Conceição Lagoon: a review on the availability of ecological data aiming new researches on the ecosystem. Conceição Lagoon is one of the major touristic centers on Santa Catarina Island and, as a consequence, it has been subjected to great changes by anthropogenic actions. Research has characterized and evaluated the magnitude of the main contaminants in the Lagoon. A review on the availability of data concerning the ecology of the Lagoon was made, aiming at the development of new researches and complementary studies to better understand the dynamics of this ecosy- stem and to achieve its sustainable use. The Lagoon receives the influ- ence from sewage waste, heavy metals and disordered land occupation. The effect of sea water is strongest nearby Barra Channel, which gene- rates  a decrease in the concentration of some nutrients and a distur- bance  in the aquatic communities. A lack of continuous and long-lasting data on community dynamics, environmental productivity, nitrogen and phosphorus cycles and chlorophyll concentration was observed. Circulation patterns in the Lagoon, as well as the influence of the Barra Channel, are essential information for a proper understanding of the ecosystem’s functioning. A periodic and continuous monitoring program on physical, chemical and biological data is extremely necessary in order to evaluate the environmental changes. This information will be of great importance for future proposals concerning environmental education, restoration and preservation related to the Lagoon.
