Methods & Sampling

Samples for delta-13C of dissolved inorganic carbon (DIC) in the seawater were stored in 20 mL glass vials with cone lids to exclude air from samples. Samples were stored at room temperature in low light until prepared for analysis using the exetainer gas evolution technique for DIC (Li et al. 2007). Then, the samples were sent to the University of California, Davis Stable Isotope Facility (UCD-SIF) for analysis using the GasBench –isotope ratio mass spectrometry technique.
