The question:
is there concentration of induced RF currents near the surface,

Hi Yuri,

Certainly. More so above the surface than below. It stands to reason
as that was the best way for it to get beneath the surface by coming
in from above. Now, if you are searching for another trapped layer
for RF, you have to allow that seawater is pitifully lossy even if it
does present a huge shiny interface. Anything "trapped" in it is
consumed by it in very few feet.

An RF wave has to overcome a huge mismatch to get any power into the
sea. Over the entire HF band that SWR is a minimum 19:1. In the 160M
band the SWR is 75:1.
