The aim of this work is the presentation of a synthesis of available geochronological data for the basement inliers and metavolcano-sedimentary sequences which occur in the southern part of the Apiai Terrane, south-southeastern Brazil. These data, especially those obtained during the last decade, have made substantial modifi cations to the tectonic scenario of south-southeastern Brazil with the recognition of the presence of extensional basins (continental rifts) with magmatism and sedimentation at the late Paleoproterozoic (1790 - 1750 Ma) and of the Mesoproterozoic (1600 - 1450 Ma). These processes started at the late Paleoproterozoic in the Betara, Perau and Apiai Mirim …

In this study, the importance of MODIS sensor multispectral imagery on monitoring coastal and oceanic areas as well as marine ecosystems is demonstrated. As an example, the Todos os Santos Bay (TSB), BA, Brazil, was selected. Four 250m Sea Surface Temperature and Chlorophyll-a satellite-derived images were processed to characterize the TSB in 2009, as well as monthly time-series from July 2002 to January 2010 and monthly maps of 2009 off the coast of Bahia. These results were compared to the Brazilian Water Agency (ANA) discharge data and tidal data. They showed the importance of the latter in physical forcing compared …
