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

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.

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.

Study from Follows Group finds large amounts of carbon dioxide, equivalent to yearly U.K. emissions, remain in surface waters. Continue reading
Ubiquitous marine organism has co-evolved with other microbes, promoting more complex ecosystems. Continue reading
Graduate Student Emily Zakem and advisor Mick Follows find bacteria can survive in marine environments that are almost completely starved of oxygen. Continue reading
Modeling the diverse world of phytoplankton opens up a predictive view of our own. MIT’s Spectrum Magazine spotlight’s the Darwin Project. Continue reading

The elemental composition of organic matter is remarkably constant throughout the world’s oceans, but phytoplankton are known to take up nutrients and carbon in quite variable ratios depending on light and nutrient conditions.
In a paper published online in the journal Global Biogeochemical Cycles last month, Darwin Project researchers David Talmy (MIT), Christopher Hill (MIT), Anna Hickman (Univ. of Southampton, England), and Mick Follows (MIT), in a collaboration with Adam Martiny (Univ. of California, Irvine), report on their work seeking to understand what ecosystem factors could cause the elemental composition of organic matter to remain stable and relatively constant (homeostatic), even when the phytoplankton can have quite variable composition.
