- Duplicate Measurements - No information
- CRM Results - Shipboard analyses of batch 29. The CRM certified value was 1902.54 ± 1.05 (n=14). The overall accuracy and precision for the CRMs on both instruments combined was -1.1 ± 0.9 (n=153). Data were corrected for offset.
- Keeling Replicates- Replicate measurements from different PVC bottles tripped at the same depth, along with replicate measurements from the same PVC bottle was within ± 1.9 µmol/kg.
- Alkalinity (Millero-RSMAS) - No adjustment recommended.

- Precision of Duplicate Measurements - No Information.
- CRM Results - 85 CRM measurements made at sea yielded 2173.8 ± 1.6 µmol/kg for Batch 29 and 2190.8 ± 1.7 µmol/kg for Batch 30 on three different cells. This offset was due to changes in the volume of the cells. All TA data have been corrected to laboratory CRM values for each cell and each leg.
- fCO2 (not measured)
- pH (Millero - RSMAS) - We recommend adjusting all spectrophotometric pH values upward by 0.0047 pH units to be internally consistent with the other carbon parameters.
