Sediment PIC concentration profiles were determined from dried and ground sediment powder. Splits were weighed into 10 mL exetainer test tubes (5-20 mg) and acidified with 10% phosphoric acid. The evolved CO2 was measured using a Picarro 2131i. Total CO2 in the Picarro analysis was standardized by running known masses of optical grade calcite standard material.
