| Zusammenfassung |
| During the pilot phase of the Mediterranean Forecasting System (MFSPP) (2000
2003), a prototype observing system (Mediterranean Moored Multi-sensor Array
– M3A) was designed, developed and operated in the Cretan Sea for continuous
oceanographic measurements in real time. The main problems encountered were
associated with biofouling, underwater and aerial communication and with the
design of the surface buoy. In the second phase of the MFS project named
Mediterranean Forecasting System Towards Environmental Predictions (MFSTEP)
(2003–2005), the aim was to solve those problems and to consolidate the
M3A. For the minimisation of biofouling a pilot field study was performed
and the techniques of bromine solution and copper shielding were evaluated.
Additionally, the oligotrophy of the Aegean Sea dictated the need to ignore
factory calibrations and to perform site-specific laboratory calibrations of
the sensors. This procedure was proved necessary and produced calibration
coefficients that gave results comparable to the measurements obtained with
the laboratory analysis method. During the approximately five years of
operation, there were 13 scheduled and 15 emergency visits, with a total
duration of 65 days. The acquired experience through the maintenance program
proved that the continuous observation of such a very important system with a
relative low cost is feasible. |
