This dataset contains temperature data acquired between june 2022 and july 2023 with an array of 33 autonomous temperature probes installed in smoker orifices, cracks or patches of diffuse hydrothermal venting. We used 7 types of probes (HTW, HTWN, HTNKE, LTNKE, LTW, LTI and LTGrad). Probes locations, acquisition parameters and clock drift values (UTC-timeprobe) are listed in the metadata file. Temperature data are provided for each deployed instrument as one or two text files, uncorrected for clock drift.
