ConclusionsConclusions Obtained are high resolution temperature profiles, more stations than in 2003
The layers bellow 50m to the bottom at the west side have been as usually colder than the same layers at the east side.
The conditions at the west side are caused by a flow of colder deep water from the north..
The warmer conditions on the east side of the south Adriatic transect are caused by the flow of LIW through the Otranto Strait.
The waters of the south Adriatic transect in the year 2006 have been slightly colder than in the year 2003 which was, according to meteorological data an exceptional year, with especially warmer summer, but colder winter.
Near real time observation can inprove oceanographic forecasting
Air temperature daily mean course Air temperature daily mean course from from the the ship meteorological station ship meteorological station and coastal meteorological stationsand coastal meteorological stations..
Air temperature from shipborn meteorological station and sea temperature from XBT measurements during the last XBT campaign in October.

-Monday 20h – Tuesday 17h
-(Rijeka-Split (630h)-Dubrovnik route)
-Tuesday 23h – Wednesday 7h (Dubrovnik - Bari trensect)
-Wednesday 22h – Thursday 7 h (Bari – Dubrovnik transect)
-Thursday 20h – Friday 17h (Dubrovnik-Split (630h)-Rijeka route)
Data processingData processing
1. Data validation
(the procedure developed in EACE project)
2. Data comparison with regular meteorological stations
(Dubrovnik, Lastovo, Palagruza, Bari, etc.)
Use of the standard procedure for processing of meteo parameters
Processing and comparison of data values along the transect at the predefined interval
