中国第4次北极科学考察(2010年)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4次北极考察CTD观测数据，调查时间为2010年7月10日-9月8日,本航次调查点144个。数据内容包括站位编号、经度、纬度、探测深度、海水温度、压强、盐度等数据。CTD (Conductance, Temperature, Depth) specifically refers to a marine profiling instrument used to detect seawater temperature, salinity, depth and other related oceanographic parameters. The measurement procedure is as follows: lower the shipboard CTD profiler into seawater at a specified depth at a given winch speed via a winch system, then retrieve the instrument back to the deck. A marine section survey is completed by deploying such CTD profilers. CTD is an important tool for profile measurement of marine environmental parameters. This dataset contains CTD observation data from the 4th Chinese National Arctic Research Expedition. The survey period was from July 10 to September 8, 2010, with a total of 144 survey stations in this cruise. The dataset includes data such as station number, longitude, latitude, detection depth, seawater temperature, pressure, salinity and other related parameters.
