摘要

An 18-year-long (1981-1998) study was conducted in Hainan Island warnters (22°20'N, 110°39′E) to determine the relationship between δ18O in skeletal aragrnonite carbonate and sea surface temperature (SST) in porites lutea of reef-building rncorals. δ18O values in skeletal aragonite carbonate were measured by means of mass rnspectrometry. Coral samples grew at 5m depth at Longwan Bay. Monthly measurernments of the SST from 1960 to 1998 were taken at Qinglan Bay adjacent to the place rnof the collected samples. The thermometer shows that SST=-4.16 δ18OpDB + 4.9rn(r=0.80) and dδ18O/dT=-0.24 permil/°C. The δ18O thermometer is strongly influrnenced by the rainfall and runoff. Using the thermometer, the SST in the past hundred rnyears with monthly resolution will be reconstructed and the climatic change in the rnnorthern area of South China Sea will be hindcasted
