by Helen Hill for MIT CBIOMES
The Redfield ratio, the atomic ratio of carbon, nitrogen, and phosphorus (C:N:P) in phytoplankton and deep ocean waters, has often been treated as a constant 106:16:1. A new paper involving several CBIOMES co-authors, among them two from the MIT Darwin Group, presents compelling evidence for what causes this ratio to change within phytoplankton.
