For the Askaryan channel you want a dense dielectric material (dense to have a big target, dielectric so tht radio can propagate). On Earth, that means glacial ice, sand or salt. Antarctica has a lot of ice.

Is sea water unsuitable?
Yes, it's pretty much the opposite of a dielectric. It's a good conductor with mobile charges, and cannot support any polarization.
But it's good enough for ANTARES/KM3NET to see Cherenkov light, which I believe requires a dielectric medium.
