4. Results

6. Comparison of 2003 and 2006

10. Conclusions
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

Thursday 20h – Friday 17h (Dubrovnik-Split (630h)-Rijeka route)

18. Air temperature daily mean course from the ship meteorological station and coastal meteorological stations.
Air temperature from shipborn meteorological station and sea temperature from XBT measurements during the last XBT campaign in October.

19. Position of meteo-station on board:
QUESTIONS
Position of meteo-station on board:
Is it the most appropriate? (Shadow, albedo)
Have we followed all the procedures for automatic meteo stations on board?
Adjustment of measuring interval (10” now)

20. Missing components:
Sensors:
wind speed
wind direction.
