On January 9, 1909, a polar exploration team led by Sir Ernest Henry Shackleton reached the farthest point south ever traveled by humans. This southern location was 88 degrees, 23 minutes south longitude, 162 degrees east latitude. The team was 97 nautical miles away from the South Pole, but the Antarctic weather was too severe for them to safely go on.
The Nimrod Expedition, named after Shackleton’s ship, was one of several trips made by explorers during the “race to the pole.” A rival expedition led by Norwegian explorer Roald Amundsen, would reach the South Pole only three years later. These Antarctic explorers mapped the last unexplored continent. They also made important discoveries about the plants and animals living in this remote region. Today, Antarctica is regularly visited by cruise ships and is home to international research stations that provide us with important data about global climate change.
