–Spatial and/or temporal High Frequency sampling
–(near)real time data access
A long term coherent network to analyze and to understand:
–Evolution and varaibility of currents and hydrological structure
–Water and mass exchanges between land and ocean
–Nature and and availability changes of nutrients
–Structure evolution of trophic chain
(index of the plancton biodiversity)
considering intermittent and extreme events to effects of climate change in coastal regions.
Components of the network
Three main observation systems:
- Fixes platforms,
- Opportunity measurements,
- Coastal profilers.
(1) Plateformes fixes
o MAREL systems (MAREL Molit, MesuRho, MAREL Carnot): multi-instrumented "open" buoys,
Data access (Molit and Carnot)
Description and access to Molit data: DOI
Description and access to Carnot data: DOI
Data access (Mesurho)
o SMATCH (NKE) buoys of the island network: autonomous T/S probes (could be extended to multiparameter probes),
o SMATCH for shellfish farming (RESCO network): autonomous T/S probes in shellfish farming area.
Three added systems in the network:
– SMILE buoy (PI: F. Jacqueline) deployed in Bay of Seine in May 2015;
– SAUMONARD buoy (PIs: S. Guesdon and C. Bechemin) in Pertuis Charentais;
– D4 buoy (PI: R. Verney), developed in PREVIMER project. This system could be deployed in different sites following scientific needs.
(2) Measurements on board opportunity vessels
• RECOPESCA network (on board fishing vessels).
(3) Les profileurs côtiers
• ARVOR-C and ARVOR-Cm (André et al., 2010).
