The Arctic and the Antarctic are privileged locations for observers interested in understanding how our world is shaped by the forces of nature and the workings of history. These areas have inspired countless humans to undertake epic expeditions of discovery and have witnessed both great triumphs and miserable defeats. As a planetary litmus paper it is at the poles we can detect the effects of natural oscillations and human activities on the global ecosystems.

022 Ships: From Wooden Vessel to Nuclear Icebreaker
What kind of ship is adapted for polar voyages? The early voyages of discovery have been made using wooden ships and the technology evolved up to Nansen's Fram. Nowadays metal hulls are the norm and the vessels are classified in a system of "ice classes". Icebreakers are a world apart and they have their own classification. Some of them are very large and have considerable engine power that allows them to navigate through the polar ice at all seasons . With the opening of the northern routes more commercial ships will be built to an ice class and some are already in service
