The whole "kept broadcasting" thing that Boeing/RR have denied could just be misinformation from the US government to hide the capabilities of their acoustic systems.
I'm not talking about a plane hitting the seabed at cruising speed.
A plane ditching into the sea, floating for 10-20 mins then sinking will still hit the bottom with considerable force. Easily detectable by a seismometer.
(this is irrelevant though, as it's likely that the plane didnt ditch into the south china sea)
this => Plane evaporated, no time to mayday.
that is all....
Somehow I doubt we can detect a lump of metal sinking at say 10-20mph and landing on a seabed possibly sand or some other sedimentary bed at some random point in the ocean and then be able to triangulate it
seismometers we use are very sensitive. They can detect motions that are much smaller than the thickness of a sheet of paper or as tall as a room. We can detect ground motion in Missouri caused by increased surf activity as a hurricane or large storm system approaches the eastern coast of the lower 48 states.
Seismometers can be very sensitive. China are using them to detect slight tremors hundreds of miles away.
Here is an example:
This program on CH5 +1 is utter gutter fodder. TERRIBLE music over all clips, TERRIBLE interviewing technique, 3 peoples who obviously answered the call when the 8020958490590428590425 people they tried before said sorry, busy.
GOD what a pish channel.

they wouldnt be able to pick out the plane hitting the seabed amid all the other stuff

Large planes normally break up when ditched in the sea though.
And normally a break up leaves a lot of floating debris and an oil slick.
