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

|
The net echo sounders are used for information about the status of fishnets deployed in the water. Information about depth of the net, distance to seabed and amount of fish coming in are provided. Small sensors are attached to the trawl and deliver data to the ship where they are received by hydrophones. The SCANBAS365 system can be used together with the SS4 catch sensor, the SS4 door sensor and the TE40 trawl eye available on RV Heincke. |

Components
The transducer of the Scanmar Fishnet Sounder system Scanmar sensors and the battery charging equipment are stored in the Umformerraum. Two hydrophones are permanently installed on the hull of the ship. Working places are The working console with SCANBAS365 installed is situated on the bridge and in the Messraum. ScanBas System is installed on the PCs. It analyzes and visualizes the data.

Central geographical ship's position and time standard
| Metadata (Metadata Plugin) |

|
The Scanmar system receives GPS and time information from the active scientific GPS receiver (usually Trimble) via the the GPS distribution. The data are stored in the NMEA data stream of the Scanmar system |
Rawdata storage on board
| Metadata (Metadata Plugin) |
|---|
|
The Scanmar data are made available via a terminal server. To access the data use any TCP/IP client program e. g. PuTTY or Hyperterminal. For further instructions see manual "Scanmar_datarecording_FIELAX.pdf". The data recorded from Scanmar is in NMEA format and can be converted using the software KonvScanbas.exe. The Scanmar data are not transferred to DShip.
