Análise do ambiente costeiro e marinho, a partir de produtos de sensoriamento remoto na região de São Bento do Norte, NE Brasil

Abstract: ABSTRACT. This work characterizes the coastal and marine environment morphology of the São Bento do Norte area (NE Brazil) based on remote sensing analysis.Applying digital image processing techniques, that were georeferenced, rectified and processed. The integration of field data to the resulting images (RGB-5-2-1, HSI-PC6-4-2, PC2 e PC4) allowed the identification of the main submerged features and detection of environmental changes on the coastal zone. The area is located in Potiguar Basin between a complex… Show more

“…However, a small variation for northwest was also observed. This current direction is suitable with the historical registers of the winds in the São Bento do Norte region [8,11,13,14], and differs from the observed predominant direction in other areas to the west, as Guamaré, which flow preferentially for northwest [15,16]. In minor amounts, different current directions can also be observed (west, north and northeast).…”

“…It shows an elongated structure with a bending curve form at the west extremity. Echosound profiles and sediments samples from this bedform show that it is about 400 to 600 m width and asymmetrical with steep side facing seawards [14,21]. On the crest the sediments are mainly fine siliciclastic sands moderately to well-sorted, in contrast with the flanks.…”

“…A visualização e interpretação das principais feições da Plataforma Continental Norte do Rio Grande do Norte baseou-se na caracterização geomorfológica obtida na literatura (Vital et al (Gomes et al 2007b Lima & Vital 2006;Tabosa 2006;Tabosa & Vital 2006;Tabosa et al 2007), e foram complementadas com a análise dos dados batimétricos, das imagens orbitais e da construção de Modelos Digitais de Terreno (MDT).…”

“…O sensoriamento remoto se constitui numa ferramenta eficaz para a análise espacial e temporal dos aspectos geológicos, geomorfológicos, pedológicos, uso do solo e cobertura vegetal a partir da interpretação visual e/ou automática de imagens de satélite (Meneses & Almeida, 2012). Alguns trabalhos mostram a importância da aplicação do sensoriamento remoto no mapeamento geomorfológico (Rao, 2002) e em estudos geológicos e geomorfológicos de zonas costeiras (Souza Filho & El-Robrini, 2000;Souza Filho et al, 2005;Tabosa et al, 2007;Vital et al, 2010;Polizer & Rossetti, 2014;Albino et al, 2020;Silva & Lima, 2020).…”

“…Em função disto, Souza Filho et al (2005) destacaram a importância do uso de diferentes técnicas e aplicações do sensoriamento remoto, como os modelos digitais de elevação (MDE), imagens de radar de aberturas sintéticas (SAR), entre outras, na investigação geomorfológica destes ambientes. Tabosa et al (2007) destacaram o uso do processamento digital de imagens (PDI) e do cálculo estatístico das imagens no mapeamento de feições morfológicas de ambientes costeiros e marinhos da região de São Bento do Norte (RN). Para a zona costeira emersa, ressaltaram que a composição colorida R5/G2/B1 do sistema Landsat 7-ETM+ permitiu a identificação das unidades geoambientais com base na geomorfologia, uso do solo e cobertura vegetal (manguezais, solos expostos, culturas, etc.).…”
