5- Status
E1-M3A
Mooring
The
system operates in the south Aegean (Cretan)
Sea since September 2004 and has contributed
to TOP-1, mainly with delayed mode data due
to problems of the telemetry system.
After the TOP-1 period (April 2006) the
system was recovered for a major upgrade
including all system components: surface
buoy, mooring lines, subsurface sensors. A
WAVESCAN buoy compatible with the Greek
national buoy network has been used and this
includes changes of the telemetry system (Inmarsat-C
and GPRS are now being used) as well as of
the whole data management procedure that is
now compliant with the POSEIDON system.
Furthermore, the observing capacity has been
extended to 1000m depth (previously up to
500m) and due to mooring re-design the new
deployment site, few miles NW of the old
one, has a depth of 1200m (instead of
1030m).
Since late May 2007 the system operates at
its new site and transmits data in near real
time. Data can be visualized through

E2-M3A
Mooring
Unfortunately the
E2M3A system did not supply data to
the first Targeted Operational
Period of the project (MERSEA TOP1),
due to the damage occurred. The buoy
operated in shallow waters during
the TOP1 in order to undertake
various tests of the system
functioning. The system was
re-deployed in the original site in
the southern Adriatic Sea, where it
operated since September 2004.
In view of
the TOP-2 phase OGS
a new
surface buoy and system
configuration, (entirely developed
by OGS, has been introduced with the
aim of reducing the cost of
maintenance)
was re-deployed at the site in open
waters at the beginning of April. It
was reactivated the
near real time data flow for the
open sea data. To reach this, a new
satellite transmission system –Globalstar-
was installed. Furthermore, the data
distribution flow is working fine
which includes the application of
quality control procedures and the
formatting of the acquired data into
MEDATLAS format: this procedure will
be maintained and upgraded to
fulfill the needs of the new
configuration, slightly different to
those originally foreseen.

W1-M3A
Mooring
The system operates in
the Ligurian Sea (western Mediterranean Sea)
since September 2004 and has contributed to
TOP-1 with near real-time data in standard
format (namely the MEDATLAS format)
distributed to the thematic data centre
through the ftp site.
After the TOP-1 period
(April 2006) the system continued to provide
data with the same continuity and quality.
On may 2006 the marine sensors were
maintained and at the end of June 2006 a
maintenance mission was performed in order
to carry out the routinely upgrade of the
instrumentation on board.
In the period June 2006 -
March 2007 no mission was necessary since
the system operated smoothly. On March 2007
the marine sensors were maintained (battery
or sensor replacement, cleaning, etc.)
whereas at the begin of May the standard
maintenance with the R/V Thetis was
performed. |
