中国第1次南极科学考察(1984年)南大洋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1次南极考察的南大洋CTD观测数据，调查时间为1985年1月20日-2月12日,本次调查点33个。数据内容包括站位编号、经度、纬度、测量时间、水深、最大观测深度等数据。

CTD (Conductance, Temperature, Depth) specifically denotes a profiling instrument used to detect parameters such as seawater temperature, salinity and depth. The measurement procedure involves lowering the shipboard CTD profiler into seawater at a designated depth at a controlled winch speed via a winch system, then retrieving it back to the deck. A marine section survey is conducted by deploying CTD profilers. CTD is a critical tool for profiling measurements of marine environmental variables.

This dataset comprises CTD observation data from the Southern Ocean collected during China's First Antarctic Expedition. The survey was carried out from January 20 to February 12, 1985, with a total of 33 survey stations. The dataset includes information such as station number, longitude, latitude, measurement time, water depth, maximum observed depth and other relevant data.
