Coral skeletal Pb : Ca and Ba : Ca both increased dramatically. Pb : Ca ratios are very sensitive to biomass burning on Lanyu Islet while Ba : Ca generally respond to rainfall variations except in case of instantaneous flooding. The method presented here provides a quantitative technique for identifying human effects that can be used for coastal land management and offers a way to study the environment during prehistoric times, where no written records are available. © 2015 Association for the Sciences of Limnology and Oceanography |
