pH values from ROV survey PS122/4_46-174 on 2020-07-10, survey 2@en

pH values were obtained using a SBE18 pH sensor (Seabird) mounted on the remotely operated vehicle (ROV) during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition between November 2019 and September 2020. The values were derived from the sensor voltages using the same calibration during the entire expedition.2019年11月至2020年9月的北极气候研究多学科漂流观测站（Multidisciplinary drifting Observatory for the Study of Arctic Climate, MOSAiC）考察任务期间，搭载于遥控水下机器人（remotely operated vehicle, ROV）的Seabird品牌SBE18型pH传感器采集得到水体pH值。本次考察全程采用统一校准方案，基于传感器输出的电压信号推算得到上述pH测量值。
