The international reference material JCp-1 (coral powder) was analyzed with every sample batch (N = 6 in each run) to reveal external reproducibility, which was <0.15% (RSD) or 0.01 mmol/mol. The average Sr/Ca value of the JCp-1 standard from multiple measurements on the same day and on consecutive days was 8.820 mmol/mol, indicating an accuracy <0.20% relative to the average value (8.838 mmol/mol) reported in Hathorne et al. (2013).

The analytical errors for JCp-1 is 0.10% (average 8.828  0.009 mmol/mol, n = 124)
For Sr/Ca, we use reference standard JCp-1. The analytical errors for JCp-1 is 0.18% (average 8.824  0.018 mmol/mol, n = 1146)
Analytical precision and accuracy were determined through repeat measurements of the coral reference material JCp-1 throughout each run. The reproducibility of JCp-1 is 0.20% relative standard deviation (RSD) (n = 2,287), with an average value of 0.01935 g/g ( 0.000038, 1),

Bulk coral powder reference material JCp1 (Okai et al., 2001) with a consensus Sr/Ca value of 0.01932 (0.0002) ppm or 8.838 (0.089) mmol/mol (Hathorne et al., 2013) and an inhouse powder standard (Porites sp.) were both analyzed throughout each run to evaluate measurement precision. Repeat measurements of JCp1 and the inhouse coral powder standard analyzed over a period of 2 years showed very good reproducibility, 0.019291 (0.00004) ppm or 8.824 (0.018) mmol/mol (1, relative standard deviation = 0.18%, n = 1074) and 0.019289 (0.00005) ppm or 8.823 (0.023) mmol/mol (1, relative standard deviation = 0.25%, n = 396), respectively.

The average Sr/Ca value of the JCp-1 standard from multiple measurements on the same day and on consecutive days was 8.855 mmol/mol with a RSD of 0.09%.
