The Southern Brazilian shelf: general characteristics, quaternary evolution and sediment distribution

Abstract: S to 22o S the Southern Brazilian shelf constitutes the only part of the Brazilian shelf with a subtropical to temperate environment. The studies on the different geological aspects of the area began in the 1960´s and have recently been reassessed after studies related to the determination of the Economic Exclusive Zone. In terms of morphology, the Southern Brazilian shelf may be divided into three sectors, the São Paulo Bight, the Florianópolis-Mostardas Sector and the Rio Grande Cone, characterized by conspi… Show more

“…There are some consensus that the "Southeastern Brazilian Bight -SBB" a large sea embayment in South America continent between Cabo Frio (23 o S) and Santa Marta Cape (28 o 30'S) form special transitional area between tropical and warm temperate regions, that are influenced by water mass of the South Atlantic Convergence Zone -SACS (Mahiques et al, 2010). In this sense, Ubatuba Bay that is located near to the center of this area and that have important fishery landings (Ávila-da- Silva et al, 2007), is an interesting site for collecting and evaluate M. furnieri biological parameters.…”

“…It is characterized by its width, of 230 km, and a gentle slope, of around 1:1,300. The continental shelf break is located around 180 m depth (Mahiques et al 2010). The PICS area is of 3,000 km 2 between 5 and 30 m isobaths (figure 1).…”

“…Como característica geral, o fundo marinho da plataforma continental brasileira apresenta diversidade nos processos de sedimentação e na cobertura sedimentar ao longo da variação latitudinal da linha costa, além de baixa declividade média e largura variável de dezenas a pouco mais de cem quilômetros (BRASIL, 2006;KNOPPERS, 19 96; KN OP PE RS ; E KAU ; F IG UEIR ED O, 1999;MAHIQUES et al, 2010). Apresenta ainda paleodrenagens e paleoincisões recobertas pela atual sedimentação marinha e costeira, seja suavizando a sua presença ou pelo total preenchimento com sedimentos (CONTI; FURTADO, 2009;FAGHERAZZI et al, 2008;BONETTI FILHO;CONTI, 1996;WESCHENFELDER et al, 2008) Esse arquipélago, constituído atualmente por 21 ilhas e área emersa de 26 km2, está afastado a cerca de 354,0 km de Natal.…”
