- •
Titration alkalinity was 3–38% higher than alkalinity calculated from DIC and pH.
- •
Excess alkalinity in pore water increased gradually going deeper into the sediment.
- •
Anoxic decomposition of organic matter has led to production of organic alkalinity.
- •
Bacterial reduction of sulphate was the main source of non-carbonate inorganic bases.
