Separated sieved size fractions (Sheet 4) were weighed in 94 samples. Samples were weighed using an A & D semi-microbalance (standard deviation of 0.1 mg)

Core samples were washed over a 38µm sieve and dried in an oven at 40°C. Planktic foraminifera species and genera abundance counts were made on 49 samples.

A representative split of 356 washed samples (>38µm) was analysed for foraminifera size. Size parameters of randomly oriented foraminifers were measured using a Malvern...

The ocean biological pump is the mechanism by which carbon and nutrients are transported to depth. As such, the biological pump is critical in the partitioning of carbon dioxide...
