title: Antarctic pack ice: boundaries established from nimbus I pictures.
abstract: Television and photofacsimile constructed infrared pictures taken by the Nimbus I meteorological satellite between 28 August and 22 September 1964 were analyzed for indications of the pack-ice boundary around Antarctica. Mean ice boundaries were established around the entire continent from both TV and infrared pictures, from which were estimated pack-ice areas of 19.81 by 10(6) and16.78 by 10(6) square kilometers, respectively; the difference is attributed to difference in subjective discernment of a boundary.
