AB  - This data is the CTD observation data for the waters off the Great Wall Bay, mainly including deep-sea temperature and salinity data. The elements include three observation elements: seawater depth, seawater temperature, and seawater salinity. CTD data, as an important marine basic data, can provide data support for the study of physical and chemical properties, water layer structure, and water mass movement of seawater. 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. Other physical parameters, such as sound velocity, can be calculated based on these parameters. The CTD measurement system is an essential tool for ocean surveys, and large CTDs also carry water samplers. The measurement method is to use a winch to lower the CTD profile instrument cut by the ship at a certain winch speed until it reaches a specified depth of seawater, and then retrieve it back onto the deck. In ocean surveys, a CTD profiler is usually used to complete an ocean cross-section survey
