Abstract
This study was carried out to understand the characteristic distributions of water temperature and salinity in accordance with seasons atound the Tongyeong and Geoje, based on a cluster analysis. Water temperatures in coastal areas were $1-2^{\circ}C$ higher than those in open seas when in the spring, autumn and winter. In particular, a south-northward isothermal line was established at the bottom layer in the winter of 2014, unlikely to the surface layer. In addition, a south-northward isohaline was also established at the bottom layer in the winter of 2013. Therefore, we recognized that a moving pattern of water masses has also a difference since forming directions of those lines were not equivalent with each other between the surface and bottom layers. In contrast, stratification appeared in the summer with a roughly difference of water temperature of $10^{\circ}C$ and a salinity of 2-10 psu between the layers. A cluster analysis indicated that the southeastern coastal waters have three distinct water masses, even though some complicated situations exist due to the seawater inflow from the outside. However, the result of a cluster analysis turned out quite reasonable because the result of a regression analysis proved that it is appropriate, just except for the timing of a south-northward front formation.
