ABSTRACT

Oxygen isotope values of low-growth coral (<5 mmyr) skeletons may reflect kinetic effects, which is problematic for sea surface temperature (sst) reconstruction. here, we report a srca-based sst reconstruction temperate Porites coral collected from Kyushu, Japan, near the northern latitudinal extent of hermatypic corals. Results indicate that Sr/Ca variations in a low-growth coral remain independent from growth rate, in contrast to the oxygen isotope ratios of the same coral.
