Abstract

Eppley urged that the naturally produced ratio-isotope 234Th be carefully evaluated as a tracer for export new production. 234Th might be ideal for this purpose because it is produced at a known rate in the water column, it has a strong affinity for particles, its half-life (24d) is appropriate for upper ocean carbon cycling, and because it can be analyzed at sea. We studied this tracer in Monterey Bay which is an ideal location because there is a large seasonal signal in primary and new productivity.
