3. E2-M3A MAIN PECULIARITIES
E2-M3A is based on the italian buoy BOMA (project supported by a national initiative)
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

4. a multiparametric probe
SCIENTIFIC PAYLOAD
BOMA payload is limited to :
meteorological parameters;
 a CT at surface level;
a sampling system:
a multiparametric probe
a nutrient analyser
that makes available onboard the buoy water from 5 different depths (25, 50, 75, 100 and 200 m),
A multiparametric probe and a nutrient analyser (nitrate) are connected to this system.

7. DATA FLOW AND TRANSMISION
E2-M3A Buoy
Automatic transmission of daily summary file
Daily automatic notification via of the technical status of the buoy
Automatic notification via of alarm conditions
Water detect in each of 3 compartments of the buoy
Buoy displacement out of the safety circle
ACTION: notification is sent with a maximum delay of one hour. The will be send hourly until the disappearing or removal of the alarm condition
