Both the geographic and magnetic South Poles were reached for the first time during the Heroic Age. The achievement of being first to the geographical pole was the primary object in many expeditions, as well as the sole rationale for Roald Amundsen's venture, which became the first to reach it in 1911. Other expeditions aimed for different objectives in different areas of the continent. As a result of all this activity, much of the continent's coastline was discovered and mapped, and significant areas of its interior were explored. The expeditions also generated large quantities of scientific data across a wide range of disciplines, the examination and analysis of which would keep the world's scientific communities busy for decades.
