This study examines the water characteristics of a neritic zone in front of Genova (Ligurian Sea). The samplings were carried out during the spring-summer 1989, 1990 and 1991 in two fixed stations (sea-bed 20m and 100-700m respectively). Some physico-chemical parameters, total bacteria, total and fecal coliforms and phyto- and zooplanktonic biotic communities were considered. On the whole, all recorded values show a generalized oligotrophic state of the water; nevertheless, sometimes an increasing trend of some parameters in the coastal station, probably due to anthropogenic causes, was pointed out. Classification and ordination techniques were applied to define temporal and structural changes of the community.

Abstract

This study examines the water characteristics of a neritic zone in front of Genova (Ligurian Sea). The samplings were carried out during the spring-summer 1989, 1990 and 1991 in two fixed stations (sea-bed 20m and 100-700m respectively). Some physico-chemical parameters, total bacteria, total and fecal coliforms and phyto- and zooplanktonic biotic communities were considered. On the whole, all recorded values show a generalized oligotrophic state of the water; nevertheless, sometimes an increasing trend of some parameters in the coastal station, probably due to anthropogenic causes, was pointed out. Classification and ordination techniques were applied to define temporal and structural changes of the community.
