Description 
Summary

The surface area of Albufeira lagoon is about 1.3 sq.km. The depth varies between 2 and 15 metres. In its deeper part the lagoon is utilized for suspended cultures of bivalves, namely mussels. From September 1984 to September 1985, water, microbial and planktonic measurements were taken once a month, at 4 sampling points (surface and bottom). In September 1984, 59 samples were taken for the granulometric study and spatial distribution of sediments and 50 for the macrofauna study. The temporal evolution of macrofauna were undertaken at 10 sampling stations, during 27 months (October 1984 to December 1986). Fishes and crustaceans were caught at 7 stations, once a month during a year. Algae and seaweeds were sampled every three months with a Ponar grab and by means of a quadrat of 0.05 sq.m. The results have shown a highly productive lagoon due to high phytoplankton populations and large praries of Ruppia cirrhosa. The permanent input of nutrients and a large euphotic layer also contribute to the large productivity of this system (10.7 tC/year). 80 per cent of the bottom of the lagoon is mud,three quarters of which is under 2.5 m depth. A general biological impoverishment was observed from downstream to upstream. During this study the lagoon became isolated from the ocean for two months. During this period the system became almost anoxic with monospecific populations. Nevertheless, when the communication with the ocean was established, the system recovered its capacities. It can be considered a self organising system.
