his dataset contains temperature data acquired between June 2019 and September 2020 with an array of 31 autonomous temperature probes installed in smoker orifices, cracks or patches of diffuse hydrothermal venting. We used 5 types of probes (HTW, HTWN, HTNKE, LTW and LTGrad). Probes locations, acquisition parameters and clock drift values (UTC-timeprobe) are listed in the metadata file.
|Utilisation||EMSO data are published without any warranty, express or implied. The user assumes all risk arising from his/her use of EMSO data. EMSO data are intended to be research-quality and include estimates of data quality and accuracy, but it is possible that these estimates or the data themselves contain errors. It is the sole responsibility of the user to assess if the data are appropriate for his/her use, and to interpret the data, data quality, and data accuracy accordingly. EMSO welcomes users to ask questions and report problems to the contact addresses listed in the data files or on the EMSO web page.|
Sensor setup - Test and calibration
All probes are calibrated in time before deployment, probe time adjusted to UTC time. Temperature readings of WHOI probes are checked at IPGP after recovery and before deployment using an oven in the laboratory. NKE probes are sent back to factory every 3-4 years for battery change and calibration. Clock drift after recovery is not implemented in data but listed in the metadata file.
