The rock coast of Korea
The rocky shores of the east and west coasts of Korea have distinctly different geomorphologies. Tidal processes dominate coastal landform development on the west coast, facing the Yellow Sea, while wave processes are more important on the east coast. This gives rise to broad differences in the nature of rocky landforms between these coastlines. With the exception of coastal terraces, there is limited understanding of rock coast systems in South Korea owing to a lack of quantitative analysis. In particular, wide shore platforms along the west coast have been interpreted as inherited features from the Last Interglacial or earlier stages, but the chronology of their development remains poorly constrained and understood because of insufficient investigation. Recently, cosmogenic surface exposure dating has been successfully applied to these platforms, providing new information on their development and offering the possibility of making better predictions of future coastal change. The absolute dating of contemporary and inherited rock coast landforms should help to better constrain the histories of relative sea-level change and coastal morphodynamics in Korea.
Figures & Tables
Rocky landforms dominate large portions of the world's coast. Cliffs and shore platforms form spectacular landscapes, yet when compared to other landforms they are relatively unstudied with many contemporary controversies dating back to the mid-nineteenth century. The past decade has seen a reinvigoration of research driven by advances in technology that now enable precise measurements of erosion to the micron scale and quantification of wave energy onto and through cliff edifices to be made, as well as being able to directly date rock surfaces. In order to integrate this diverse range of research this volume's regional approach first integrates the latest data with longstanding theory and then analyses this research through the boundary conditions that exist in each area. The volume brings together the research leaders in the field; includes chapters on nearly all the major rock coasts of the world and identifies future research needs.
