Bathymetry is study about ocean depth that relate with the sea level and study about<br />

the topography of underwater structure. Multibeam echosounder is sonar system that<br />

emit sound waves in the shape of a fan from directly beneath a ship's hull. These<br />

systems measure and record the time it takes for the acoustic signal to travel from<br />

the transmitter (transducer) to the seafloor (or object) and back to the receiver. The<br />

different in time taken will describe different depth of the ocean floor. Multibeam<br />

system 2020 are been used in field sampling and Qimera and Surfer 14 software used<br />

to analysis the data.This study will provide some information on basic knowledge how<br />

to operate and analysis multibeam data and also will provide an overview about the<br />

bathymetric map at Vietnam Beach, (Bidong Island) that can be used for future studies<br />

in this field.<br />
