CROZet Natural Iron Bloom and EXport Experiment (CROZEX)

Summary of the project

CROZEX was a complex, multidisciplinary project to examine, from surface to sediment, the causes and consequences of the naturally iron-fertilized annual bloom that forms north of the Crozet Plateau in the southwest Indian Ocean sector of the Southern Ocean. The field phase consisted of a pair of cruises, D285 and D286, funded by SOC Core ship time for the George Deacon Divisions’s (GDD) Core Strategic Project BICEP (Biophysical Interactions and Controls on Export Production).
