中国第29次南极科学考察(2012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29次南极考察的普里兹湾海域CTD观测数据，调查时间为2013年1月31日-3月3日,本次调查点63个。数据内容包括站位编号、经度、纬度、测量时间、海水压力、测深、海温、盐度、密度、声速、位温等数据。

CTD (Conductance, Temperature, Depth) specifically denotes a shipboard profiling instrument used to detect seawater temperature, salinity, depth and other marine environmental parameters. The measurement workflow involves lowering the shipboard CTD profiler into seawater at a controlled winch speed until reaching the predetermined depth, then retrieving it back to the research vessel's deck. A marine section survey is completed by deploying such CTD profilers. CTD is an essential tool for profiling measurements of marine environmental variables.

This dataset contains CTD observation data collected in the Prydz Bay during the 29th Chinese National Antarctic Research Expedition. The survey was conducted from January 31 to March 3, 2013, with a total of 63 survey stations. The dataset includes parameters such as station ID, longitude, latitude, measurement time, seawater pressure, water depth, in-situ seawater temperature, salinity, density, sound velocity, and potential temperature.
