Multi-proxy database of South China Sea temperature change since the last glacial maximum

South China Sea is a marginal sea surrounded by several countries including Taiwan. Oceanographic changes here  directly impact the climate experienced by societies in this region. Studying oceanographic changes here across time scales and climate states will improve mechanistic understanding of climate change process, thus allowing a better future projection that will inform policymakers. Surface ocean temperature is an important metric in Earth climate system. Past changes in ocean temperature can be reconstructed using the geochemical signals in calcite shells of protists (e.g. Mg/Ca and clumped isotope of foraminifera), and the lipids of algae (e.g. UK'37) and marine archaea (e.g. TEX86). These temperature proxies do not always yield the same temperature estimates, due to the differences in the chemistry and ecology of these proxies, as well as their calibrations and biases caused by other non-thermal physiological effects. Therefore, one way to test if these proxies can be used interchangeably as "surface ocean temperature proxy" is to generate a systematic database with multiple temperature proxies in sediment cores.
