ABSTRACT
The locational problem for Antarctic explorers is one of life and death. Principal causes of misperceptions of location, misperceptions of landscapes and seascapes, and incorrect attributions to distances and landforms result from many causes, and often impede survival. Instrument problems, particularly those associated with the compass, problems of reliable longitude estimates, and mirages have been significant factors throughout the history of Antarctic exploration. The discussion will begin with the compass, and then move on to longitude and mirages.
