Tentative study of flow patterns in the North Aegean Sea using NOAA-AVHRR images and 2D model simulation

A statistical technique for image processing, the maximum cross correlation (MCC) method, was utilized on sequences of NOAA-AVHRR thermal data in order to explore the surface advective current dynamics at the discharge region of the Hellespont in the North Aegean Sea. A 2D numerical flow model was also used in order to simulate the barotropic flow pattern of the surface water layer. The model was forced with diurnal wind fields obtained for the same period as the satellite infrared images. The currents (magnitude and direction) derived from the two methods compare satisfactorily despite the fact that some model simplifications were made.     

Cyprus fisheries

Fisheries make up about 1.7% of the value of the gross domestic agriculture production of Cyprus and about 2.8% in terms of ‘value added’ of this production (1981 data). Production in 1982 was about 1 564 tons, valued at about C£2708000 (Table 1).¹
