Single-beam deep-water multi-frequency echosounder
Purpose
The multi-frequency single-beam echosounder is designed for seabed profiling at depths up to 6 000 meters
Device appearance
OLE - 12
OLE - 33
OLE - 200
Objectives
- Depth measurement and absolute sea depth determination at the sounding point, profiling of seabed terrain along the vessel track, and generation of bathymetric maps
- Water and seabed backscatter coefficient evaluation
- Water column analysis: detection of vertical thermal layers, thermocline boundaries, and mixing zones
- Data acquisition, visualization, and archivation
