About This Book

A first-person account by the expedition surgeon and anthropologist that chronicles a scientific voyage into largely uncharted Antarctic waters, the charting of new coastal regions, and the ship’s entrapment in pack ice leading to an enforced wintering through the polar night. The narrative combines seafaring detail, daily life and hardships aboard the vessel, incidents and losses, and systematic observations in meteorology, geology, oceanography, and natural history, and it concludes with an appendix summarizing the expedition’s scientific findings.
