Observations suggest diazotrophs like Crocosphaera and Trichodesmium pay for their ability to fix nitrogen with a very low growth rate, yet diatom-diazotroph associations or DDAs exhibit high growth rates. CBIOMES postdoctoral fellow Chris Follett and co-authors use a cell flux model to test the hypothesis that diatom-diazotroph associations or DDAs grow faster than unpaired diazotrophs because the diatoms in DDAs provide organic carbon to their diazotroph guests that boost their growth rate.

Committing to aggressive conservation efforts could rebuild ocean habitats and species populations in a few decades.

Study involving members of MIT-CBIOMES finds Earth’s oceans contain just the right amount of iron; adding more may not improve their ability to absorb carbon dioxide. Continue reading “Seeding Oceans With Iron May Not Impact Climate Change”
In a new paper, MIT-CBIOMES investigator Stephanie Dutkiewicz and collaborators use the Darwin ecosystem model to develop theories seeking to explain and predict phytoplankton biogeography.

Reporting by Helen Hill for CBIOMES
Senior Research Scientist Francois Ribalet and his team use underway flow cytometry to collect information about the abundance and size of small phytoplankton in the surface ocean. In a new paper published in the journal Scientific Data Ribalet, together with others from the UW-CBIOMES team and elsewhere, share their compilation of Northeast Pacific Ocean underway flow cytometry data collected over the past decade.
