Trichodesmium erythraeum is a globally significant nitrogen fixing marine cyanobacterium. Blooms of T. erythraeum can be seen in satellite images and it has been estimated that it is responsible for 42% of the global biological nitrogen fixation. Despite its ubiquitous nature, little is known about carbon and nitrogen fluxes both within the cells, between cells in a trichome and between cells and their environment. We have developed an advanced multiscale modeling approach which aims to accurately simulate these important interactions so that we can use the model as a predictive tool. We have validated predicted fluxes with both in situpopulation data as well as laboratory data.
