Approaching the Northern coast-region, we meet a different aspect. The upper- 

 most 20 m:s are considerably fresher at S. Skag 8 than the rest and hold a mixed flora 

 of partly meridional, partly septentrional type. The fresh affluents ha ve allowed de- 

 velopment on spöt in both groups. In the f irst one, we f ind Rhizosolenia (fceröensis v. ) 

 fragilissima at a maximum of 1140 ind. per. 1 in the surface, and in the second Thalassio- 

 trix nitzschioides, which has begun its »f lowering » earlier here than at the south-eastern 

 stations. In greater depths, the flora is very poor.
