Abstract

Guanabara Bay, one of the most eutrophic tropical systems in tire world, receives large loads of urban and industrial wastes. Its hydrobiology shows temporal trends according to seasonal variations determined by the rainny summer and spatial trends associated to a tidally induced current pattern that create horizontal and vertical gradients. Human impact is strongest along the shores in the inner reaches of the Bay that present high ammonia and phosphorus concentrations (? 650 ?M and ? 308 ?M), and low, transparence (
