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 \u2013isotope ratio mass spectrometry technique.
This dataset includes stable isotope ratio and concentration of carbon in seawater during Ulva culture experiments grown at 15C temperatures under various CO2 levels, during May through July 2015.
