VARIABLES / PARAMETERS:
| Dissolved Inorganic Carbon |
|---|
| Abbreviation: |
DIC |
| Observation type: |
discrete |
| In-situ / Manipulation / Response variable: |
In-situ observation |
| Measured or calculated: |
Calculated |
| Detailed sampling and analyzing information: |
Two different methods have been used to determine the dissolved inorganic carbon content of seawater samples at IOS: gas chromatography and coulometry. There is little information regarding the analyses prior to 1992, especially those samples from the early NOGAP cruises 1986-71, 1987-70 and 1987-71. Samples from these cruises where analyzed by gas chromatography. On later cruises DIC analyses were conducted coulometrically. Samples analyzed after late 1989 were analyzed with SOMMA (Single-Operator Multi-Metabolic Analyzer) systems (Johnson et al., 1993). |
| Total alkalinity |
|---|
| Abbreviation: |
TA |
| Observation type: |
discrete |
| In-situ / Manipulation / Response variable: |
In-situ observation |
| Measured or calculated: |
Measured |
| Type of titration: |
potentiometric titration |
| Cell type (open or closed): |
open, closed |
| Curve fitting method: |
Samples for total alkalinity were determined by software-controlled potentiometric titrations using combination pH electrodes and dilute hydrochloric acid dispensed by automated burettes. Total alkalinity was determined following the closed-cell method described by Millero et al. (1993) until 1999 and using open-cell titrations after that date. |
