AB  - This data is CTD observation data from the open sea of Great Wall Bay, mainly including deep-sea temperature and salinity data, with three observation elements including seawater depth, seawater temperature, and seawater salinity. As an important marine basic data, CTD data can provide data support for the study of seawater physical and chemical properties, water layer structure, and water mass movement. The CTD (Conductivity, Temperature, Depth) measurement system, commonly known as the Temperature Salt Depth system, is used to measure the three basic physical parameters of water, namely conductivity, temperature, and depth. It can also calculate other physical parameters such as sound velocity based on these parameters. The CTD measurement system is an essential tool for ocean surveys, and large CTDs also come with water collectors. The measurement method is to lower the CTD profiling instrument cut by the ship at a certain winch speed until it reaches a specified depth of seawater, and then retract it back onto the deck. In marine surveys, a CTD profiler is usually deployed to complete a cross-sectional survey of the ocean.
