1 EGO: Everyone’s Gliding Observatories
Pierre Testor LOCEAN, CNRS, Paris, France The Economist, 2012/06/09 OCG-5, September 2013

2 Scientific/ operational community, users
EGO: gliders capabilities global scale Data Centers Scientific/ operational community, users Regional scale Scale interactions seasonal Land Station mesoscale submesoscale 1km ~2-5km Processes Maneuverable ; U ~ 25km/day ; a ‘dive’ in ~0.5-5h (1-2 ‘vertical’ profiles) Physical and biogeochemical sensors (ECV/EOV: T, S, O2, ADCP, fluo Chl, fluo CDOM, optical backscatters, nitrates, hydrophones,… ) + average currents over the dives Versatile and reusable high spatial and temporal resolution profiles during (~2-4 < 11) months real time data for “operational models” and “process studies” (global, regional and coastal) Emergency/environmental response OCG5 - September 2013

3 EGO: a glider community (sci & tech)
EU, USA, Canada, Australia, Mexico, South Africa, Peru, Chile,… (academics+manufacturers) EGO meetings and Glider Schools 1st, Paris, France, Oct ~20pers 2nd, Palma de Mallorca, Spain, Oct ~40pers 3rd, La Spezia, Italy, Oct ~90pers 4th, Larnaca, Cyprus, Nov ~80pers 5th, Telde, Gran Canaria, Spain, Mar 2011 ~130pers Showcase website International collab. fleet experiments OceanObs’09 White Paper (Testor and 44 co-authors, 2010). Gliders can be used in combination with the other components of the GOOS (Satellites, OceanSites, Argo,…) enhance the spatio-temporal sampling of the GOOS (in-situ) where required. (reduce uncertainties due to small scale processes ; coverage in coastal/marginal/regional seas, water formation sites, biogeochemical provinces, western and eastern boundary regions, straits) OCG5 - September 2013

5 EGO: requirements-setting process/es
OceanObs’09 recommendations: the formation of the global glider system; the adoption of standards and a “Argo” like data system for gliders; the target of ~20 standard lines in the next 5 years and then, more; the setup of a network of shared resources and expertise; to distinguish between climate and process and NWP objectives; to establish the adoption of a common and accessible portal for glider data. Development in the framework of 3 main research communities: USA: IOOS - NGN Australia: IMOS - ANFOG EU: COST Action “ES EGO” (coordination/wide-open: include Australia, South Africa, Israel, Mexico,… Canada, Peru, Chile,…) FP7 Research Infrastructure design study “GROOM” Gliders for Research, Ocean Observation and Management (WP2 Integration into the GOOS)

6 EGO: issues and challenges
Two-way communication system (pilots!) Expertise required (gliderports = communication and computer resources, workshops for maintenance and development, pools of gliders, sea-access) Numerous operators and distributed facilities Map of “main” gliderports

7 EGO: issues and challenges
best practices for gliders ! the formation of the global glider system; the adoption of standards and a “Argo” like data system for gliders; the setup of a network of shared resources and expertise; to establish the adoption of a common and accessible portal for glider data.

9 All glider deployments since 2005
EGO: issues and challenges All glider deployments since 2005 (+ deployments in the Artic/Antarctic, SE/SW Pacific, Polynesia, Indian ocean,…) Process studies AND long-term observations Monitoring the glider network activity is based on the operators good will. Maybe ~500,000 profiles since 2005. A lot of data sent to data centers but… USA ~ 12,000 km altitude EU AU

10 ! EGO: issues and challenges All platforms
… the data flow is interrupted somewhere! data during 3 months (April-June 2013) from no glider data at all during the last month… ! Gliders Last month glider data at Coriolis > 11 gliders in the water OCG5 - September 2013

11 EGO: issues and challenges
Just in-between “pilot” and “mature” networks. The integration of gliders (as platforms) is nearly done - just the last steps glider officer/coordinator position to open ? Support for deployments/recoveries (coordination for ships opportunities,…) monitoring the network downstream the glider operators/communities voice/advocacy in international panels ½ position ? To be shared with regional/coastal coordination purposes ? Maritime law/traffic issues No global glider-specific program yet (‘only’ a superposition of projects, some/few of which are long term observations) - although straightforward for marginal seas (EEZs)  versatility = a strength and a weakness Sustainability of the network ? Consolidate the international EGO scientific network after the end of the COST Action ES0904 “EGO” (July 2014) Consolidate the network of “gliderports” for a better range OCG5 - September 2013

12 EGO: strategy for evolution of observing system/sensors
Network evolution fill the gaps! Common data format/standards Capacity building: develop the network (coastal/regional and global scales) GOOS/GRA/ROOS endorsement to leverage funds and foster collaboration with the other components Discussions on a global and glider-specific program (trade-off regional/global ?)  scale arguments and OSSEs Hardware evolution : New sensors (also relevant for “Bio-Argo”, marine meteorology) Better endurance (1 year ?) Deep (6km) gliders (cross-basin sections  “WOCE 2.0” ) Wavegliders (ASVs) ?

13 EGO: integration across networks
Data management (RT and DM) and technical coordination for physical and biogeochemical data/sensors (Argo/OceanSites models) Two-way communications paradigm (is EGO a model?) - messengers How far ? Links/complementarities with other components (solve coverage issues ; cross-calibration,…) - “a GOOS glider project” and/or “the glider sides of GOOS projects” ? Satellites Variability around moorings Between Argo floats (300km, 10 days) Around R/Vs … (Testor et al, 2010 CWP) EGO/GROOM ‘artistic’ view

14 EGO: desired outcomes from participation in JCOMM / OCG?
Weather & Climate UNFCCC/IPCC WCRP Regional Regional seas MSFD CCAMLR Fisheries FAO Ecosystem services/biology CBD CSD WSSD Assessments Global Marine (UN) TWAP (GEF) Real-time services Emergency support Ocean forecasting Issues Issues Requirements Requirements Essential Ocean Variables Expanded EOVs Argo Gliders in the loop! SOOP VOS Expanded observing systems and networks Issues impact Data products Data Assembly Satellite IMOS Endorsement, visibility and more outreach/awareness  sustainability and capacity building Help to solve the maritime law/traffic issues Better use of glider data (e.g. in-situ/satellite comparisons, models,…) Better coordination with the other in-situ components Snowball effect for (future) glider operators Definition of a global glider program ; consensus on main scientific objectives IOOS
