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

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

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 2006. ~20pers 2nd, Palma de Mallorca, Spain, Oct 2007. ~40pers 3rd, La Spezia, Italy, Oct 2008. ~90pers 4th, Larnaca, Cyprus, Nov 2009. ~80pers 5th, Telde, Gran Canaria, Spain, Mar 2011 ~130pers Showcase website http://www.ego-network.org 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

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 “ES0904 - 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) http://www.ego-cost.eu http://www.groom-fp7.eu

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

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.

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

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

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

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) ?

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

EGO: desired outcomes from participation in JCOMM / OCG?

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
