just so you can see how much biological activity is
going
on even without active flows. I suspect these are schools
of euphausids or amphipods.
I haven't stabilized for heading as the output is extremely
noisy and doesn't reflect the real motion.
The animations use images based on a 5 frame stack to
suppress speckle. Thus a ~ 2.5 second period per image.
At the playback speed of this animated gif, this is ~ 10x
faster than real time.
The forward looking imagery is created at 25cm resolution
and the downward looking imagery is created using a 5cm
resolution.
