ディスカバリー遠征
In 1901, Koettlitz volunteered for Robert Falcon Scott's Discovery Expedition to Antarctica, as physician and biologist. Many of his samples are held in the archives of the Natural History Museum, London. His assistant on this trip was E.A. Wilson, later surgeon on Scott's ill-fated Terra Nova Expedition. On a trip he led across McMurdo Sound, Koettlitz discovered two glacial features later named after him: the Koettlitz Glacier and the Koettlitz Névé. For his role in the Discovery Expedition, Koettlitz was awarded a medal from the Royal Geographical Society.
