Simons Collaboration on Computational Biogeochemical Modeling of Marine Ecosystems
by John Casey for CBIOMES
CBIOMES Postdoctoral Fellow John Casey, has been working closely with MIT Group PI Mick Follows to combine quantitative proteomics, flux balance analysis of genome-scale metabolic models (GEMs), and molecular modeling in an attempt to estimate the parameters of a kinetic model based on transport fluxes, transporter abundances and structures, molecular diffusivity, and microscale fluid dynamics.

Changes in phytoplankton Chlorophyl (Chl) and phenology (study of the phases of the phytoplankton seasonal) are key to understanding many aspects of marine community structure and function. In new work, CBIOMES investigator Marie-Fanny Racault used remotely sensed ocean-color data to study patterns of variability and trends in phytoplankton Chl and phenology within the Mediterranean Sea.

CBIOMES investigators Paul Mattern and Chris Edwards present a technique that accurately approximates tangent linear and adjoint models for data assimilation applications based only on evaluations of the nonlinear model. The resulting approximation offers a simple way to create readily maintained tangent linear and adjoint model code as only major changes to the nonlinear model formulation necessitate modifications of the tangent linear or adjoint model code. Continue reading “A simple finite difference‐based approximation for biogeochemical tangent linear and adjoint models”

CBIOMES researchers in the Dalhousie Group looking at changes in phytoplankton biogeography in response to changing climate find mean phytoplankton niches closely tracked changes in mean temperature, while the mean salinity and mixed layer depth realized niches were consistently at the extreme range of available conditions at a study site near Sydney Australia.
