Activities of the South Atlantic Argo Regional Center (SA ARC)
Silvia Garzoli, Bob Molinari, Claudia Schmid (NOAA/AOML) , Huiqin Yang (CIMAS/UM)
M/V Atlantic Action (Cyprus) Tema (Ghana) to Cape Town
Agreement with Prof. A. K. Armah, from the University of Ghana. They will facilitate the transfer of one of our ship riders from the airport to the port and the loading of the equipment.

Donation Program
To fill up gaps in the South Atlantic using ships from Brazil and Argentina.
with the University of Cape Town, South Africa to deploy floats from the RV Agulhas.
With the Argentine SHN to deploy floats from the RV ARA Puerto Deseado
Collaboration programs(Through SA ARC)
AOML to centralize and post the information for the whole Atlantic.
•Donation program•Agreements with Argentina, Brazil, South Africa, Ghana.
Logistics and floats deployments
Comparison with nearby profiles (in space and time)
Comparison with climatology
Report potential problems to float PI who will correct them if possible.
Identify problems with the data quality

Depth: 400 m, Years: 1997-2004
Comparison of Argo 400-m T with climatology (not shown) and buddies
• determine the robustness of the climatology
• evaluate the performance of the floats

Comparison of Argo 400-m S with climatology (not shown) and buddies
Summary
• T/S deviates from climatology in high latitude South Atlantic (most likely problems with climatology)
• S deviates from climatology in western tropical Atlantic
• Buddy comparison help identify problematic floats
Training and Outreach
Ghana Workshop: Welcome!
Next steps?
• Coordinate the activities needed to develop the Reference Data Sets. We propose to add an ARC component to the next Data Management or delayed QC meetings.
• May 2007; South Atlantic International MOC meeting in Argentina. We propose to add a section on SA ARC to evaluate the progress and to use the opportunity to expand our deployment opportunities in the region.

SST Anomalies: View 5-day (pentad) SST anomaly maps for the Caribbean Region. Spatial resolution is 9.28 km.
Atlantic SST maps: Display and retrieve daily and pentad Sea Surface Temperature maps for the Atlantic Ocean. These maps are created using data from the POES satellites.Near Real Time Wind Data: Display and retrieve surface wind data from a variety of sensors (QuikSCAT, SSMI, TMI, ERS-2, TOPEX, Jason-1, GFO and Drifters).
Upper Ocean Heat Content: Upper ocean thermal structure derived from the Sea Surface Height and Sea Surface Temperature fields. Updated daily.
