A new study led by Samuel T. Wilson from the University of Hawai’i, co-authored with Darwin Project researchers John Casey, Stephanie Dutkiewicz, Mick Follows, Christopher Hill, and Oliver Jahn, uses the Darwin ecosystem model embedded within an MITgcm (~2 km) resolution regional physical model of the North Pacific Ocean to study how the input of silicic acid, iron, nitrate, and phosphate along the southeast coast of Hawai‘i impacts nearby phytoplankton productivity.

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. Continue reading When Phytoplankton Go Hungry
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
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
Look out for the Darwin team, sharing their work at this year’s Ocean Sciences conference taking place February 11-16 in Portland, Oregon. Continue reading Darwin Goes to Ocean Sciences 2018

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. Continue reading What you Can Do With a Really Rather Realistic Ocean Model

Microbes mediate the global marine cycles of elements, modulating atmospheric CO2 and helping to maintain the oxygen we all breath yet there is much about them scientists still don’t understand. Now, an award from the Simons Foundation will give researchers from the Darwin Project access to bigger, better computing resources to model these communities and probe how they work.
