I take it this is a large 1/4 wave antenna for low frequencys.  You
won't get a ground plane much better than the radials in sea, but you
can use an LC network to match the transmitter (actually the feed line)
to the changing impedance of the antenna.  This will make the
transmitter much happier, but it won't make the antenna work any better.

Not that I am aware of.  :-(  Maybe you could use copper pipe instead of
wire?  Outside of that, the only thing I can think of is to switch to an
antenna system that doesn't need a ground plane  e.g. a dipole.
