%X On November 15, 2002, China's 19th Antarctic scientific expedition started from Shanghai. On January 14, 2003, China began to carry out ocean exploration in Prydz Bay and the ice margin of the Emory ice shelf in Antarctica. Physical oceanography, marine chemistry, marine biology and carbon cycle related observations of 45 stations in the three sections of the ice margin section of the Emory ice shelf and the Prydz Bay shelf area were completed. In the survey area of Prydz Bay in the South Ocean, due to the poor quality of markiii-ctd data, the seabird sbe-25ctd provided by Haiyang No.1 Institute was bundled on the protection frame of markiii-ctd during the section survey. In this way, the two CTD measuring instruments were lowered at the same time for the whole survey. Seb-25ctd obtained high-quality valuable data to supplement the markiii-ctd data. During the field survey, the probe The lowering speed is controlled at 1. 0 m / s, from the data measured by two instruments (better data of mark iii-ctd), the change trend of the data curve is very similar, and the temperature and salinity changes of the two probes are basically the same. This data set is the measurement data of markiii-ctd and sbe-25 CTD of Prydz Bay and Emory ice shelf during the 19th Antarctic expedition of China from 2002 to 2003.
