That is pretty funny.

Relationship between wavelength and idstance to the ionosphere?
Wavefront coherence?

No, it's all related to conductivity, as David Eduardo suggests. The graphs
show that the 5000mmho sea-water conductivity is very nearly the same as the
ideal inverse-km line, but slightly more divergent at the higher frequency. The
less conductivity, per the graph, the more distinctly superior a watt at 540 is
over the same power at 1600. As conductivity is a resistance measurement, the
issue is that a path with less conductivity results in more losses in the
radiated wave, attenuating it more at the higher frequencies. The greater
attenuation, however, probably relates to the laws of physics in the same way as
electromagnetis spectra work at the higher frequencies....at high UHF, for
example, it's the size of the molecules in the air that attentuate the higher
frequencies more than the lower. At MW frequencies, this effect is exacted by
the size of the earth (which also is the reason why groundwaves go
over-the-horizon, as it's the earth which diffracts the wavefront).
