To understand long-term variations of Sea Surface Temperature (SST) in inshore and offshore waters of Jeju Island in Korea, long-term data of the shore stations (1924~2009) and the network of serial oceanographic observations (1968~2008) under the National Fisheries Research and Development Institute, Korea were analyzed. The SST in coastal waters of Jeju Island has increased by 1.94oC for the last 86 years. The SST in offshore waters has increased by 1.17oC for the last 41 years. The SST has risen by 0.26oC in inshore and 1.78oC in offshore waters of Jeju Island in summer season. The SST has increased by 4.75oC in inshore and 1.13oC in offshore waters in winter season. Therefore, the annual amplitude of SST has diminished in the waters of JeJu Island between summer and winter season. We speculated that SST increase was driven by the global warming and heated fresh water from the Yangtze River. On the other side, long-term variation of SST in the waters of Jeju Island was quantified by using NOAA/AVHRR satellite data from 1990 to 2008.
