한려해상국립공원의 물리해양학적 특성

다국어 초록 (Multilingual Abstract)

We investigated physical oceanographic conditions seasonally varying in Hallyeohaesang National Park. Mean water temperatures were 14oC, 20oC and 11oC in spring, autumn and winter, respectively so that there was no vertical gradient of temperature. However, they were 22oC at the surface layer and 16oC at the bottom layer in summer, suggesting that stratification was formed. Mean salinities were 33psu in spring, autumn and winter so that there was no vertical gradient of salinity. However, they were 32psu at the surface layer and 33psu at the bottom layer in summer, suggesting that stratification was formed. On the other hand, this area indicated a different water mass in summer from the other seasons because of the inflows of the outer sea water as well as the Seomjin River freshwater. In particular, the cold water appearing in summer near Geojedo coastal waters turned out to be originated from the Bottom Cold Water of the Korean Strait. In addition, in this area the northerly wind mostly prevailed, except for the southerly wind in summer, and there was a scarce precipitation except for the spring.
