A long-lived Porites coral from New Ireland (2.5°S, 150.5°E), Papua New Guinea, has been analyzed for Sr/Ca and Ba/Ca by laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS). The top 50 years of the core are examined here and compared with instrumental sea surface temperatures (SSTs). For the small range of SST in the warm pool, Sr/Ca shows an unusually large response. The best estimate for the slope of a temperature calibration is –0.23 ± 0.03 mmol/mol per°C. This strong...[Show more]
