Short summary

Cobalt has the smallest oceanic inventory of all known inorganic micronutrients, and hence is particularly vulnerable to influence by internal oceanic processes. The stoichiometry of cobalt was studied in the North Atlantic, and interpreted with regard to the context of Redfield theory with a focus on biological uptake, scavenging, and the coupling between dissolved and particulate phases. The stoichiometry of cobalt accelerated towards the surface due to increased biological activity and use.
