Water temperatures do not go below freezing. If you decide on swimming in the antarctic, temperatures vary from from 4°C to 8°C depending on the time of the year. When I went in, I have told it was 5°c.
First inhabited over 10,000 years ago by the Yagan people, the area was first charted in 1826, when accurate maps were produced of the region. In 1833, the boat returned for its second voyage carrying Charles Darwin. It was then, that Darwin recorded seeing his first glacier. Darwin showed great courage during the expedition, after a glacial fall causing a huge wave, it was his intervention that saved the crew. For this act, the ship’s captain rewarded him, by naming a stretch of land called Darwin sound after him.
