Joint Reasearch Activities 5:
Mediterranean Products
Marina Tonani & N. Pinardi, INGV
SEADATANET Kick-Off Meeting
Heraklion 8-10 June 2006
National Institute of Geophisics and Volcanology, Italy (INGV)
Objectives:
Preparation and dissemination of regional statistical products like mean,
seasonal and monthly climatological fields and trends from all available
historical and recent data collected over the Mediterranean for various
use with special attention to:
•Cross-Checks of the observation data: detection of residual problems in
data by comparison with the gridded fields values;
•Check of coherence between climatologies and statistics computed in
the different regions, by using different methodologies

Description of work:
•JRA5.1: Coordination of the activity including recomandations for
improving the methodology and for operating it in routine mode with
emphasis on the regional priorities; -INGV, JRC, CLS•JRA5.2: Preparation and dissemination of the best estimates of the
annual and seasonal statistics and trends on grid point of the sea surface
from co-located in situ and satellite data trasferred by regular snapshots
of the interconnected transnational in situ and satellite platforms:
temperature, dynamic height/altimetry, salinity (from 2007 when a satellite
sensor will be available), wind and sea state; -IFREMER, CNR-ISAC, CLS•JRA5.3: Preparation and dissemination of best estimates of the annual
and seasonal statistics and trends on grid points and on the whole water
column from in situ observations: temperature, salinity, current and
biochemical parameters;

•JRA5.4: Quality checks and harmonization with the other regional data
products; elaboration and implementation of the procedures for
monthly/seasonaly climatologies; the procedures will include the run of
the Mediterranean model with climatologies. –INGV, ENEA, OGS …The products will be specified, prepared and validated from existing
practices, in cooperation with all the regional experts of the
Mediterranean countries, with special attention to guidelines and
requirements provided by ongoing programmes such as Mediterranean
Forecasting Project. All the available in-situ and remote sensing data (at
the ocean surface) will be used for computations, and in return, feedback
will be given on the quality of data processed. The communication and
harmonization aspects with other region will be taken charge of by JRC
(P20) and CLS (P14).

AUGUST: SSS shows relevant differences
in the Northern Adriatic Sea and in the
Aegean Sea.

1 PSU of difference in the North Aegean
(MEDATLAS less salty)
More than 1 PSU of difference in the
North Adriatic
(MED6 less salty)
The signal of the rivers run off and
exchange of water at the Dardanells
is different between MEDATLAS and
MED6. Except fot the Aegean, MED6
shows a stronger low salinity signal
close to the river mouth
