What imaginary line forms the northern boundary of Antarctica?

The northernmost point of the Antarctic continent is Prime Head at 63° 12' 48" S, 57° 18' 8" W. All land south of 60 degrees S is governed by the Antarctic Treaty. So, you could say that both 63 degrees S and 60 degrees S -- lines of latitude -- form a northern boundary of Antarctica: your choice.
