A Deep Dive into Macromolecular and Physiological Modeling
by Helen Hill for CBIOMES
At a two-day workshop held at MIT, January 28 and 29, a subset of the CBIOMES team gathered to share a focused dive into the detail of phytoplankton macromolecular and physiological modeling, coupled with an immersive exploration of how best to integrate such models into larger scale models of marine plankton distribution.

Towards a Better Model for the Microbe Membrane
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. Continue reading “Towards a Better Model for the Microbe Membrane”
Trends in Mediterranean Phytoplankton Phenology from Ocean-Color
by Helen Hill for CBIOMES
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. Continue reading “Trends in Mediterranean Phytoplankton Phenology from Ocean-Color”

A simple finite difference‐based approximation for biogeochemical tangent linear and adjoint models
by Helen Hill for CBIOMES
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.
