An analysis of the species composition and abundance using the Bray-Curtis similarity index showed rather distinct assemblages reflecting water types (fig. 8). The OSW was quite distinct, sharing only some 25% similarity with other two water types. This particularstation (FK001) had only 7.5% similarity with an upwelling station (FK019). Wi...
