When Phytoplankton Go Hungry
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.

A Model for Nitrogen Fixation in the Presence of Ammonium
Former MIT Darwin Group member Keisuke Inomura, working with MIT CBIOMES investigator Mick Follows, presents a new quantitative model of nitrogen fixation in the presence of ammonium. Continue reading A Model for Nitrogen Fixation in the Presence of Ammonium
Study: Much of the surface ocean will shift in color by end of 21st century
Climate-driven changes in phytoplankton communities will intensify the blue and green regions of the world’s oceans. New work from Darwin researchers Stephanie Dutkiewicz and Oliver Jahn. Continue reading Study: Much of the surface ocean will shift in color by end of 21st century

Understanding Microbial Competition for Nitrogen
The Darwin Project’s Emily Zakem, Stephanie Dutkiewicz and Mick Follows show that physiological constraints and resource competition between phytoplankton and nitrifying microorganisms in the sunlit layer can yield this ocean trait. Continue reading Understanding Microbial Competition for Nitrogen

A review article involving Stephanie Dutkiewicz and Oliver Jahn suggests the diatoms have more diverse roles in carbon cycling than previously understood. Continue reading A More Diverse Role for Diatoms
What you Can Do With a Really Rather Realistic Ocean Model
Helen Hill | Darwin Project
It’s been a decade since the inception of the MIT Darwin Project, an alliance between physical oceanographers, biogeochemists and marine microbiologists at the Massachusetts Institute of Technology (MIT). The goal of Darwin remains to couple state of the art physical models of global ocean circulation with biogeochemistry and genome-informed models of microbial processes to understand the interplay between different elements of the marine ecosystem leading to observed balances between physiology and the marine environment.
