Established in 2001 (Toulouse/France)
Funded via national voluntary contributions (Australia, Canada, China,

France, Germany, India, Korea, USA, UK)

International rules (Exclusive Economic Zones issues)
Technical coordination of the Argo programme
Guidelines by the Argo Steering Team
Close links with national/regional Argo initiatives
Close cooperation with international organizations (IOC/UNESCO &

WMO)

AIC/JCOMMOPS (Argo, DBCP, SOT, OceanSITES)

assist in the planning, implementation and operations of Argo
monitor and evaluate the performance of the network
encourage cooperation between communities and member states
provide technical assistance and user worldwide support
act as a clearing house and focal point on all programmes aspects
encourage data sharing
assist in data distribution on Internet and GTS
relay users feedback on data quality to platforms operators
The AIC is not a data centre, rather, it:

– gathers, QCs, and distributes essential metadata – help GDACs to serve better data – guides users to data centers

SLIDE 4

Information System

Official Argo float database

– Updated with new floats every month – Essential metadata are checked by TC for each float (6000+ so far!) – Links to all GDACs, DACs, RDACs products

Deployment Planning tools
Realtime monitoring tools (global, national, float groups, …)
Contacts, documents, news, weblinks, medias, ...
Provide visibility for all argo related activities
Users Support/Feedback Centre: support@argo.net

2008 was a good year for Argo, with increased contributions from Australia, China, France and Germany. Southern Ocean still challenging.

Argo groups are making substantial efforts to plan their deployments and
ptimize the array coverage.
Implementing an empty ocean … maintaining a global array.

To be noted the strong increase of China contribution to Argo (~40 floats in 2009)
