Description

This dataset includes DIC and alkalinity, with additional carbonate calculations, from an experiment using Globobulimina.

Methods & Sampling

Experimental conditions inside Biospherix C-chambers were controlled with Biospherix ProO2 and/or ProCO2 sensors and controllers. These Biospherix systems have 2% precision. Due to resource constraints, Treatments A and E lacked CO2sensors; Treatments C and D lacked O2 sensors. Alkalinity was determined using Gran titrations of 1 ml samples. DIC was determined manometrically on ~5-ml samples using an automated vacuum extraction system.
