Bathymetry Mapping in The Batu Ampar Waters, Batam: Using Teledyne Odom MB1 Multibeam Echo Sounder (MBES)

Batu Ampar waters, Batam are waters that are in the Riau archipelago, Indonesia. These waters are waters that are very often crossed by cargo ships in shipping goods between provinces. Bathymetry mapping in Batu Ampar waters is the initial activity to obtain accurate depth value information, as a preliminary study for the determination of bottom waters sedimentation. The purpose of this study is to determine the value of bathymetry and determine the type of Batu Ampar waters, Batam, Riau Islands. The method used in this study is the underwater acoustic method, using research instruments namely Teledyne Odom MB1 Multibeam Echo Sounder (MBES). The results of bathymetric mapping in Batu Ampar waters that have been corrected show bathymetry values classified as shallow waters with a depth range that is (- 3 to -10.5 meters), with the measured waters area being 775,094 m2, and having a type of bottom water sediment which is dominated by sand-based sediments
