The magnetism of Antarctica

This under-documented expedition was a pivotal moment in the annals of polar exploration and was the starting point, in historical terms, of revealing the great unknown continent of Antarctica. It was the first time in nearly 70 years since Captain James Cook had circumnavigated Antarctica, that a Royal Naval voyage of discovery had ventured so far South. They set a new 'furthest south' record in the process beating the one set up by James Weddell in a whaling ship in 1823.
