Hi, I had been alerted to look at the ROV video in question. As a geologist, I would like to put in my opinion.
Looks like the ALT was stuck at 100 (1.00 ft or 100 ft??) and the COG or Hdg (???) stationary at 130 or 150 deg. Difficult to make out the numbers but
apparent they do no change much.
The Rov did not look like it was scrapping the sea floor. Also if you look carefully the soil bulge developed towards the metallic cylindrical skid,
forming a distinct flat (looks more like a crescent depression) around the skid just before "hell broke loose". If the rov skid was scrapping the
floor, the soil would bulge at the skid first.
Also the camera was facing 130 / 150 deg. So the seabed crest is consistent with the slope at an angle (left) to the direction of camera. (If the
camera was facing north the crest should be on the right - stating this so you know the effect of orientation). Earlier the seafloor looked disturbed
but generally flat without the crest. I see the coords did not change much - so very little ROV movement.
Now the interesting part. You have to refer to my article at
Remember this is a mole hill which I think is caused by mud building up - in other words a mud-volcano. Thus the gas and oil could built up from below
(thru the fault) above the ROV or further downhill. If above, the surficial layer swelled and eventually slide down. Alternatively the gas & oil built
up further downhill and caused a mini landslide. Either way, the seafloor would be seen moving laterally (camera effect) downhill. After the release
of gas and oil, the mud - debris will flatten (not a major landslide to cause a huge scar) and the seafloor will look generally flat with wrinkles
again. The ROV operators must have been observing this phenomenon on a regular basis. Thus they knew when to switch on the lights to record this.
The first time probably scared the lights out of them but after the first few, they are probably expert watchers - just like those geysers watchers at
Yellow stone Park - watching and timing the Old faithful.
