ME70 Seafloor Characterization and 4D Water Column Visualization
The Simrad ME70 multibeam echo sounder has the potential to conduct simultaneous seafloor and mid-water analysis. This talk will examine one approach to seafloor mapping and bottom characterization using a standard water column mode, which utilizes split-beam processing to realize several independent bottom detections per beam. The limitations of this approach - including the maximum grazing angle for which split-beam processing is useful - will be discussed. Examples of water column data visualizations, and raw data extraction, using a new software tool developed by IVS-3D, will also be presented.
