The DYNALIT national observation system (SNO DYNALIT)
Most of the academic players active in the coastal theme on a national scale are found within the DYNALIT national observation system (SNO - Service National d’Observation) supported by INSU, the French national institute for universe sciences. DYNALIT manages the long-term acquisition, collection and harmonisation of high-quality metrological data from 26 workshop sites (sandy coasts, cliffs and river mouths) spread along the whole French coastline.
- Sandy odds : Agon, Pointe de Gatseau, Pointe de La Coubre, Pointe d’Arçay, Espiguette, Maguelone-Aresquiers, Merville-Franceville, Porsmilin, Pays de Monts, Baschamps, Hyères, Guisseny, Suscinio, Dunkerque Est, Biscarrosse, Truc Vert, Anglet, Ermitage (La Réunion).
- Cliff : Mesnil-Val, Vaches noires, Ailly/Puys, Socoa
- Estuary: Rhone, Loire, Gironde, Seine
Observatoire de l’Univers (OSU) : Institut Universitaire Européen de la Mer (Brest)
- 8 OSU : OSUNA (Nantes), OASU (Bordeaux), PYTHEAS (PACA), OREME (Montpellier), OSU Réunion, IUEM (Brest), Observatoire Midi Pyrénées, Observatoire de Lyon
- 20 Universities : Cote Opale, Caen Basse-Normandie, Le Havre, Brest, Bretagne Sud, Nantes, Bordeaux, Aix-Marseille, Montpellier, Grenoble, Toulon, Pau Adour, La Réunion, Perpignan, La Rochelle, Lyon, Toulouse, Rouen, Angers, Rennes.

The coastline observation system (SO LTC)
The SO LTC coastline observation system is dedicated to analysing the hydrodynamics and sediment dynamics of coastal systems. It is supported by OSU OREME (universe sciences observatory focusing on the Mediterranean area) at the University of Montpellier, the Languedoc-Roussillon DREAL environment directorate, the Languedoc-Roussillon region and the INSU institute for universe sciences.
It was set up to ensure the acquisition, qualification, storage, dissemination and scientific exploitation of long-term, high-quality measurements in coastal areas in addition to their coupling with numerical and forecasting models of coastal hydro-morphodynamics.
The SO LTC is also working on two main international issues:
- the analysis of extreme events such as tsunamis or cylones, with partners mostly in Asia and in particular the THL and NCKU in Taiwan;
- the study of shallow water bodies (SWB) which behave like huge coastlines, e.g. the Lac St Jean in Quebec, Canada, or Lake Chad in the Sahel region of Africa) in close partnership with the University of Strasbourg’s EOST Earth sciences observatory.

The coastline dynamics observation service (SODYC)
The SODYC, coordinated by the University of Caen Basse-Normandie, monitors seven main workshop sites. They also cover secondary sites such as the small bay of Mont-Saint-Michel. This observation service covers a broad range of coastal environments in a tidal sea with different degrees of human influence and varied exposures.
The parameters measured are:
- The X,Y and Z position of the coastline at time t
- Foreshore and near-shore topography
- The main external forcing, particularly hydrodynamic forcing
As regards instrumentation, laser topography campaigns are carried out intermittently, while various sensors operate continuously off the workshop sites.
