About bathymetry application
The optional bathymetry application can be used on the Simrad ME70 Multibeam scientific echo sounder.
By adding the bathymetric application to the Simrad ME70 Multibeam scientific echo sounder you get a true dual purpose Multibeam echo sounder. The resulting system will provide two main functions:
•  a scientific multibeam echo sounder with calibrated split-beams for fishery research
•  a hydrography multibeam echo sounder system for seabed mapping.
Note
With the hydrographic option installed, ME70 may produce input to the bathymetric system when running in fishery research mode. As a result the accuracy level will not meet the hydrographic standard in this mode.
When you use the bathymetric application with the Simrad ME70 beamformer, a fan of beams similar to what is customary for hydrographic multibeam echo sounders is created. These beams are processed by the Bathymetric Processor Unit. This is an advanced bottom detector computer normally found in the hydrographic multibeam echo sounders provided by Kongsberg Maritime AS.
The soundings generated by the bottom detector computer are transferred to the Bathymetric Operator Station and the Seafloor Information System (SIS) application. This ensures compatible data with the other hydrographic multibeam echo sounders. By using the remote control features of the ME70, the SIS application is allowed to control the entire operation.
From an operating point of view, the user interface provided by the ME70 with the bathymetric application is identical to the interface used by the hydrographic multibeam echo sounders provided by Kongsberg Maritime AS.
During bathymetric surveys the Simrad ME70 Multibeam scientific echo sounder is remotely controlled from the Bathymetric Operator Station and the Seafloor Information System (SIS) application.
