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

Conductivity, temperature, and pressure were measured by a Glider Payload CTD (SBE GPCTD, Seabird). Oxygen frequency was measured by an oxygen optode (SBE 43F DO, Seabird). Both instruments were mounted in the sensor skid of a remotely operated vehicle (ROV) during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition between November 2019 and September 2020. Data use manufacturer calibration. The Gibbs SeaWater (GSW) Oceanographic Toolbox of TEOS-10 was used to derive other hydrographic data. The conversion from oxygen frequency to dissolved oxygen concentration was performed using the OOI L2 data product DOCONCF (Vardaro, 2014).电导率、温度与压力由滑翔机有效载荷CTD（Glider Payload CTD，SBE GPCTD，Seabird公司）测定。氧气频率通过氧气光极传感器（oxygen optode，SBE 43F DO，Seabird公司）完成测量。在2019年11月至2020年9月开展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）考察任务中，两台仪器均安装于遥控水下机器人（remotely operated vehicle，ROV）的传感器滑橇组件上。所有数据均采用制造商原厂校准方案进行校正。本研究依托TEOS-10标准下的Gibbs海水（GSW）海洋学工具箱，推导得到其余水文观测数据。氧气频率至溶解氧浓度的转换过程，通过使用OOI L2级数据产品DOCONCF（Vardaro，2014）完成。
