中国第8次北极科学考察(2017年)CTD观测数据
收藏资源简介:
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8次北极考察CTD观测数据,调查时间为2017年7月28日-9月25日,本航次调查点76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 type of sounding instrument used to detect seawater temperature, salinity, depth and other relevant oceanographic information. The measurement procedure involves lowering the ship-mounted CTD profiler at a designated winch speed via a winch into seawater at a specified depth, then retrieving the instrument back onto the deck. An ocean section survey is completed by deploying the CTD profiler. CTD is a critical tool for profile measurement of marine environmental parameters. This dataset comprises CTD observation data collected during the 8th Chinese National Arctic Research Expedition. The survey was conducted from July 28 to September 25, 2017, with a total of 76 survey stations in this cruise. The dataset includes information such as station number, longitude, latitude, measured depth, seawater temperature, pressure, salinity and other related data.
