Rising trend of relative sea level along the coast of East Asia

The rise or fall trend of the sea level along the coast of East Asia is estimated with different computational methods based on sea‐level data of longer time series collected from 45 tide gauge stations there. The results show that the relative sea level, on average, has been rising along the coast of the whole of East Asia from the early 1950s to the early 1990s. The regional change of sea‐level rise or fall is greater. The sea level along the coast of China, except along the Shandong Peninsula, is rising; the sea level along the coast of the southern islands of Japan and the southern Korean peninsula, as estimated by several methods, is mostly rising, but the rate of rise is very small. The difference between the results estimated in this study and the corresponding results of Barnett along the coast of East Asia is significant. This is mainly because the number of the stations selected by Barnett is relatively small, and the selected stations are concentrated at the southern and northern ends of the region, without data in the middle of the region. The effect of the estimating methods is smaller.
