Attention:
Please note that operations of the Fishing Echo Sounder Simrad EK 80 requires experienced scientific staff on board and can be only operated on request. The system is not operated by the ship's crew. Request operations with the Fishing Echo Sounder Simrad EK 80 to AWI-Logistics in sufficient time prior to the cruise and clarify the data transfer after the cruise.
Data quality of Fishing Echo Sounder Simrad EK 80 is decreased by operating other Echo Sounders. Repeatable disturbances were detected from simultaneously operating a) POSIDONIA, b) Sonar Doppler Speed Log DOLOG and c) Sediment Echo Sounder Parasound P70. Switch off these Echo Sounders for high data quality.
Summary
The sounder operates several frequencies simultaneously thus allowing to detect fish in different depths.
