Kīlauea Lava Fuels Phytoplankton Bloom off Hawaiʻi Island
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.

Fourth Annual Traits Workshop
Reporting by Helen Hill for the MIT Darwin Project
The fourth Workshop on Trait-Based Approaches to Ocean Life, held August 18-21, 2019 at Chicheley Hall in Buckinghamshire in the UK was a wonderful opportunity for Darwin Group members to catch up with former colleagues while sharing current directions in marine ecology viewed through a traits lens.
The Color of Climate Change
The Color of Climate Change by Eva Frederick, Karina Hinojosa, Devi Lockwood, Gina Vitale – MIT Graduate Program in Science Writing
Darwin researchers Stephanie Dutkiewicz, Jonathan Lauderdale, and Oliver Jahn talk about their work modeling the ocean to explore how ocean color may change under climate change.
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
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
Darwin Goes to Ocean Sciences 2018
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
A More Diverse Role for Diatoms
Helen Hill | Darwin Project
A review article involving Stephanie Dutkiewicz and Oliver Jahn suggests the diatoms have more diverse roles in carbon cycling than previously understood. 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.
