OK, here is the one for the experienced and theoriticians:

How about antenna made of wires, submerged just below the surface of water,
partially salinated (brakish) or sea water. Would it couple to this huge
"water antenna" (variations of insulated vs. bare elements) or connect/tap
to it?

I don't understand. You're asking about the coupling between a submerged
antenna made of wires and a "water antenna"? What's a "water antenna"?
How close together are the two antennas?

Any submerged antenna would have to be very shallow if it's to receive
signals from above the water -- the attenuation of fields traveling
through salt water is very high (~16 dB/foot at 1.8 MHz). If it's very
deep, it might as well not be there at all.
