- Parameter or Variable: TCARBN; Abbreviation: TCARBN; Unit: UMOL/KG; Controlled vocabulary name: DISSOLVED INORGANIC CARBON (DIC); Observation type: discrete; In-situ / Manipulation / Response variable: in-situ; Detailed sampling and analyzing information: Dissolved Inorganic Carbon in µmol/kg. Measured on discrete samples by coulometry with a UIC Inc CM-5010 coulometer for the years 2020 and 2021, and with a UIC Inc CM-5017 coulometer for the year 2022. Samples are drawn into borosilicate glass bottles and the stopper is sealed with grease. Samples are preserved with HgCl2 saturated, kept in the dark in a cool location and returned to the laboratory for coulometric determination. The system is calibrated by 99.998 % CO2 gas at known temperature and pressure with two stainless steel loops of known volumes. Dickson CRM are used..
- Parameter or Variable: Total Alkalinity; Abbreviation: ALKALI; Unit: UATM; Controlled vocabulary name: Total Alkalinity; Observation type: discrete; In-situ / Manipulation / Response variable: in-situ; Detailed sampling and analyzing information: Measured on discrete samples by an open-cell potentiometric titration by HCl 0.1 M with a Metrohm titrator 888 Titrando.
