Xiangming uses biogeochemical/geochemical indexes (alkenone unsaturation index U­­­k'37, hydrogen isotope ratio ẟD) to study the past variations of sea surface temperature (SST) and sea surface salinity (SSS). SST and SSS are very important in disclosing the warm and cold climate history of the Earth and therefore, provide necessary benchmarks for predicting future climate change. He is recently working on constructing a global map of ocean surface temperature using U­­­k'37paleotemperature index for MIS M2 event (~3.2 million years ago), to search for the possible causes of this special cooling event.
