Gradients 5 cruise in the tropical Pacific

Friday, 03 March 2023

Laura Bretherton, Niall McGinty, and Kevan Merrow participated in the Simons Foundation-funded Gradients 5 cruise as part of the SCOPE research program.

During 28 days at sea, Laura, Niall and Kevan collected dozens of samples of phytoplankton and zooplankton communities for analysis back in the lab. When all the processing is done, we will have much better knowledge of elemental (C, N, P) and macromolecular content and ratios for these communties across a gradient that spans …

Our research lab moved to Dalhousie in 2018. After much planning, packing, and unpacking we opened the new wet lab on November 29, 2018.

To mark this milestone, our lab manager, Ruby Hu assembled a short video documenting the process: youtube video

Bayesian modeling workshop

Monday, 01 January 2020

The first Simons CBIOMES workshop on Bayesian methods in plankton modeling was held on January 8-10, 2020, at the Samberg Conference Center on th MIT campus. Twenty eight participants represented all 10 of the CBIOMES Investigator labs. The workshop combined introductory lectures, instruction in use of the “Stan” software toolkit, and focused ‘hackathon’ time where participants tackled targeted problems from their research using Bayesian statistical methodology. …
