Operational forecasting
of ocean circulation and marine ecosystem fluctuations requires
multi-parametric real-time measurements of physical and biochemical properties.
The architecture of a system that is able to provide such measurements from the
upper-thermocline layers of the Mediterranean Sea is described here. The system
was developed for the needs of the Mediterranean Forecasting System and
incorporates state-of-the-art sensors for optical and chemical measurements in
the upper 100 m and physical measurements down to 500 m. Independent moorings
that communicate via hydro-acoustic modems are hosting the sensors. The
satellite data transfer and the large autonomy allow for the operation of the
system in any open-ocean site. The system has been in pre-operational use in
the Cretan Sea since January 2000. The results of this pilot phase indicate
that multi-parametric real-time observations with the M3A system are feasible,
if a consistent maintenance and re-calibration program is followed. The main
limitations of the present configuration of M3A are related: (a) to bio-fouling
that primarily affects the turbidity and secondarily affects the other optical
sensors, and (b) to the limited throughput of the currently used satellite
communication system.
