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 Hydrosweep DS3 is a deep water multibeam echosounder ideally suited for seabed mapping in deep water up to full ocean depth based on a sonar frequency between 14 kHz to 16 kHz. Beside bathymetric depth information from 10 m to more than 11,000 m, sidescan data and backscatter data for seabed classification are acquired.
