Attention:

Please note that operations of the Multibeam Echo Sounder Hydrosweep DS3 requires experienced scientific staff on board and can be only operated upon request. The system is not operated by the ship's crew. Request operations with the Multibeam Echo Sounder Hydrosweep DS3 to AWI-Bathymetry and AWI-Logistics in sufficient time prior to the cruise and clarify the data transfer after the cruise.

Summary

The Multibeam Echo Sounder uses several frequencies to map the topography of the seafloor. It also provides information about the texture of the seafloor as well as the structure of the water body.
