Abstract
The analysis of the 9-year (1993-2001) long-term sea level in the East/Japan Sea (EJS) revealed that there exist some large sea level (SL) rising rate, two times as high as global sea level rise, of about 6.0 mm/yr in the southern East/Japan Sea. Now 19-year (1993-2011) sea level of satellite data with thermosteric and steric sea level data are examined to how the trend can change in the semi-enclosed basin, EJS. Thermosteric, halosteric, and steric sea levels was computed from various sources of data such as hydrographic, Argo, and XBT data. The sea level data from Topex/Poseidon and Joson satellites have been subject to giving rise to sea level trend. The 13 tidal station data are also examined. Compared with 6mm/yr sea level rising rate from 9 year data (1993-2001), the sea level rising rate for 19 year (1993-2011) in the EJS is found to be about 3.0mm/yr, half as high as the rate for 9 years. This magnitude of SLR rate for 19 years is more or less similar to global mean sea level rising rate. This difference of SLR rate between 9 year and 19 year long data indicates the possibility that long-term component of SLR affect the trend such as tidal and non-tidal origins.The thermosteric and steric sea levels was examined to see if the long-term oscillation such as Pacific decadal oscillation or others may appear in the signal. The peak signal of thermosteric and steric sea levels in the sJapan Sea. Now 19-year (1993-2011) sea level of satellite data with thermosteric and steric sea level data are examined to how the trend can change in the semi-enclosed basin, EJS.
