The Oceanographic study of the Subarea 48.6 on the SST, SIC, PST, current and wind vector was conducted. The lower SST corresponded to the higher SIC and vice versa. The PST indicates the mixed layer depths in research block5. The currents around the research block 4 and 5 were indicated. It is found out that there is a relationship between the SST and the wind. The CTD vertical profile data collected by Tronio should contribute to developing this oceanographic study.
