Sounds in the Sky: Listening for the <i>Aurora Borealis</i> at Fort Chipewyan
In 1819, British commander John Franklin set out to his first Arctic land expedition in order to survey the northern coast of Canada and to find the fabled North-West Passage. However, part of the expedition's scientific agenda was to investigate the phenomenon of aurora borealis or Northern Lights in the Arctic region. Hearing aurorae was something which eluded most Arctic explorers, and was therefore explained as superstition or an acoustic illusion.
