The sea floor definately moved, it looks like the ROV may have been pumping air into the seabed to help relieve a methane build up. If you have
methane building up just under the surface, but the pressure isnt great enough to break through, then pumping air into these areas would help the
methane break through before it reached a more dangerous level. The only thing that puts me off this theory is the lack of bubbles before the collapse
of the sea floor. Good video catch though S+F for that alone.
