Hydrographic data from ROV survey PS122/2_18-19 on 2019-12-31, survey 1@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).本数据集采用滑翔机有效载荷温盐深仪（Glider Payload CTD，型号SBE GPCTD，海鸟（Seabird）公司）测量电导率、温度与压强；采用溶氧光极（oxygen optode，型号SBE 43F DO，海鸟公司）测量氧气频率。在2019年11月至2020年9月的北极气候多学科漂流观测站（Multidisciplinary drifting Observatory for the Study of Arctic Climate，简称MOSAiC）科考航次期间，上述两台仪器均安装于遥控无人潜水器（remotely operated vehicle，ROV）的传感器滑橇（sensor skid）上。所有数据均采用厂商校准方案进行标定。本研究采用TEOS-10标准下的Gibbs海水电学（Gibbs SeaWater，简称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，采用OOI L2级数据产品DOCONCF完成（Vardaro，2014）。
