Sample text

The fragmentary fossil record from Antarctica indicates that a surprisingly wide variety of organisms lived on or around Antarctica. The southern continent has been colonised by a succession of plants and animals that shows signs of being as complex as those on any other continent. Vast habitat areas for occupation by both terrestrial and marine organisms, coupled with equitable climates for very long periods of time, have contributed towards this proliferation of life. Antarctica seems to have been a particularly important dispersal route and undoubtedly served as a major corridor for floral and faunal interchange between the high and low southern latitudes.

(Credit: Bryan Storey) Carboniferous Ice World 289 Ma ancient Gondwana supercontinent during the Carboniferous period about 300 million years ago. A thick ice sheet covered much if not all of Antarctica, waxing and waning and depositing glacial moraines, now preserved as thick glacial deposits in the Ellsworth Mountains and in the Transantarctic Mountains. As the ice moved over the underlying land surface, boulders locked in the ice cut furrows and grooves, providing a further record of the passage of these great ice sheets long after they disappeared.

Whilst much of it is uninspiring there are occasional gems. One by Frank Debenham, a geologist with Scott, was written much later (1956) but carries real conviction and mixes religion with the human emotions. 25 26 Discovering the unknown continent The Quiet Land Men are not old here Only the rocks are old, and the sheathing ice: Only the restless sea, chafing the frozen land. Ever moving, matched by the ceaselessly-circling sun. Wild birds go wandering over the face of the snow; Bright, swift, harsh-crying, strange and heedless.
