ID-ICP-MS, an analytical method that combines isotope dilution technique and ICP-MS method had been developed in our laboratory. Trace uranium of the coral samples from the northern area of the South China Sea had been measured to an accuracy of 0.5%. Depended on these results, a high resolution coral U/Ca thermometer for thes area was established. Monthly average SSTs with a precision of ±0.5℃ were attainable by this U/Ca thermometer.
