ODAS autonomous platform of Meteo-Oceanographic monitoring

EuroSITES Project.

Along the oceanographic cruise "EuroSITES I", which was carried out between the 3rd and 7th of December 2008, an ODAS buoy was deployed at ESTOC; this achievement represented an important milestone, as it was the first time that an Spanish mooring was deployed until 3630m of depth. The remote observation platform was produced as part of the continuous observation programme of the Macaronesian marine environment that is carried out by the Operational Oceanography group (OO) of the ICCM. Further to the meteorological parameters, it also provides the physical and chemical real time monitoring of the water column, being able to register high frequency changes in the oceanic properties.

Entirely manufactured by PLOCAN, it provides knowledge about the whole meteorological parameters and allows the physical and chemical real time monitoring of the water column, being able to register high frequency changes in the oceanic properties.

The mooring of the Meteo-Oceanographic ODAS buoy which is deployed at ESTOC includes 5 MicroCATS (Seabird SB-37) units, a nitrate sensor (Envirotech LLC, NAS-2-E NAS-3-X) and a Fluorometer (WETLabs, FLNTUSB). A mooring diagram is shown below.

Meteorological Sensors: Wind module and direction; air temperature; relative humidity, solar radiation (PAR), atmospheric pressure; rainfall

Oceanographic Sensors (placed at 1.5 metres below sea surface): Current module and direction, surface sea water Temperature, Conductivity, Salinity, dissolved Oxygen, Chlorophyll “a” (Fluorometer), Turbidity, Hydrocarbon detection, pH, pCO2
