The South Pole is given to changing
its location every year, making the
exact pinpointing ofits site, a difficult job. But, with the "advent of the
Global Positioning System -the
satellite based navigation system -
the positioning of this southern-
most point on the earth has been
made easier (New Scientist, Vo1149,
No 2016).
The true geographic pole has
to be staked out each year as the
overlying ice sheet moves at a
speed of 10 m annually, carrying
along with it, the markers. Earlier,
the markers were placed 10 m apart
uniformly every year to locate the
site of the South Pole.
