The present study was held in the Cananéia-Iguape Estuarine-Lagoon System (SELCI). Three anchored stations were performed: two in the main connections with the adjacent coastal area and one in an inner station in the South region. The artificial channel of Valo Grande (VG) is nowadays open and constitutes the most important freshwater source to the system.
The goals of this work were: 1- Study the dynamics of conservative and non conservative properties transport between the SELCI and the adjacent coastal area, in rainy and dry seasons; 2- Study the system metabolism, emphasizing phytoplankton primary (PP) and bacterioplankton secondary productivity (BSP) relationship, as well as the role of transparent exopolimeric particles (TEP) in this relation in estuaries.
Results showed that the SELCI can be classified as an immature estuarine system during dry season and as middle-aged during rainy season. Metabolism was mainly heterotrophic, specially in the North region, where BSP was not related to PP, due to the great inflow of aloctonous organic matter, resulting in a strong modification of this organic matter through the system. TEP were a key parameter in these processes, eventually aggregating diatoms and consequently acting in their transport in South region and sometimes favoring particle assembling in the northern turbidity maximum zone and consequently increasing BSP.
The current PhD dissertation produced three papers(currently in revision)international scientific journals and 18 conference participation, and new papers we are preparing now.Email:juanalba@usp.br
