Hydrographic data from ROV survey PS122/4_46-177 on 2020-07-11, survey 2

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、温度和压力由滑翔器重载CTD（Glider Payload CTD，型号SBE GPCTD，SeaBird公司）测量。氧频率由氧光极（oxygen optode，型号SBE 43F DO，SeaBird公司）测量。这两种仪器均安装在遥控潜水器（remotely operated vehicle，ROV）的传感器滑架上，用于2019年11月至2020年9月期间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。数据采用制造商校准值。TEOS-10的吉布斯海水（Gibbs SeaWater，GSW）海洋学工具箱被用于推导其他水文数据。氧频率到溶解氧浓度的转换采用OOI L2数据产品DOCONCF（Vardaro，2014）完成。
