They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer standardized with IAPSO standard seawater 2-3 months after collection. For details see document QF2024-024_SAL*.xlsx. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. Total alkalinity (ALK) was determined by potentiometric titration. Complete documentation on DIC, ALK analysis and precision estimates can be found in the Metadata Excel spreadsheet QF Cruise 2024-024 DIC Alk*.xlsx. References: 1.
