MEAP-TT activites


MEAP-TT thumb

The focus of this MEAP-TT is to develop the underpinning science and tools which will eventually enable full integration of biogeochemistry and, ultimately, ecosystems in existing physical operational systems. Its mission is to contribute to the improvement of the biogeochemical observing systems, assimilation and modelling of Essential Biogeochemical Variables (EBV) and bridging the gap with end-users. This is an area of growing interest to GOV and its supporters.

The integration of new models and assimilation components for ocean biogeochemistry and marine ecosystem monitoring & prediction is required to bridge the gap between the current status of the GOV capabilities and new applications in areas such as fisheries management, marine pollution and carbon cycle monitoring. Although in the foreseeable future the focus of the MEAP-TT will be on biogeochemistry and the lower trophic level it is anticipated that scientific advances in these areas will foster closer collaboration with ecosystem research in the medium to long term.

Following the outcome of a first IMBER-GODAE working group established in 2007, the Marine Ecosystem Analysis and Prediction Task Team (MEAP-TT) has been established with the goal to define, promote and coordinate actions between developers of operational systems and experts in biogeochemical, respectively ecosystem modeling, in tight connection with international organisatiions, e.g. IMBER.

Although alternatives to the current task team have been considered in the form of incorporating MEAP-related activities into the work of other GOV task teams (all teams covering not just physical systems but also biogeochemistry) it was found that such an arrangement would not adequately support the biogeochemistry/ecosystem-related work within GOV better than the existing arrangement.

The objectives of this Task Team are to

  • Demonstration of improved biological/biogeochemical model skill through data assimilation
  • Promote the exploitation of biogeochemical products in support of management and monitoring of ecosystems, fisheries and carbon;
  • Demonstrate usefulness of green OO products to end-users through identification of metrics for system evaluation in view of transfer to operational services
  • Assessment of dependence of model skill on biological/biogeochemical model complexity with emphasis on model portability and predictive skill
  • Contribute to the design of Essential Biogeochemical Variables observing systems
  • Research and develop downscaling methods from global to regional systems for biological/ biogeochemical model applications

These objectives will be further developed in synergy with other GOV TTs and in dialogue with the group of Patrons. This approach will enable to better identify the added value and to quantify the benefits of this particular task team. One of the issues in determining the objectives for the group is that the interests of the Patrons extend from biogeochemistry to ecosystems. Interests are further divided between the shelf seas and the open ocean. The open ocean focus is closer to the original core of GOV, but many immediate applications lie within the shelf seas and coastal regions. The choice to focus the MEAP-TT solely on the open ocean has been re-evaluated and extended to also include the shelf-sea areas.

The measures of effectiveness as expressed in terms of mission needs of the Patrons are:

  • MEAP-TT seen as a source of expertise and advice for decisions to be made by Patrons, e.g. about prioritizations of and investments in the biogeochemical/ecological ocean and coastal observing system with information derived from Observing System Simulation Experiments (OSSEs);
  • the integration of new satellite-based biogeochemical data (either as radiation data or in derived form, e.g. chlorophyll-a) in data assimilating coupled bio-physical models.
  • the determination and implementation of metrics for evaluating operational biogeochemical predictions

The activities of the MEAP-TT will be facilitated by annual workshops. Additionally, future work of this task team will engage the sponsors and encourage collaboration through symposia, workshops, and other similar community efforts.
