Please note that operations of the Fishing Echo Sounder Simrad EK 60 / 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 60 / 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 60 / 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. |

The system consits of five "split beam" transducers (ES-18, ES-38B, ES-70-7C, ES-120-7C, ES-200-7C) located in the box keel, five General Purpose Transceivers (GPTs), two EK80 WBTs (45-90 kHz, 90-160 kHz) and a computer with installed data acquisition and processing software ER60 and EK80 in room A113. |

Components
The four split beam transducer ES-38B, ES-70C, ES-120C and ES-200C are installed in the keel of RV Heincke. The transceiver and receiver are situated in the Lotgeraeteraum. Three PCs are available for handling of the EK60/80 on the bridge, in the Messraum and in the dry laboratory. Additionally a display is located in the wet laboratory.
The PCs are equipped with the aquisiton and processing software ER60. For further processing the software "echoview" may be used. A dongle is required for usage of the software. The dongle is NOT permanently stored on the ship. Please contact the responsible person for usage of the dongle in advance of the cruise.

Central geographical ship's position and time standard
| Metadata (Metadata Plugin) |
|---|
|
Time synchronising of the computers is regulated via the affiliation to the Windows domain. Additionally, the NMEA-String ZDA is stored in the data files.
The geographical ship's position is transferred to the Master PC together with the NMEA-String and to the data files.
There is no centering of the GPS Position to the transducers. |

Rawdata storage on board
| Metadata (Metadata Plugin) |
|---|
|
Mass data: The data acquisition and processing software ER60 creates rawdata in the mass storage. Please note that there will be a transit from Simrad EK60 to EK80 in 2018 changing data structure and volume.

Data archiving on land
| Metadata (Metadata Plugin) |

After the cruise, the operator transfers the measurement data along with required meta data to AWI after consultaion with the data scientist and AWI Logistics. Then, the data including meta data can be extracted from https://www.pangaea.de/ (for authorized users only). DShip data set can be extracted from https://dms.awi.de. |
