Lefebvre, Alain
The MAREL (Mesures Automatisées en Réseau pour l’Environnement Littoral) Carnot system developed and implemented by Ifremer (French Research Institute for Exploitation of the sea) in 2004 is a moored buoy equipped with physico-chemical and biological measuring devices working in continuous and autonomous conditions. The system is located in the Boulogne-sur-Mer harbor (eastern English Channel) influenced both by marine coastal and fresh waters. The measuring station is equipped with high performance systems for seawater analysis and near real time data transmission. This system records with a high frequency resolution (20 minutes), the following parameters: estimated sea level, gust wind speed, wind from direction relative true north, horizontal wind speed, relative humidity, light irradiance surface PAR, sea temperature, practical salinity, ph, dissolved oxygen, fluorescence, turbidity. For nitrate + nitrite, phosphate, silicate parameters the sampling frequency is set to 12 hours.The MAREL Carnot system is a component of the national high frequency observing network COAST-HF link to the Research Infrastructure IR ILICO.
