GODAE Achievements GODAE Achievements and Successes (1998-2008)and Successes (1998-2008)

Implementation of observing and data processing systems• Argo and GHRSST (pilot projects), altimetry, in-situ

Implementation of global modelling & data assim. capabilities• High resolution and climate

Implementation of data/product serving capabilities• Inter-comparison / validation, metric and standardisation

Demonstration of feasibility and utility• Mesoscale nowcasting and forecasting, ocean climate research, marine pollution and safety, weather forecasting, marine resources, etc.

Scientific advances• Modelling, data assimilation, scientific validation

The New Challenges (1)The New Challenges (1)Face emerging new societal needs

• Understand/monitor/forecast the earth system from days to decades– Improve atmospheric forecast where the ocean impacts it (cyclones,

monsoons, …)– Application of ocean prediction techniques to improve climate and

decadal prediction including the ocean contribution

• Where (most) people live– Improve near-shore/coastal waters real-time prediction (coupling to

and/or downscaling from the offshore/deep ocean; physics, biogeochemistry)

– Understand the impact of climate change in coastal regions (downscaling)

• For the sustained exploitation of the seas– Develop ecosystem-based management of marine living resources

Support environmental policies through environmental monitoring


The New Challenges (2)The New Challenges (2)Improve and extend our capacities

• Research and development in ocean modeling, data assimilation

• Coupling with other components of the earth system

• Cooperation with international research programs (e.g. WCRP, IGBP, SCOR)

Improve accuracy of the environmental information and products


The New Challenges (3)The New Challenges (3)Better observe the ocean

• Help the international organizations in charge of the development of the ocean observing systems:

– For the transition to sustained operations of the global in situ and space observing system

• better use of existing systems, such as ARGO, Jason, …

– For the design/assessment of new observing systems• new observable (e.g. bio, …), new focus (e.g. coastal, …)

– For the optimization of the resources• measure the relative impact, assess the utility, etc… through

OSE/OSSE

Evaluate benefit and optimize use of the GOOS

GODAE OceanView Task TeamsGODAE OceanView Task Teams

• TASK TEAMS address specific topics of particular importance to GODAE

OceanView require collaboration with international research programs or

other groups (e.g. coastal community):– Inter-comparison and Validation (Martin & Hernandez)

– Observing System Evaluation (Oke & Larnicol)

– Coastal Ocean and Shelf Seas (DeMey & Kourafalou)

– Marine Ecosystem Analysis and Prediction (Barciela & Brasseur)

– Short- to Medium-Range Coupled Prediction (Brassington)
