Regional Ecosystem Modeling Testbed Project

Second Regional Ecosystem Modeling Testbed Workshop

The second Regional Ecosystem Modeling Testbed Project Workshop was held 21 - 23 March, 2005 at the Center for Coastal Physical Oceanography, Old Dominion University. Fourteen scientists from nine different institutions attended this very successful meeting, including:

                            Larry Anderson (Woods Hole Oceanographic Institution) 
                            Robert Armstrong (MSRC, Stony Brook) 
                            James Christian (CCCMA, Victoria)
                            John Dunne (NOAA/GFDL) 
                            Jeff Dusenberry (Woods Hole Oceanographic Institution)
                            Marjorie Friedrichs (Old Dominion University)
                            Masahiko Fujii (University of Maine)
                            Eileen Hofmann (Old Dominion University)
                            Raleigh Hood (HPL, University of Maryland) 
                            John Kindle (NRL, Stennis Space Center)
                            John Klinck (Old Dominion University)
                            Markus Schartau (MSRC, Stony Brook)
                            Yvette Spitz (Oregon State University) 
                            Jerry Wiggert (Old Dominion University) 

The goals of the workshop were (1) to investigate why certain models fit certain data better than others, in the Equatorial Pacific, in the Arabian Sea, and in both sites simultaneously, (2) to discuss methodological issues concerning the implementation of the testbed framework, (3) to determine how best to assess the performance of the models, (4) to outline the upcoming EGU/AMEMR presentations and the JMS manuscript and (5) to discuss the future of the Testbed Project.

Results stemming from this workshop will be presented at the European Geosciences Union (EGU) meeting in Vienna (April 25-29 2005), and at the Advances in Marine Ecosystem Modelling research symposium in Plymouth (27-29 June 2005).  A manuscript will also be submitted to the AMEMR special volume of the Journal of Marine Systems emanating from this symposium. 

Prior to the workshop, participants were provided with the testbed framework, which included Fortran routines for processes including advection, diffusion, mixing, sinking, and attenuation. In addition, standard forcing time series (mixed layer depth, vertical and horizontal advection, solar radiation), initial conditions, and biogeochemical validation data (chlorophyll-a, zooplankton biomass, nitrate, sediment trap, primary production) were provided. Each participant was responsible for creating the adjoint of their specific ecosystem model subroutine using the TAMC, plugging these subroutines into the testbed framework, and providing time series of ecosystem model output (plankton, nutrients, etc...) Friedrichs synthesized these results and presented the model comparisons for discussion at the workshop.
