Short summary
We analyze data-constrained state estimates of the global marine iron cycle, a key control on the ocean's biological carbon pump. We develop new techniques for counting the iron's number of passages through the biological pump and link this number to the ocean's natural iron fertilization efficiency. We find that the majority of iron is not biologically utilized before being scavenged, and we identify the central equatorial Pacific as having the highest iron fertilization efficiency.
