2009~2012年南海海洋断面科学考察CTD温盐观测数据集

CTD observation dataset of scientific investigation over the South China Sea(2009–2012)

现场水深、水温、盐度是海洋水文观测的基本要素。CTD温盐深仪是用于测量深度以及温度和盐度垂直变化的自记仪器。南海海洋断面科学考察在2009~2012年春、夏、秋、冬四个不同季节共执行4个多学科和交叉学科的综合考察航次,利用SBE911Plus CTD通过断面观测方式观测温度、电导率、深度、浊度等,综合应用物理海洋学理论规范化处理盐度、密度、声速等,形成本数据集。

In situ water depth,temperature,and salinity are base items of sea observation.Conductivity-temperature-depth(CTD)is the self-recording instrument which is used to measure the depth,the vertical changes of temperature and salinity.Scientific investigation over the South China Sea has explored four multi-disciplinary and inter-disciplinary voyages through four different seasons from 2009 to 2012.The SBE911Plus CTD is used to measure water temperature,conductivity,depth,turbidity and so on,by sectional observation.Physical oceanography theory is used to normalize salinity,density,and sound speed to form this dataset.
