    Probably for a couple of reasons.  The Antarctic icecap does
have glaciers, and any that contain meteorites will drop them
where they melt, while the Arctic is a floating icecap, and
does not have any glaciers.  Also, if the Arctic icecap
occasionally melts during interglacials, and meteorites
it contains would drop to the bottom of the Arctic Ocean.
