Abstract:
A series of Tpop bottom temperature sensors manufactured by the University of Rhode Island (contact: Randolph Watts <randywatts@uri.edu>) were deployed during legs 2, 3 and 5 of MOSAiC, in the deep Central Actic, from January 2020 to September 2020. They recorded the temperature at approximately 10 m above the seafloor with an hourly resolution from their deployment till they surfaced automatically on 1 September 2021 and sent their data over iridium. They are provided here calibrated against the MOSAiC ship CTD (Tippenhauer et al., 2023, DOI:10.1594/PANGAEA.959963). Due to a large but of unknown magnitude sensor drift compared to the measured signal, they are here provided entirely de-trended. Any natural, real trend would have been removed by the process. The precision of Tpops 60 and 66 is 10 times that of the others (0.1 mK compared to 1 mK) because they beached in the North Atlantic; the data could be retrieved from the SD card instead of iridium only.
