a dark debt on the 22nd and an eddy structure on the 
23rd. The dot has also moved westwards during the 
24h. 
The westward moving large-scale eddy structures 
could also be seen at another occasion by Landsat-2 
CH5 1975-08-08 probably due to pollen, Fig. 4. The 
eddy outside the entrance to Oresund is seemingly 
rotating anticlockwise. It is not known if the eddy 
enters the strait and complicates the flow pattern. 
It is, however, certain that the eddy is not a local 
phenomenon but has been generated far away in the 
Baltic (Jonsson, 1984).

As the resolution of NOAA is too small for resolving 
any details of the flow in Öresund one has to resort to 
Landsat imagery (especially Landsat-5) and the rest 
of the Öresund flow information is based on a Land 
sat-5 passage of 1984-05-13. Fig. 5 shows a TM 6, 
360 m resolution image of the whole of Öresund (at 
09.35 GMT) and for comparison a NOAA-7 CH 5 full re 
solution image from the same day (at 14.52 GMT) is 
also depicted, Fig. 6. For the Landsat-scene cold 
water is dark whereas the opposite is true for the
