%X The objective of this work was to analyze the temporal variability of the chlorophyll-a concentration (Chl) and the sea surface temperature (SST) in the Brazilian Southeast Continental Shelf (BSCS), between January 1998 and December 2006. Images from Sea-viewing Wide Fidel-of-view Sensor (SeaWiFS) and Advanced Very High Resolution Radiometer (AVHRR) were used for the extraction of the Chl and SST data respectively. Besides, Southeast Oscillation Index (SOI) time series for the same period were used. Weekly temporal series (average of 8 days) and normalized anomalies of Chl and SST were generated at five points located on the 100 meters isobath, in front of Cabo de São Tomé, Cabo Frio, Ubatuba, Cananéia and Cabo de Santa Marta. The methodology applied was based on temporal series analysis through wavelet transform (WT) and fast Fourier transform (FFT). The WT and FFT analysis of Chl and SST normalized anomalies showed that the main period of interannual variability were 2,4 years, in accordance with previous studies of SOI time series, suggesting a possible correlation with the El Niño-Southern Oscillation (ENSO) event.
