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.

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.

In their new competition theory paper, appearing in the 2014 issue of Biogeosciences, Dutkiewicz et al examine the sensitivity of the biogeography of nitrogen fixers to a warming climate and increased aeolian iron deposition in the context of a global earth system model. Continue reading
The nitrogen cycle is fundamental to Earth’s biogeochemistry. Yet major quantitative uncertainties remain, particularly regarding the global oceanic nitrogen fixation rate. Continue reading
