Srinivasan (RSMAS, U.S.A.)


1. Introducing Godae framework (1)

• Observations (< remote sensing satellites or in situ instruments)

• Analyses and forecasts (< modelling and assimilation systems)

• Data management and communication plan (to deliver regularly and seamlessly, reliable and comprehensive information on the state of the ocean)


1. Introducing Godae framework (2)

Other specificity of data and products :

• Targeted to Open Ocean global or regional sub-basins at higher resolution

• Focused on Ocean physics temperature, currents, sea level, salinity, wind/wave, sea ice

• Data are geo- and time-dependent (X, Y, Z, T) • Along an observational swath, or refer to a gridded area. • Characterised by spatial and temporal resolution of ocean phenomena:

large ocean circulation or eddy-resolving, daily or seasonal monitoring

• Special care on the time dimension.

• Various levels of products depending on quality & useFrom raw data (sensor type, level 0) to ocean summary information (ocean indicator, level 5).



2. The need for data & product serving (1)

depends on product level, operational status & user needs

1. “Privileged users” computer-to-computer link, no human intervention, high level availability and quality of service, routine delivery;

2. “Standard users” on request access to standard products (routinely produced) tools to search and access products;

3. “Public users”, ie. the general public for education and public outreach, a ‘front/demonstration’ window of operational oceanography;

4. “Specific users”, such as. research laboratories need specific products, which may not be available online human intervention for product delivery;

5. “Operations” involved in the system monitoring and supervision



User Requirements & Demonstration via Success Stories



• To understand how oceanographic centres operate each forecasting system SS1: A common knowledge and understanding of products

• To identify and converge on technologies required SS2:Data format and data inventory (for interoperability) SS3: How to find and discover products?

• To understand & evaluate products SS4 : How to better evaluate a product

(standalone or federated primary viewing services for data browse and quick evaluation)

SS5: Interactive viewing services (GIS based services or Google Earth for data qualification or science applications)

• To access and manipulate the data SS6: How to query and access a product ?

(full set or subset extraction capabilities, a chain of web services) SS7: Data manipulation and analysis

(for data qualification or science applications, web portals or desktop toolboxes)

• To keep track of downloads and usage of a product SS8: Monitoring and reporting

(to better meet the user needs and increase the use of data)

Conclusion (1)Achievements in 10 years

Measures of success or the instruments to monitor 10 years of cooperative work

• The GODAE implementation plan and the annual national reports

• Conferences and summer schools agenda

• lllustration through 8 success stories

Well defined products and services Improved design and effectiveness

of a global ocean observing system Enhanced coordination of activities at all levels

(observing forecasting, nesting) Growth of new multi-disciplinary integrated ocean applications

serving the ultimate goal of real user applications



Well defined products and services

• Distributed architecture with layered functionalities• Agreement upon formats and data distribution mechanisms

(the so-called GODAE standards)• Essential and generic network functions

to discover, visualise and access the data sets

Successful solutions across the GODAE community to create both standalone & integrated internet services

Clear demonstration of operational capabilities (including version tracking, system monitoring and robustness)



• Improved understanding of the oceans,

• Improved assessments of the predictability of ocean variability,

Minimised the cost and maximized productivity by drawing together information technology contributed by many partners

Enabled the assessment and operational qualification of ocean forecasting systems

Improved design and effectivenessof a global ocean observing system



• Official links established with large observation programmes like Argo, Sentinel 3 and others

• Agreement on qualification process, the metrics products (included in the so-called “GODAE standards”)

• Use of the Global Ocean Prediction System evidenced to support numerous coastal and regional modelling centres, delivering operational boundary conditions (see HYCOM US and Mercator, France)

• Usability/fitness of Godae products for the purposes of their users and system goals

Enhanced coordination of activities at all levels(observing forecasting, nesting)



Growth of new multi-disciplinary integrated ocean applicationsserving the ultimate goal of real user applications

Important applications already within the different national programmes

• marine safety in Canada to support the coast guard,

• fisheries in Australia to survey migration of the larvae of rock lobsters to maintain populations,

• maritime traffic in Japan to predict the Kuroshio large meander,

• marine pollution in France to monitor oil spill drift and to facilitate protective measures,

• water quality in United Kingdom to monitor the risk of problems from algae bloom, etc.
