can the premise be restated as follows:

"Could an insulated wire in a lossy conductive medium [AKA ocean water]
near the surface be modeled as a slot antenna in a lossy plane?"

No. To my knowledge, a slot antenna requires a thin plane, which an
ocean doesn't resemble. I imagine you could make one in a solid like a
chunk of metal, but believe that the hole depth would have to be a
substantial fraction of a wavelength.

if there is such an effect what is the best way to "catch the RF waves"
grazing the shining ocean surface. More like - can it work besides just
being modeled?

Not sure what effect you mean. But NEC-4 models interactions at, above,
and below a medium like water with reasonable accuracy.

I have been using "dog loop" antenna, originally RF dog fence around 3/4
acre lot, which is basically wire loop burried about 1 inch below the
surface. It has about 600 ohms and works like a goofy Beverage, low noise
pickup and still delivering reasonable signal on 80/160. That's why this
bugs me, like using floating antenna?

I think you'll find that a buried antenna will work more and more poorly
as the ground conductivity gets better and better. As an extreme, how
well do you think it would work if buried in an Earth-sized chunk of metal?

Just wondering if there is any potential in this or if anything was written
up in the antenna books pro or con.

I think you're on your own. The path is clear for you to be the first to
make great discoveries! Just be sure to take a little time off along the
way to do make those coil measurements.
