Millennial rates of shore platform erosion in Dokdo, South Korea

The exposure ages of samples collected from the shore platforms along volcanic islands (Dokdo) in the middle of the East Sea range from the mid-Holocene(ca. 4 ka) to the last century (ca. 0.1 ka). The large range in ages along the outer platform edges may be related to stochastic, differential,and mechanical wave erosion. We also calculated the rates of vertical lowering from the 36Cl concentrations of the platform surfaces, yielding a maximum rate, excluding outliers, of 0.68 mm/yr (Geoscience Journal, in press)
