There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Paul MatternWhen Marine Ecosystem Models Meet Observations
Marine ecosystem models are important tools for predicting the biochemical state of the ocean. Models are often used to fill gaps in observational data, yet unconstrained model simulations can quickly diverge from realistic results. As a result, including data assimilation into modeling efforts is an essential step toward improving model predictions. A particular challenge in incorporating data into ecosystem modeling is the large number of biogeochemical tracers in models (e.g. nutrients, plankton), and the lack of available observations.
In this talk, we present data assimilation in a regional model of the US West Coast using the Regional Ocean Modeling System (ROMS) and show applications of biogeochemical parameter estimation. We highlight how increased model complexity in more advanced biogeochemical models can lead to more realistic model output while complicating data assimilation.
