Abstract

Coastal lagoons play an important role in regional ecosystems. This work aims to raise historical aspects of the main changes suffered by the Saquarema lagoon (RJ). One of the most relevant changes was the opening of a permanent channel to maintain communication between the lagoon and the sea. For that, it was necessary to build a guide to stabilize its opening. This change brought about major changes in the dynamics of the ecosystem. In addition to detailing the historical process of the lagoon, the present study also evaluates the changes and impacts of the artificial opening, comparing periods prior to that construction. Finally, it is hoped that this work will serve as a basis for the guidance of formal authorities and reinforce the need for adequate management and monitoring of this ecosystem.
