Oxygen isotope data has NOT been corrected for the acid fractionation difference (acid-alpha) between standards (calcite) and coral samples (aragonite). Prior to 1895/1896 the data exhibits a kinetic overprint.

Reliability of coral isotope records from the Western Pacific Warm Pool: A comparison using age-optimized records

No calibrations, two cores are part of this study (see GU99NAU01); Oxygen isotope data has NOT been corrected for the acid fractionation difference (acid-alpha) between standards (calcite) and coral samples (aragonite). Slow growing portion of the record (1898-1939) shows a strong kinetic overprint

continuous, 2 mm discrete samples, but growth rate went from 8mm/yr to 21mm/yr and the lower, slow growing portion of the record (1898-1939) shows a strong kinetic overprint.  Due to slow growth and early morphological changes 1900 is extremely truncated.
