Yep. That's about right. But the salt water is at the beginning of the path.
That's the important part.

My view is controversial. A lot of AM geeks don't agree that the soil
conductivity at the beginning of the path affects skywave propagation. The
conventional wisdom is that it affects only the groundwave. But if you think
about what the vertical radiation pattern would have to look like if the
soil conductivity affected the groundwave but had no effect on the skywave
at low angles to the ground, you realize that nothing in nature behaves that
way (or nothing I can think of, anyhow). I'm convinced that if the signal
gets a good start over salt water, the skywave as well as the groundwave is
going to be stronger.
