Signal Propagation on sea water path

[orcus]

Hi
Is the propagation of a signal on a sea water path faster than that on a all ground path.
I know that conductivity causes this but what is the equation or theory that explains this effect on speed.
All literature I have got explains propagation INSIDE the medium (in water, in air).
My application frequency is 100 KHz.
Thanks

IN the reference from VEBLL, it looked like the rf moves 0.5% slower than light over seawater. Speed over land in the example looked 8x slower than over the sea.

Seems very small the delay, I guess my 4x-9x slower propagation speed was only off by a factor of 1000. I feel more informed now, which is nice.

"...8x slower..."

I think I know what you mean and I'm sure it isn't 23k miles per second (C/8).

Correct, not 8x speed of light, but 4% slower than light. Or so that's how I interpreted some of what I read.
