Multibeam Echosounder (MBES)

German: Fächerecholot (Multibeam)

Gear construction: Acoustic Transmitter and an array of hydrophones on the hull of the ship

Dimensions:

Deployment: Sound waves are transmitted from the hull of the ship and the reflected signals from the seafloor are detected. By the measured two-way travel times and the known sound velocity profile (e. g. from the CTD) the water depths of several points on the seafloor can be calculated.

Maximum Depth: 11,000 m

Follow-up work: Cleaning of erroneous values and grid creation

Samples / Results: Raw and processed data as well as bathymetry and backscatter maps of the seafloor
