동해에서의 최근의 비균질 해수면 상승

Abstract

The recent trend of sea level rise in the East/japan Sea(EJS) is investigated using TOPEX/POSEIDON(T/P) altimetry, long-term tide gauges and thermosteric sea levels(TSL) at stations where long term temperature data are available. The T/P analysis reveals an EJS-averaged increase of about 5.7+-9.1 mm/yr over 9 years, 1992-2001, which is much larger than the global rate of 3.1+-0.4 mm/yr reported by Cabanes et al.(2001). The anomalously high increasing rate of sea level rise in the Ulleung and Yamato basins is apparently due to the large temperature anomaly pattern intensified by eddy activity, which seems to be related to decadal variaitions of heat anomaly in the Northwest Pacific Ocean.
