Primeiros Resultados Do Sonar De Varredura Lateral Em Águas Profundas Rebocado Próximo Ao Fundo Marinho

High resolution geophysical data has provided important results for petroleum industries facilities. Petrobras has been<br>acquiring deep towed sonar data since 1997 in all brazilian basins to obtain further detailed information of the sea floor to<br>support pipeline instalation. The seafloor imaging system (SIS-3000) described here uses the CHIRP technology to<br>provided high resolution sonar images and CHIRP subbottom data profiles. The SIS 3000 system is composed by two<br>subsystems as follow: tow vehicle and shipboard eletronics. This paper will present an overview of the deep towed<br>CHIRP sonar and some initial results in the Campos Basin.
