WMB-160F

WMB-160F Screen Shots The WMB-160F is a multi-beam sonar that has been designed to provide users with high definition fish and water column targets as well as detailed information about the seafloor. It uses five viewing modes displayed on four easily selectable screen displays to view the multi-beam data it collects. The screen displays are optimised to view fish and water column targets, to profile the seafloor, or to provide combinations of water column and seafloor profiles.

The following are a selection of screen shots taken during actual sea expeditions highlighting some of the many functions of the WMB-160F and divided into the following groups: Sonar fish school and water column targets ............................................2 Seafloor profiles ..................................................................................6 Shipwrecks and foreign objects ........................................................... 11 Combination viewing modes................................................................ 15

Sonar fish school and water column targets To display fish schools and water column targets, the WMB-160F has three viewing modes available. These are: ►

Sonar View. A 120° port–starboard view of the water column that is updated every ping.

►

Single Beam / Triple Beam. This is similar to a traditional sounder, except that the beams can be dynamically adjusted by the user.

►

Fish Overlay. Fish and water column marks (in colours showing depth) are overlaid onto a grey scale 2-D seafloor contour view.

See Figures 1 to 7 for sample screen shots.

Seafloor profiles The WMB-160F has a number of viewing modes to show seafloor profiles. These are: ►

Contour View. Where the seafloor depth is shown in a 2-D view with depth indicated by colour. The colour scale can be manually adjusted using the Depth Colours box to highlight the required depth.

►

3-D View. Where the seafloor is shown in a 3-D view, with depth again shown by colour. This view can be in North up, Course up, or Free rotate.

►

Backscatter Hardness. This is a 2-D contour view where a greyscale is used to show seafloor hardness changes.

►

Sidescan View. Where both the water column and seafloor are shown in a waterfall style of display.

See Figures 8 to 16 for sample screen shots.

Figure 8 – Contour Display: The vessel is shown in the middle of the display, the colour range is spread between RED at 11 m and BLUE at 25 m. Any depth outside this range is grey. Range scale = 1,800 m.

Shipwrecks and foreign objects Shipwrecks and foreign objects can be shown in both the water column type (sonar, single / triple beam views) and seafloor profiling displays (contour, 3-D, sidescan views).
