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.

Profiling Autonomous Floats
Argo 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.

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.

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.
