VALIDATION OF THE DIGITAL ELEVATION MODEL (SRTM) WITH GNSS SURVEYING APPLIED TO...
Scalco,Patricia Andréia Paiola; Iescheck,Andrea Lopes; Corrêa,Iran Carlos Stalliviere; Scottá,Fernando Comerlato; Oliveira,Rafael Mastracusa deAbstract Between 2013 and 2014, a kinematic positioning based on the Global Navigation Satellite System (GNSS) was carried out for this research work. This GNSS survey resulted in 275916 points with tridimensional coordinates in the cross-border basin area of 58205 km2 called Mirim Lagoon Hydrographic Basin, located in south of Rio Grande do Sul (Brazil) and west of Uruguay. This study aims at showing the metho...
Paleochannels related to late quaternary sea-level changes in Southern Brazil
Weschenfelder,Jair; Corrêa,Iran Carlos Stalliviere; Aliotta,Salvador; Baitelli,RicardoThe geological evolution of the continental shelf and in the coastal zone of southern Brazil during the Quaternary period is addressed in this study. High-resolution seismic records obtained at the Patos Lagoon revealed the presence of channels that deeply dissected the coastal zone before the formation of the modern, low-relief, coastal plain. Two periods of channel incision are inferred, based mainly on seism...
Estruturas rasas na margem equatorial ao largo do nordeste brasileiro (Estado d...
Silva Filho,Wellington Ferreira da; Castro,David Lopes; Corrêa,Iran Carlos Stalliviere; Freire,George Satander SáA área pesquisada localiza-se na plataforma continental da margem equatorial atlântica, ao largo do Estado do Ceará, formada durante a abertura do oceano Atlântico Equatorial (Aptiano). O mapa gravimétrico residual evidencia estruturas do arcabouço crustal continental ao largo da área estudada, em especial o Lineamento Transbrasiliano e sua continuação offshore (Lineamento Transversal). As bacias da margem cont...
