Reference Material Batch 14

This batch was designed to be the basis of a collaborative study in the measurement of total dissolved inorganic carbon. The basic batch (14A) was prepared normally, subsequent batches were prepared by spiking the original batch with a solution of sodium bicarbonate to obtain higher levels of total carbon.

Alkalinity was not measured on this batch.

Nutrient levels were not measured on this batch. They are probably comparable to other batches as the water has roughly the same oceanic source.
