Dort and two graduate students, Leonard Woolsey of Pueblo, Colo., and Jeff Honderich, of Eudora, made that trip to continue studies, which Dort began on earlier trips, concerning climatic changes in the last few thousand years. "ANTARCTICA IS basically an arid region," Dort said. "It is so cold there is very little snow which falls in a year. "During these cold spells, glaciers become stagnant. They don't grow or move. In a warmer period snowfall increases and the glaciers get larger and move "So, fluctuations in the size of glaciers is one way of measuring climatic changes in the past," he said. Dort said that deposits of oceanic mineral salts found in the rock and soil in front of glaciers was another indication of a change in climate. During a cold period there is more ice on the ocean and so there is less salt carried onto the land, he said. During warm periods, more is deposited. "Through these differences we can tell when a change has occurred," he said. Dort said that another way to detect a period of change was to study the glaciers' internal structure. A deformation or folding of the ice indicates an earlier warm period, he said. DORT AND HIS assistants worked mainly along the coastal mountains. Their camp was about four to six thousand feet All three of Dort's trips were made during the summer months, December and January, when Antarctic temperatures ranged from 20 degrees above to 47 degrees below. above sea level. There have never been any native human inhabitants of Antarctica and there is no animal life on land, Dort said, adding that seals and penguins abound, but live off the sea. The only plants are small patches of moss or lichen, and even microscopic organisms are scare, he said. Dort said that he would like to write a book about the recent history of Antarctica but that he would probably spend the next couple of years writing reports for scientific journals. National Strike Committee Is Drawn to KU An anti-war group is organizing war protesters across the country in an effort to bring about a nationwide strike of transportation, businesses, and public facilities on October 15 and has appealed to groups at the University of Kansas for support. The aim of the group, the Volunteer Committee of the National Strike for Peace, is to interrupt transportation and businesses to prove to the Nixon Administration that the majority of citizens are against the war in Indochina. The date for the strike, October 15, was chosen because it is a working day falling between the beginning of school and the Congressional elections, and because of its impact as the first anniversary of the October 1969 Moratorium.
