profile salinity: minimum = 32.5699, maximum = 34.8528 Last profile dissolved oxygen: minimum = 296.1827, maximum = 340.739 μmol/kg Last SAMI pCO2 sample (number 15705) on 2023/12/4 120018 UTC Last pCO2 = 602.4413 μatm Last SAMI ODO sample (number 15706) on 2023/12/4 120026 UTC Last uncorrected Dissolved Oxygen = 475.218 μmol/kg Last SAMI PAR sample (number 15707) on 2023/12/4 120034 UTC Last PAR = 2.6447 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.
