A northeasterly wind gives rise to pronounced wind shadow patterns behind the islands of Alicudi, Filicudi and Salina. The small-scale eddy, located north of the islands of Salina and Panarea, becomes visible because (natural) surface slicks are entrained by the spiral surface current field associated with the eddy. A headland eddy is also faintly visible west of the thorn-shaped peninsula Milazzo (lower right-hand section of the image). The dark areas in the image are very likely caused
by surface slicks. Satellite: ERS-1
