Autonomous temperature probes, data from the EMSO-Azores observatory, 2017-2018

this dataset contains temperature data acquired between july 2017 and august 2018 with an array of 27 autonomous temperature probes installed in smoker orifices, cracks or patches of diffuse hydrothermal venting.we used 6 types of probes (htw, htwn, htnke, ltw, ltnke and ltibutton). probes locations, acquisition parameters and clock drift values (utc-timeprobe) are listed in the metadata file "sensor metadata"operating parameters : temperatures are recorded at a frequency of: 1 meas. per 1 to 15 minutes (htw, htwn, htnke probes and ltw probes); 1s to 1 minute (ltnke probes); and 2 hours (ltibutton).sensor metadata : high-temperature whoi probes (htw) contain of 2 j-type thermistors in their rod tip connected to 2 temperature data-loggers (named a & b), 2 data recordings are thus available for each probe. htw probes record temperatures up to 415°c with an accuracy of ± 1.1°c, a resolution of 0.25°c at 375°c and a clock drift of about 1min per month.new high-temperature whoi probes (htwn) contain 1 temperature data-logger and 1 attitude logger to measure absolute orientation (tilt) and acceleration. the thermocouple in their rod tip can be j or t-type. we mostly use j-type thermocouples. these record temperatures up to 450°c, with an accuracy of ± 0.6°c, a resolution of 0,03°c and a clock drift of about 1min/year.high-temperature nke probes (htnke) record temperatures up to 450°c, with an accuracy of ±0.5°c, a resolution of 0.1°c and a clock drift of about 1min/month.low-temperature whoi probes (ltw) record temperatures up to 125°c, with an accuracy of ±0.22°c, a resolution of 0.025°c and a clock drift of about 1min per month.low-temperature nke probes (ltnke) record temperatures up to 100°c, with an accuracy of ±0.5°c, a resolution of 0.12°c at 60°c and a clock drift of about 1min/month.low-temperature ibutton probes (ltibutton) record temperatures up to 85°c, with an accuracy of ±0.5°c, a resolution of ±0.5°c and a clock drift of about 1min/month.all probes are calibrated in time before deployment, probe time adjusted to utc time. temperature of probes is checked after recovery and before deployment. clock drift after recovery is not implemented in data.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 "sensor metadata"data management real time data transmission: no data storage in the communication and storage unit (costof2): no data storage in the instrument: full

本数据集包含2017年7月至2018年8月期间采集的温度数据，数据由27个自主式温度探头在烟囱孔口、裂缝或扩散型海底热液喷口区域收集而成。本实验使用了6种类型的探头（HTW、HTWN、HTNKE、LTW、LTNKE和LTIBUTTON）。探头的位置、采集参数以及时钟漂移值（UTC时间-探头时间）均详细列于名为“传感器元数据”的元数据文件中。操作参数：温度记录的频率为：每1至15分钟记录1次测量值（HTW、HTWN、HTNKE探头和LTW探头）；1秒至1分钟（LTNKE探头）；以及每2小时（LTIBUTTON探头）。传感器元数据：高温WHOI探头（HTW）在其探头尖端装有2个J型热敏电阻，连接至2个温度数据记录仪（命名为A和B），因此每个探头提供2次数据记录。HTW探头可记录高达415°C的温度，精度为±1.1°C，在375°C时的分辨率为0.25°C，时钟漂移约为每月1分钟。新型高温WHOI探头（HTWN）包含1个温度数据记录仪和1个姿态记录仪以测量绝对方位（倾斜）和加速度。探头尖端的热电偶为J型或T型，我们主要使用J型热电偶。这些探头可记录高达450°C的温度，精度为±0.6°C，分辨率为0.03°C，时钟漂移约为每年1分钟。高温NKE探头（HTNKE）可记录高达450°C的温度，精度为±0.5°C，分辨率为0.1°C，时钟漂移约为每月1分钟。低温WHOI探头（LTW）可记录高达125°C的温度，精度为±0.22°C，在60°C时的分辨率为0.025°C，时钟漂移约为每月1分钟。低温NKE探头（LTNKE）可记录高达100°C的温度，精度为±0.5°C，在60°C时的分辨率为0.12°C，时钟漂移约为每月1分钟。低温iButton探头（LTIBUTTON）可记录高达85°C的温度，精度为±0.5°C，分辨率为±0.5°C，时钟漂移约为每月1分钟。所有探头在部署前均进行了时间校准，并将探头时间调整为UTC时间。探头恢复后及部署前，对WHOI探头的温度读数进行了检查，使用实验室中的烤箱在IPGP进行。NKE探头每3至4年返回工厂更换电池并进行校准。恢复后的时钟漂移未在数据中实现，但已在“传感器元数据”元数据文件中列出。测试和校准：所有探头在部署前均进行了时间校准，并将探头时间调整为UTC时间。WHOI探头的温度读数在恢复后及部署前使用实验室中的烤箱在IPGP进行了检查。NKE探头每3至4年返回工厂更换电池并进行校准。恢复后的时钟漂移未在数据中实现，但已在“传感器元数据”元数据文件中列出。数据管理：实时数据传输：否；通信和存储单元（Costof2）中不进行数据存储；仪器中存储数据：全部。
