Principal component analysis and morphostructural characterization of a portion...
Duarte, Cynthia Romariz; Cordeiro, Elicius Feijó; Costa, José Higor Batista Araújo da; Sabadia, José Antonio Beltrão; Salgueiro, Ana RitaThis study used Landsat 5 Thematic Mapper (5-TM) images in the morphostructural characterization of the shallow continental shelf of the eastern coast of Ceará (CE), in the Jaguaribe river mouth. The dam built near the river mouth to transpose the water towards Fortaleza, CE, ensures good water transparency since little of the river-carried sediment reaches the sea. The used image was captured on date and time ...
Análise da recepção do sinal VLF da Estação NAA (24.0 Khz) EUA e sua utilização...
Cordeiro, Walber; Cordeiro, Vinícius Feijó; Cordeiro, Elicius Feijó; Castelo Branco, Raimundo Mariano GomesDuring the last decades, several authors have demonstrated the usefulness of VLF (Very Low Frequency) geophysical surveys as a fast and powerful tool on surveying geological structures (faults, fractures, diaclases, contacts, dikes, etc.). Other applications involve mineral prospecting, civil engineering, contaminants identification and especially groundwater prospecting. During this research, it was verified t...
Integração e interpretação de dados aerogeofísicos e de sensores remotos aplica...
Cordeiro, Elicius Feijó; Costa, José Higor Batista Araújo daThis work is an interpretation and integration of the airborne geophysical data and remote sensing in a 1:50,000 scale of the Choró / Quixadá - CE regions. The area is included in the Algodões-Choró Metamorphic Suite (ACMS). This suite is composed mainly by para and orthogneisses, with layers of amphibolites locally intruded by granitic/tonalitic orthogneisses. Field evidentes suggest two main units described i...
