• Data acquisition and mission control electronics– distributed architecture (more CPU

each devoted to a specific task)– plenty of interfaces available for

additional payload and communication systems

– low power consumption– mass memory virtually unlimited

E2-M3A MAIN PECULIARITIESE2-M3A MAIN PECULIARITIES

• E2-M3A is based on the italian buoy BOMA (project supported by a national initiative)

SCIENTIFIC PAYLOADSCIENTIFIC PAYLOAD

BOMA payload is limited to :• meteorological parameters;• a CT at surface level;• a sampling system: a multiparametric probe a nutrient analyser

Data processing

1. Automatic transmission of daily summary file

2. Daily automatic notification via e-mail of the technical status of the buoy

3. Automatic notification via email of alarm conditions

•Water detect in each of 3 compartments of the buoy•Buoy displacement out of the safety circleACTION: notification is sent with a maximum delay of one hour. The email will be send hourly until the disappearing or removal of the alarm condition
