Experiences of Scott's Northern Party: evidence for a relationship between winter katabatic winds and the Terra Nova Bay polynya

Abstract

The six men of Captain Robert Falcon Scott's Northern Party were stranded on Inexpressible Island (Fig 1) from late February to September 1912. During that period their lives were profoundly influenced by prevailing surface wind and sea ice conditions in Terra Nova Bay. Members of the party lived under the most primitive conditions, enduring more than seven months of strong, persistent winds. The western part of Terra Nova Bay remained largely free of ice in 1912, thus preventing the group from leaving until there was sufficient daylight to cross the Drygalski Ice Tongue. This open water, however, may also have assured their survival for it attracted enough seals and penguins to provide them with a continual though limited supply of food. Despite these adverse conditions some of the men, Raymond Priestley in particular, kept detailed journals which provide the only in situwintertime observations for this area. Analysis of Priestley's wind and ice record provides strong confirmation of our model for the wintertime persistence of open water (a polynya) in Terra Nova Bay.
