Latest update: 14 Dec 2024
Short summary
Cobalt is a scarce nutrient required by phytoplankton. We report more than 800 measurements of dissolved cobalt in the South Pacific Ocean, which show high cobalt concentrations in anoxic subsurface waters offshore of Peru. Coastal cobalt sources may be stronger under low oxygen and could fluctuate as climate change is expected to alter the extent of these low-oxygen regions.
