Potencial de transporte sedimentar pelas correntes de fundo na região do Canal de Vema (Atlântico Sul)

Abstract: ABSTRACT. Vema Channel is an important passageway to the flow of bottom water between the Argentine and the Brazil basins. The channel morphology causes confinement and intensification of bottom currents that affect the ocean floor through sediment resuspension, transport and deposition, consequently playing a fundamental role in the formation of deep ocean deposits. The main goal of this paper is to evaluate the potential for sediment suspension and transport by the local currents through estimates of nearbed… Show more

“…The RGR is an extensive morphological high reaching 3,500 m from the oceanic crust. This high acts as a significant barrier to the transport of sediments through the Vema and Hunter channels between Brazil and Argentina basins (Kaji et al, 2011;Galvão and De Castro, 2017) (Figures 2, 3).…”

“…Considerada como um extenso alto morfológico, pode alcançar 3.500 m de altura em relação ao assoalho oceânico, servindo como uma grande barreira para o transporte de sedimentos. Este transporte ocorre através dos canais de Vema e Hunter, entre as bacias oceânicas do Brasil e da Argentina, as quais se encontram a norte e a sul da Elevação, respectivamente (Kaji et al, 2011;Galvão & de Castro, 2017) (Figs. 3 e 4).…”
