M. Belbeoch, Argo TC ASW#3 March 2009, Hangzhou

• 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) 2

• 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 3

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 ⇒ you are looking for something … just ask the TC ! 4

• Privileged contacts Scripps/Google • Include Argo layer in Google Ocean • Make Argo visible to general public • Make useful product for Argonauts 5 • Network Status, Stories, Ocean State

Argo Floats in AIC database 6128 Active Floats 3325 Argo Core ~ 2750 GDACs 3134 GTS 2931 "Grey Listed" 255 Polar Floats 87 Active Floats "Beached" 19 Argo Core Mission (60°N;60°S), no marginal seas: NOT YET ACHIEVED 8

• 1.5% are Beached or trapped in fishermen nets (15% in Marginal Seas) • Redeployed or • Secured • Shipped back / Recycled 9

Logistical challenge: Ship time Cooperation required (Argo, Argo/GOOS, new partners) 10

Southern Ocean still challenging. 11

Still room for improvement This will help to fill gaps … 12

Average Age: 672 Days Median Age: 540 days Deployment failure rate: 2.5 % 13

16 And anticipating where floats will soon stop to operate

• Argo groups are making substantial efforts to plan their deployments and optimize 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) 17

• #All Profiles 530576 • #DM Profiles 269976 • #Profiles eligible (obs. date > 1 year) 407472 • DM / DM eligible ratio 66% • 90% optimal quality (but not for all applications) 18

Transparency & Cooperation required ⇒ Argo Donor Programmes ⇒ 22 Training Workshops (West Africa, Pacific Islands) ⇒

TC • Oversee the Argo implementation • Apply lubricant in the Argo machinery People • Aims to • Structure • Monitor Information • Inform Systems • Assist • Promote Floats • Plan International • Harmonize • Serving Argo ... and the people who make it happen. 23

• Support & Feedback Challenges for the AIC: • Strengthen its infrastructure (cooperation within JCOMM) • Provide more assistance regarding logistics and deployment opportunities • Prepare a new generation of web services • Continue to help improving the GDACs (meta)data • Continue to foster participation by new countries via Donor Programmes • Improve tools to demonstrate how Argo meets its requirements • Continue to help sharing knowledge and harmonizing some practices 24
