But the knowledge amassed by his team has been used by scientists for 100 years. BY ERIC NILER Special to The Washington Post A century ago, British naval Capt. Robert F. Scott and four members of his polar expedition trudged across the forbidding Antarctic landscape, “man-hauling” sleds across 800 miles of ice and snow in a desperate push to make it back to their base. The Englishmen were suffering from frostbite, malnutrition, dysentery and probably heavy hearts: They were coming home with the knowledge that a competing expedition, led by Norwegian Roald Amundsen, had beaten them to the South Pole. But halfway back to their base, Scott did NATIONAL SCIENCE FOUNDATION something quite Upper Beardmore Glacier photographed by Comdr. Jim Waldron USNR (ret.) during Austral summer extraordinary.

Since then, scien- tists have concluded that these currents form a natural barrier that has allowed Antarctic marine life forms to develop along their own evolutionary paths. Scott’s scientists at both the winter quar- ters on Ross Island and on ship voyages also pulled up dozens of examples of strange, previously unknown sea life. • Weather balloons launched daily by meteorologist George Simpson and other members of the expedition recorded temperature, wind and barometric pressure data that scientists are still using today as a base line to measure climate LARIS KARKLIS/THE WASHINGTON POST change.
