Curiously Polar

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.

078 The Conundrum of Time


Time can be a tricky conundrum in Antarctica. There are such extreme cycles of day and night, with close to 24 hours of light in the summer and the opposite in winter. And as you move towards the south pole, lines of longitude get closer and closer together until they meet. The result is that the normal indicators we use to help tell the time aren’t particularly helpful. For scientists working in Antarctica, they generally stay in the time zone of the port they departed from, but this can mean that neighbouring stations are on very different time zones if they come from different countries. To add to the confusion, Australia’s Mawson, Casey and Davis stations are all on different time zones! For travelers on expedition cruise ships, we generally stay on Ushuaia time - unless we’re traveling to the Falkland Islands and South Georgia. Then we adjust to their local times, changing as we travel south.
