Hydrographic data from ROV survey PS122/2_22-45 on 2020-01-28, survey 1

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温盐深仪（Glider Payload CTD，SBE GPCTD，海鸟公司）测得。氧气频率通过光极式溶氧传感器（oxygen optode，SBE 43F DO，海鸟公司）进行测量。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，上述两台仪器均安装于遥控水下机器人（remotely operated vehicle，ROV）的传感器滑橇上。所有数据均采用厂商原厂标定参数完成校准，依托TEOS-10标准下的Gibbs海水海洋学工具箱（Gibbs SeaWater，GSW）推导得到其余水文数据。氧气频率至溶解氧浓度的转换流程采用OOI L2级数据产品DOCONCF实现，相关方法源自Vardaro（2014）的研究成果。
