Who discovered the North Pole?

From the summer to the winter the amount of ice in the Arctic Ocean doubles from 3 million square miles to 6 million square miles. The smallest of all the oceans was explored by those looking for trade routes between the Atlantic and Pacific Oceans. But, the first to reach the North Pole was American Robert Peary in 1909 on dog sleds.

Nowadays travelers searching the Arctic Ocean need ships with powerful bows and engines needed to penetrate the sea ice.
