中国第18次南极科学考察(2001年)普里兹湾CTD观测数据

CTD（Conductance电导，Temperature温度，Depth深度），特指一种用于探测海水温度，盐度，深度等信息的探测仪器。测量的方法是由绞车将船裁的CTD剖面仪器按一定的绞车速度下放,直到规定深度的海水中，然后再将其收回甲板上。通过投放CTD剖面仪来完成一个海洋断面调查。CTD是海洋环境要素剖面测量重要工具。

本数据为中国第18次南极考察的普里兹湾海域CTD观测数据，调查时间为2001年12月22日-2002年2月20日,本次调查点68个。数据内容包括站位编号、经度、纬度、测量时间、水深、投掷深度等数据。

CTD (Conductance, Temperature, Depth) specifically refers to a profiling instrument used to detect seawater temperature, salinity, depth and other related parameters. The measurement workflow involves lowering the ship-borne CTD profiler into seawater at a target depth at a controlled winch speed via a winch system, then retrieving the instrument back to the research vessel deck. A marine section survey is completed by deploying such CTD profilers, and CTD is an important tool for profiling measurements of marine environmental variables.

This dataset contains CTD observation data collected in the Prydz Bay during the 18th Chinese National Antarctic Research Expedition. The survey was conducted from December 22, 2001 to February 20, 2002, with a total of 68 survey stations. The dataset includes information such as station number, longitude, latitude, measurement time, water depth, and cast depth.
