Carta sedimentólogica da plataforma continental brasileira: área Guamaré a Macau (NE Brasil), utilizando integração de dados geológicos e sensoriamento remoto

Abstract: ABSTRACT. Studies carried on the Brazilian continental shelf are little developed, especially on the northeastern Brazil, and particularly on Rio Grande do Norte State.This work intends to organize the existent information about the sediment cover on the NE Brazilian continental shelf, and to elaborate a sedimentological chart. The used methodology integrated the sedimentological data with remote sensing processing stored on a georeferenced bank. Ten main facies were mapped on the studied area. Siliciclastic s… Show more

“…They are clearly observed by Landsat image or hydroacoustic devices (e.g. VIANNA et al, 1991;TABOSA, 2006;VITAL et al, 2005VITAL et al, , 2008GOMES et al, 2007). Some of these seabed features are observed in both the northern and eastern sectors and may be summarized as follows: 1) Very large longitudinal dunes on the inner shelf (≤ 6 m high, 400 m to ≤ 900 m wide and kilometer scale in extension);…”
