Scientific Objectives of Godae Ocean View

The GODAE OceanView Science Team (GOVST) was established in 2008, with the mission to define, monitor, and promote actions aimed at coordinating and integrating research associated with multi-scale and multidisciplinary ocean analysis and forecasting systems, thus enhancing the value of GODAE OceanView outputs for research and applications. Over the next decade, the science team will provide international coordination and leadership in:

• The consolidation and improvement of global and regional analysis and physical forecasting systems.

• The progressive development and scientific testing of the next generation of ocean analysis and forecasting systems, covering biogeochemical and ecosys tems as well as physical oceanography, and extending from the open ocean into the shelf sea and coastal waters.

• The exploitation of this capability in other applications (weather forecasting, seasonal and decadal prediction, climate change detection and its coastal impacts).

• The assessment of the contribution of the various components of the observing system and scientific guidance for improved design and implementation of the ocean observing system.

Members as representatives of national ocean forecasting systems of GODAE OceanView adhere to the same principles of free, open and timely exchange of data and products, sharing of scientific results and experience developing applications which were important factors in the success of GODAE. The societal benefits from these systems will only be realised through joint work with other teams of experts. Potential benefits include improvements in the day-to-day management of coastal waters, the management of marine ecosystems, weather prediction from hours to decades ahead, and the expected impacts of climate change on the oceans and coastal waters.

The GOVST develops linkages with other groups and reports on its progresses, achievements and recommendations. As GODAE prototype systems transition to operational systems, international collaboration on product standardization and interoperability between systems must be maintained and developed. The WMO/IOC Joint Technical Commission for Oceanography and Marine Meteorology (JCOMM) provides an appropriate intergovernmental mechanism for the coordinating role and has recently established an Expert Team on Operational Oceanographic Forecasting Systems (ET-OOFS) within its Services Program Area for this purpose. GODAE OceanView informally reports to JCOMM and has strong links with JCOMM ET-OOFS.

GODAE OceanView coordinates the development of new capabilities, in cooperation with other relevant international research programs, through a number of task teams. The initial list of GODAE OceanView Task Teams includes:

• Intercomparison and Validation Task Team:

The team pursues activities developed during GODAE. It coordinates and promotes the development of scientific validation and intercomparison of operational oceanography systems. Activities include the definition of metrics to assess the quality of analyses and forecasts (e.g. forecast skills) both for physical and biogeochemical parameters and the setting up of specific global and regional intercomparison experiments. Metrics related to specific applications are also defined. The team liaises with the JCOMM ET-OOFS team for operational implementation.

• Observing System Evaluation Task Team:

One of the aims of GODAE OceanView is to formulate more specific requirements for observations on the basis of improved understanding of data utility. The team is jointly formed by GODAE OceanView and the GOOS Ocean Observations Panel for Climate (OOPC). Through the task team, GODAE OceanView and OOPC partners get organized at the international level to provide consistent and scientifically justified responses to agencies and organizations in charge of sustaining the global and regional ocean observing systems used for ocean monitoring and forecasting at short-range, seasonal and decadal time-scales. This activity requires harmonized protocols for observation impact assessment (e.g. OSEs and OSSEs), tools for routine production of appropriate diagnostics using NWP-derived methods, common sets of metrics for intercomparison of results, and objective methodologies which can be used to provide recommendations to the appropriate agencies and organizations. In the longer term consideration will need to be given to an evaluation strategy for identifying observing system requirements for different, possibly user-specific, applications.

• Coastal Ocean and Shelf Seas Task Team:

This task team deals with scientific issues in support of multidisciplinary analysis and forecasting of the coastal transition zone and shelf/open ocean exchanges in relation with the larger-scale efforts. The specific objectives include: (1) discuss and promote the uses of GODAE OceanView products and results for coastal ocean forecasting systems and for coastal applications in a wider community; (2) discuss and foster integration of the varied routine sources of information in coastal ocean forecasting systems: large-scale forecasts, satellite observations, coastal observatories, etc.; discuss and support the development of coastal observing systems in terms of science and technology; (3) discuss the key physical and biogeochemical processes which have the greatest impact on modeling and forecasting quality and their utility for applications; this includes validation and forecast verification; (4) discuss and promote state-of-the-art methodology such as two-way coupling, unstructured-grid modeling, downscaling, data assimilation and array design.

• Marine Ecosystem Monitoring and Prediction Task Team:

The integration of new models and assimilation components for ocean biogeo-chemistry and marine ecosystem monitoring and prediction will be required to bridge the gap between the current status and new applications in areas such as fisheries management, marine pollution and carbon cycle monitoring. The Task Team has been set up with the goal to define, promote and coordinate actions between developers of operational systems and ecosystem modelling experts, in tight connection with IMBER. The objectives of the task team are (1) to design appropriate ecosystem modelling and assimilation strategies that will be compatible with the functionalities of operational systems; (2) to develop numerical experiments aimed at improving, assessing and demonstrating the value of operational products for marine ecosystem monitoring and prediction; (3) to expand the concept of the "GODAE metrics" to biogeochemical variables and to coordinate intercomparison exercises across international groups to assess implementation progress and performances; (4) to identify the essential sets of physical and biogeochemical observations required to constrain the coupled models and to formulate relevant recommendations to further develop the global ocean observing system; (5) to promote and organise educational activities (summer schools, training workshops, etc.) aimed at sharing experience between young scientists, operational oceanographers and marine ecosystem experts. In addition to the link with IMBER, the task team articulates its activities with other relevant international programs such as GEOTRACES and SOLAS.
