(Hydrografy of the stuarine í lagunar complexo of de Cananéia (25ºS í 48ºW), São Paulo, Brazil. III - Influence of the cycle)

Abstract

DIURNAL VARIATION and VERTICAL DISTRIBUTION of salinity, temperature, transparency and dissolved oxygen of Cananéia Estuary are presented. The data were collected at 8 stations from 1973 to 1980 throughout a period which varied from 4 to 26 hours, and at intervals of an hour approximately. It was observed that the longitudinal, vertical and temporal distribution of those parameters is affected by the tide cycle both in BEFORE and AFTER the dam-building across Valo Grande. The range of variation in salinity decreased AFTER that dam-building and so the renewal rate of the waters in the estuary has probably changed.
