Oceanography: A phosphate alternative
Sergio A. Sañudo-Wilhelmy1
Abstract
A major player among the phytoplankton can exploit a source of phosphorus previously thought to be unavailable to it. That ability may provide an ecological advantage in nutrient-depleted regions of the open ocean.
All marine phytoplankton depend on the availability of nutrients, and no nutrient is more important than nitrogen. Although there is an abundant supply of nitrogen in Earth's atmosphere, it is in the form of molecular N2, which cannot be used by phytoplankton and must be 'fixed' before it can be utilized by most living organisms1.
