CARACTERIZAÇÃO TEXTURAL DOS SEDIMENTOS SUPERFICÍAIS DE FUNDO E DINÂMICA SEDIMENTAR NA BAÍA DE GUANABARA, RIO DE JANEIRO
Resumo
Abstract
Ninety-two bottom surface
sediment samples were collected in the Guanabara bay using a van-Veen
sampler. They were analyzed for grain size distribution and organic
matter. From the association between the bottom morphology and sediment
characteristics, it was possible to establish the sedimentary dynamics.
This allowed a division of the bight into three sedimentary zones: a
south, sand-dominated zone of relatively high wave and current energy, a
north zone characterized by very calm conditions and clay/mud
deposition, and a central zone of mixed sedimentary characteristics.
