The transfer of dissolved organic carbon (DOC) and nitrogen (DON) out of the surface ocean where it is produced to storage in the ocean's interior creates one of the largest reservoirs of reduced carbon and organic nitrogen on earth. In nutrient-depleted surface waters of the oligotrophic ocean, dis
