Two  acoustic instruments were  used i.e., ELAC Seabeam 1050D with a frequency of 50 kHz and Simrad EM 12D with a frequency of 12 kHz.  Data acquisition was obtained by using the hydrostar software in Baruna Jaya 3 and 4 research vessels. CARIS HIPS and SIPS6.1 softwares were used toprocess the data of bathymetry. Amplitude and backscatter data were obtained by data processing on the MBSystem. Data visualization in 3-D was performed using the Fladermaus 6.2 software (personal license of Djoko Hartoyo). Seamount form was assumed as a cone with an elliptical base to calculate the dimensions. The result showed an under water seamount of 320 Km from the southwest of Bengkulu city at -4°22<sup>’</sup>9.16<sup>’’</sup>latitude and 99°25<sup>’</sup>01.47<sup>’’</sup><sup> </sup>longitude. The seamount height was ± 3,968 meters and had two peak separated at ± 3,050 meters. Seamount peaks located at ± 1.270 meters below sea level. The major axis was ± 50,240 meters and the minor axis in this seamount was ± 5,644 meters</p> <p>Keywords: seamount dimension, bathymetry, backscattering, Bengkulu Waters</p&gt;}, number={1}, journal={Jurnal Ilmu dan Teknologi Kelautan Tropis}, author={Fahrulian, Fahrulian and Manik, Henry and Hartoyo, Djoko}, year={2013}, month={Jul.} }
