Summary

Increased concentrations of carbon dioxide in the atmosphere lowers the ocean pH, which may have effects on phytoplankton species that form the basis of food chains in the ocean. The researchers determined that lower pH lowers iron uptake by phytoplankton. They determined that pH does not alter phytoplankton food update, and that it is the increased difficulty in separation of iron from colloid species
