yes, I'd noticed the same thing. Right now, Enterprise ROV 1, which is watching one side of the LMRP cap, is showing a depth of 4,960 ft. Skandi ROV
2, watching the cap from the other side and therefore stationed at a virtually identical "real" depth, is showing 4,932 ft.
Query: could the outflow from the well be affecting the gauges' ability to take "true" sea water depth readings? I don't know, but the thought
just occurred to me. Here's my reasoning: an excess of lighter materials in the surrounding waters might
cause this small-percentage
difference in what we see.
It seems to me that even a minor change in water density could result in "non-true" readings: we know that excessive gas in water can affect the
buoyancy of ships because the water is less dense, so could not this outflow be causing similar pressure variations in the immediate environment of
It would be handy if we had either an ROV operator or a submariner who could clarify this for us.
Regardless of the reasons, for practical purposes we have to assume that the depth readings we see cannot be relied upon as accurate enough to
determine any rise or fall in the sea floor.
EDIT to add: actually, if the amount of oil/gas/hydrates being released into the water is
affecting its density and therefore the gauges, then
this becomes a very useful way of monitoring the escaping (non-captured) outflow. When the gauges show the ROVs are not so deep (but in fact
they're right where they were before), it could mean there are more products contaminating the surrounding water.
(End of edit.)
