this is the image from the northern line that actually
captured the flow while it is in the channel.

Along Track Volume Scattering Sections:
The following figures represent vertical sections showing
the acoustic volume scattering directly below the vessel as
it steams along one of the three survey lines.
The data are exactly co-registered along the X axis
with the plots above.
Note that there are three tracks:
- 125m to the north of the channel axis or
- 125 to the south of the channel (that way looking at
the over bank flow), and
- directly along the axis (to look at the main channel
flow).
