This dataset contains temperature data acquired between june 2021 and june 2022 with an array of 32 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. Data are provided for each deployed instrument as one or two text files, uncorrected for clock drift: temperature data.
