Argentina accuses Chile of encroaching into its territorial waters and trying to seize part of the continental shelf. Officials described the move as unacceptable.
These include areas along continental shelf formations where ice is attached to the shore, the National Institute of Polar Research said in a statement.
The country says because the North Pole is connected to the continental shelf of Greenland, and because Greenland is a Danish autonomous territory, the North Pole is Denmark`s.
From the shore line, out to a distance which may be anywhere from a few miles to a few hundred miles, runs the gentle slope of the continental shelf, geologically part of the continents.
