Tom, if the entire surface of the ocean went up OR down very suddenly, a 
broad spectrum vertical wave would occur in the atmosphere above it. 
That would be a longitudinal wave...but of course the atmosphere doesn't 
go on forever like the 'stuff that fields are made of' apparently does.

Tom, I seem to be a bit ahead of you here. You are confusing two 
different situations.
The type of wave I am talking about and one which would be generated if 
a STATIC field were to suddenly change due to the sudden disappearance 
of whatever was causing that field. If that could be made to happen, one 
would expect a wave to radiate spherically and symmetrically outwards 
and therefore, without doubt, longitudinally....and that kind of 
'square' change would generate a wide range of frequencies..

The difficult part is envisaging how mass or charge might be made to 
disappear at all so such a wave could be produced. A SN would certainly 
do it...and LIGO should detect SN gravitational waves...Newtonian of 
course. In fact, if such waves DO NOT accompany the visible 
observations, then that would suggest a wide range of wave speeds and 
prove Einstein wrong yet again.

In the case of electric charge surrounded by a symmetrical static field, 
I doubt if there is any known way to cause a sudden disappearance. 
Introducing an opposite charge or moving or shielding it would 
inevitably create a transverse distortion.
