#O07 Ocean/Ice BGC in ACME

Abstract

In preparation for the ACME BGC series of coupled simulations, we have implemented models of biogeochemical and ecosystem dynamics with the MPAS framework within ACME.  The ocean module is a port of the CESM package developed by Moore, etal (2004), with the addition of LANL-developed dynamic dimethyl sulfide (DMS) and explicit decomposition of dissolved organic carbon into specific macromolecular classes.  The sea ice BGC is a new vertically resolved collection of reactions designed by Jeffery, Elliott, and Wang to be complimentary to the ocean formulation.  As a result, we are able to pass constituents between models for studying truly coupled interactions.  Since the ocean BGC is based on the CESM formulation, comparisons of ACME/MPAS results with CESM/POP and with data products can provide a baseline validation.
