Abstract:

Macromolecules are large, complex molecules essential to life, including proteins, carbohydrates, lipids, pigments, and nucleic acids. Given the functional differences across macromolecules, resolving these molecules is key toward reflecting plankton physiology in ocean simulations, which are closely tied with global ecology and biogeochemistry. Here, I will introduce the Cell Flux Model of Phytoplankton (CFM-Phyto), which resolves intracellular allocation of macromolecules, and demonstrate how I incorporated it into the global ocean simulation. The strength of the model lies in the multi-level validation from the laboratory scale to the regional and global ocean scale. The results demonstrate a close link between macromolecular allocation and elemental stoichiometry, both of which are governed by physiological acclimation and ecological selection in phytoplankton, thereby bridging cellular phenomena to global-scale organic chemistry
