2. IGOS Ocean Theme IGOS Partners launched the Ocean Theme as a pathfinder for integration and implementation of a common observing strategy Main Objective –Describe need for ocean observations (motivation) Continuity challenge - operational Knowledge challenge - research and development –Describe gaps and overlaps (enable implementation decisions) –Promote integration of space-based and in situ observations Original Ocean Theme Plan - January 2001 Revision of Ocean Theme - Target 2004

3. IGOS Ocean Theme The Ocean Theme completes the design of GOOS by making explicit the space based observations required by GOOS.

5. Profiling Autonomous Floats These are oceanic analogues to radiosondes used in operational meteorology. Parked at 2000 m of depth, they ascend to the surface collecting a high precision profile of the density structure of the upper layers of the ocean. Argo floats:

10. IGOS Ocean Theme Current Status and Commitments –Continuity Goal Ocean Surface Topography - Launch of Jason-1, plan for Jason-2, involvement of NOAA and EUMETSAT (Kyoto). Ocean Vector Winds - Launch of Seawinds, plan for follow- on and series of ASCAT on METOP. Incorporation of scatterometer data in operational forecast systems. Ocean Color - SeaWiFS extended, 2nd MODIS on orbit, multiple missions planned and on orbit - challenge for integration of data sets. Sea Surface Temperature - continues with development of improved data sets from research

11. IGOS Ocean Theme Current Status and Commitments –Salinity - Missions in planning (SMOS, Aquarius). Active science teams for both missions. –Bottom Pressure - GRACE launched and providing initial data set –Use of Reflections of Global Positioning Systems - International working group meeting annually. Scientific applications and technological capability continue development.

19. IGOS Ocean Theme Future developments –Review and revision of Ocean Theme: 2004 –GOOS: more emphasis on products and services to energize transition of key satellite measurements from a research to an operational basis. –Use the support provided by JCOMM and the results of GOOS Review

20. The Ocean Theme Review 1. Re-organization of Ocean Theme Report First level by environmental parameters. Second level by organization Continuity challenges Knowledge challeges Implementation issues 2. Boost in-situ systems content: level of detail 3. Expand by including sections on interfaces with; Coastal theme Carbon theme Water cycle

21. The Ocean Theme in 6 Points 4.Elaborate and recognize relationship with solid earth systems and geodesy. 5. Develop the issue of human capital and capacity building to assure success in the development of observing system. 6. More examples and successes in data/products services. Success of ocean data systems should be highlighted. Feedbacks between observations and products. 7. Recognize maturation of implementation mechanisms. 8. Incorporate new and better socio-economic justifications.
