Inorganic nutrients and dissolved oxygen in the Canary Current Large Marine Ecosystem
10 pages, 6 figures Inorganic nutrients increase with depth as a result of the enhanced remineralization of organic matter with aging waters (the time since they were last near the sea surface), and the opposite happens with dissolved oxygen (except within the saturated surface mixed layer).
