Several IW packets are clearly visible on ERS-2 SAR image taken on 2 September 1996 at 02:02 UTC. They appear to propagate in at least three different directions. Some of the IW packets are oriented approximately parallel to the depth contours (blue lines). Two packets propagate northwestward. They contain about 10 rank-ordered solitons with monotonically decreasing distance between them (from about 4 to about 0.5 km) as may be inferred from the sections A and B. A packet on the upper left propagates onshore. It may be assumed that dark bands in this packet where the NRCS values decrease to -12 dB and less are due to the appearance of biogenic slick in the coastal zone. Some interaction is observed among packets propagating in different directions.
