Shackleton's Voyage of Endurance
Mapping Terra Incognita
United States Geological Survey with joint support from the National Science Foundation, Antarctica Advanced Very High Resolution Radiometer (AVHRR) map
Modern map

Scurvy and dog teams are a thing of the past, as exploration of the final frontier of the 20th century affords a new view of the last great unexplored region of the 19th. Orbiting the planet 14 times each day, a NOAA (National Oceanic and Atmospheric Administration) polar-orbiting satellite equipped with a radiometer—sensing visible, infrared and near infrared electromagnetic radiation—circles the globe and transmits data back home. Arcing 517 miles overhead, the AVHRR scans nearly half the continent in a single orbit. To reveal areas hidden by cloud cover on various passes, 63 imaged sections were mosaiced together to form this map.
