Continuous thermosalinograph oceanography along RV METEOR cruise track M181@en

Underway temperature and salinity data was collected along the cruise track with two autonomous thermosalinograph (TSG) systems, each consisting of a SBE21 TSG together with a SBE38 Thermometer. Both systems worked independent from each other throughout the cruise. While temperature is taken at the water inlet in about 5 m depth, salinity is estimated within the interior TSG from conductivity and interior temperature. Temperature and salinity were calibrated against CTD data from 5 m depth. For details to all processing steps see Data Processing Report.

本数据集包含沿航迹采集的走航式温盐数据，采集所用设备为两套独立的自主式温盐测量系统（autonomous thermosalinograph, TSG），每套系统均由一台SBE21型温盐计（SBE21 TSG）与一台SBE38型温度计（SBE38 Thermometer）组成。整个航次期间，两套系统始终独立运行。温度数据采集于约5米深度的进水口处，盐度则通过温盐计内部的电导率与内部温度数据估算得到。所获温盐数据均以5米深度处的温盐深剖面仪（Conductivity Temperature Depth, CTD）数据完成校准。有关所有处理步骤的详细信息，请参阅数据处理报告（Data Processing Report）。
