Note
titleAttention:

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.

Summary

Sensorweb integration
urnvessel:heincke:net_soundersnetsounders
contenttypeSummary

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.

0Rawdata
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.
