In the sediments these ranged from 8-219 x 10. cm. for heterotrophic flagellates. Maximum values are in the range of those for temperate shallow marine bottoms.

On the basis of species abundances, three station groups could be distinguished each corresponding to a subregion of the shelf: an inner shelf, a midshelf and an outer shelf station group. The average depth increased from 20 m for the inner to mo

In the northern part of the study area upwelling phenomena were observed in the subsurface layers below 50 m depth; upwelling water did not reach
