If the camera is moving why does the robotic arm stay where it is!
Why does the sea floor actaully go above the hand of the robotic arm?

Hi there, it was me that said about footage of these 'other ROVs' putting an end to the debate, one way or the other.
I've received some minor criticisms regarding my posts on here, and I have criticised the thread myself, so I wondered if I could pose you a question?
Nothing patronising, just a simple, curious question.
You say the plumes of dust - quite a distance from the camera - point to this activity. In your honest opinion, is there anything else that could've caused them?
I've said before that they could've been caused by underwater currents, fish that are just out of sight, or now with mention of these other ROVs, could one of them possibly have kicked up the plume 'upstream' so to speak?
Thanks for your time,
Kyle

IMHO, I think you have it the wrong way round. If the arm pushing into the seabed was causing the ROV to tilt, wouldn't it cause it to tilt backwards first? This would create the illusion that the floor is sinking first. The ROV couldn't have been floating before the 'ground rising' due to it appearing so stable.

Watch the video, and look at the top right, you will see the letters "ALT". This is short of ALTITUDE! The sea floor doesn't move, the ROV moves, and the ALTITUDE of the ROV CHANGES!

To start off, I believe the ROV is not resting on the sea floor. If it was, you would see no movement of the sea floor whatsoever, as the ROV would be connected to it, like my previous elevator analogy. You can see at 1:03 the arm of the ROV is moving on it's own power. Note that this is not the camera panning. The camera remains fixed stationary to the front of the ROV, as you can see by the arm on the right.

This movement may have been done intentionally to 'push' the arm further into the ground, by creating a torque with the thrusters.

It is clear some people have misinterpreted what others are trying to explain. So I have taken some time to create a few images to explain what I believe is happening.

I don't think that proves or denies if the ROV is resting on the sea floor because around 0:16 we can see that the camera has the ability to move independently of the ROV and its arm.

So I guess I'm seeing the independent camera movement and the thrusters stirring up debris although something about the movement of the camera is still questionable to me. It looks fluid and very different from the movement in the beginning besides simply the rate of tilting.
