Reduced Order Biogeochemical Flux Model For Use In High-Resolution Multi-Scale Biophysical Simulations
In order to address this need, we have developed the reduced-order, 17 state variable Biogeochemical Flux Model (BFM17), which has been derived from the full BFM for the purpose of coupling with fully three-dimensional, non-hydrostatic large eddy simulation (LES) models. BFM17 is complex enough to capture behavior of open ocean biogeochemical systems, but reduced enough to integrate within high resolution LES simulations without unreasonable growth in computation time and data storage. When coupled with the 1D Princeton Ocean Model, BFM17 shows good agreement between predicted monthly-averaged results and Bermuda testbed area field data (including the Bermuda-Atlantic Time Series and Bermuda Testbed Mooring). In this talk, we discuss the use of BFM17 within a LES model of submesoscale circulations and outline how this will further our understanding of turbulent biophysical interactions in the upper ocean.
