Attention:
Please note that operations of the Sediment Echo Sounder Atlas Parasound P70 requires experienced scientific staff on board for permanent supervision of data aquisition and storage. The system is not operated by the ship's crew. Announce operations with the Sediment Echo Sounder Atlas Parasound P70 to AWI-Logistics prior to the cruise and clarify the data transfer after the cruise.
Summary
The Sediment Echo Sounder surveys the upper layers of the seafloor via the reflection of acoustic signals. Depending upon the reflectivity of the sediments penetration depths of about 200m can be reached.
