中国第29次南极科学考察(2012-2013年)长城站近岸水域温盐观测数据

海水的温盐决定了海水的密度，适宜的温度和盐度是海洋生物生存、洄游和繁殖的基本条件，海洋的各种现象和过程都与海水的盐度和温度的时空分布直接或间接相关。温度、盐度、深度是海洋调查的基本参数，主要观测仪器是CTD。 本数据为第29次南极考察南极长城站附近海域CTD观测数据，观测时间为2012年12月，观测断面位于长城站附近的长城湾和阿德雷湾，共包括10个站位，数据内容包括站位编号、经度、纬度、测量时间、深度、温度和盐度。Seawater temperature and salinity determine the density of seawater. Suitable temperature and salinity are basic conditions for the survival, migration and reproduction of marine organisms. Various marine phenomena and processes are directly or indirectly related to the spatiotemporal distribution of seawater temperature and salinity. Temperature, salinity and depth are fundamental parameters for marine surveys, and the primary observational instrument is CTD. This dataset comprises CTD observational data acquired during the 29th Antarctic Research Expedition in the waters adjacent to the Great Wall Station, Antarctica. The observations were conducted in December 2012, with the survey transects located in Great Wall Bay and Ardley Cove near the Great Wall Station, totaling 10 sampling stations. The dataset includes station ID, longitude, latitude, measurement time, depth, temperature and salinity.
