  1. The Argo Project21st Century in-situ Ocean Observing Systemto update …

  2. What is Argo ? • A new way to collect data from the ocean using robot floats • « Take the pulse » of the Ocean’s upper layer in real-time • Complement to satellite and other in-situ observing systems • Access to data is free and unrestricted • Target- a 3° x 3° global array ( ~3000 floats) • Benefits: • Improve Ocean and Climate forecasting • Understand ocean-atmosphere interactions • Predict seasonal to decadal climate variability • Wide range of applications for high-quality global ocean analyses is anticipated

  3. Standard Float Cycle • Drifting Depth: 1000 m • Profiling Depth: 2000 m • 10 Days Cycles

  4. Float Technology: complex & “revolutionary” • Float designs APEX, PROVOR, SOLO, NINJA, COPEX, NEMO • 150-200 cycles (4-5 years lifetime) • T/S Profiles down to 2000 dbars • CTD stable: 1 dbar, 0.001 °C, 0.01 Psu • Air/Ship Deployments • Argos Communications • Optical, Acoustic, Dissolved Oxygen sensors … • Iridium communications • Next generation profiling floats (IFREMER, JAMSTEC) • Technological Challenge

  5. Organization National programmes contributing to : • GODAE/CLIVAR pilot-project • A major contribution to GOOS/GCOS • Endorsed by WMO and IOC • Argo Steering Team Argo Data Management Team • Argo Project Office: • Director (J. Gould, CSIRO, Hobart, Australia) • Coordinator (M.Belbeoch, Argo Information Centre - JCOMMOPS, Toulouse, France)

  6. Data Management • 2 channels of real time distribution: • GTS of WMO - mostly to operational users • Internet from 2 Global Data Centres (GDACs) - available to all • National Data Centres feed the GTS and 2 GDACs : Coriolis Server (IFREMER, France) GODAE Server (FNMOC, USA) • Standard Real-Time QC applied • Delayed-Mode QC being finalized (data available from GDACs after delay of 6-12 months) • Regional Centres being established • Long Term Archival Centre established @ NODC, USA

  7. Argo => Operational Data Distribution - 9 established DACs feed GDACs - 98% of data delivered in real time to GTS and GDACs (84% of these within 24h - source MEDS)

  10. Argo Status

  11. All Argo deployment locations (2004 red) • Target deployment rate reached in 2004 (~800/year) • Argo pilot-project feasibility demonstrated • Southern Ocean still a challenge for Argo …

  12. Young network (50% < 1year) - early floats had short life

  13. Fleet of US, French, German and Japanese manufactured floats

  14. Argo Profiling • Depths (Deepest profiles at high latitude)

  15. Argo => International Project

  16. Argo is supported by: ARGENTINA-AUSTRALIA- CANADA- CHILE- CHINA- COOK ISLANDS- COSTA RICA- DENMARK- EUROPEAN UNION- FIJI- FRANCE- GERMANY- ICELAND- INDIA- INDONESIA- IRELAND- JAPAN- KIRIBATI- KOREA (REPUBLIC OF)- MARSHALL ISLANDS- MAURITIUS- MEXICO- MICRONESIA, FEDERATED STATES OF- MOZAMBIQUE- NETHERLANDS- NEW CALEDONIA- NEW ZEALAND- NIUE- NORWAY- PAPUA NEW GUINEA- RUSSIAN FEDERATION- SAMOA- SOLOMON ISLANDS- SOUTH AFRICA- SPAIN- TOKELAU- TONGA- TUVALU- UNITED KINGDOM- UNITED STATES- VANUATU- EEZ access to complete the array

  17. Float Retrieval Procedure • 1% expected to be retrieved • 50% of the fleet have labels • Target is to label all • Countries responsible for retrieval of floats when found

  18. Argo Initiatives in South America • Float Donations: to Chile, Costa Rica and Mexicovalue$15,000 /unit + Communications :- Shipping paid by recipient - Deployment location choosen using regional expertise but adhering to Argo standards • Invitation to support Argo sent by intergovernmental channels (IOC) • Visit of TC (seminars, training on float technology) • Contacts needed for the Atlantic side • Goal: Finalize these initiatives at a South American Argo Workshop (Contacts needed)

  21. Examples of Argo data use With Argo Non Argo UK Met Office assimilating salinity in global model Forecasting currents around Australia David Griffin , Bluelink project, Australia Environmental Impact assessment Gulf of Alaska (H Freeland Canada) Monitoring monsoon impacts (Ravichandran)

  22. Conclusion: • Almost 1700 operational floats • Free data distribution and sharing • Target deployment rate reached in 2004: 838 floats • Network is young: (50% fleet < 1 year old) • Deployment failure rate decreased from 8.6% (2001) to 1.9% (2004) • 90% of the fleet is profiling deeper than 1000m • Argo is truly global and international (19 countries, 50 regional initiatives, more to come) Argo is doing well !

  23. Challenge: • Sustain the funding long enough to complete the global array … • … and demonstrate its value. => Continuous interactions between Research & Operational communities
