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

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.

Plankton can save the ocean. But who will save the plankton?
Read this post by Lauren Hinkel via Oceans@MIT
When it comes to climate change and the oceans, MIT Principal Research Scientist Stephanie Dutkiewicz weighs in on why it’s not just warming oceans we need to worry about. Plankton — that are crucial for carbon sequestration and oxygen production — have been discovered behaving strangely, but they may point the way to better geoengineering and understanding of trends in marine populations and ecology.
Dutkiewicz’s research examines how the physics and chemistry of the ocean determines phytoplankton biogeography, and how in turn those organisms affect their environment.

Ocean acidification may cause dramatic changes to phytoplankton
Study led by principal research scientist Stephanie Dutkiewicz finds many species may die out and others may migrate significantly as ocean acidification intensifies. Continue reading
