Dr. Crofton B. Farmer, a scientist at the Jet Propulsion Laboratory, described this finding here Wednesday at the Second International Colloquium on Mars. More than 500 scientists from 14 nations are attending the four-da- y meeting on the campus of the California InsMute of Technology. They are reviewing and analyzing what has been learned about Mars primarily from the explorations of Mariner 9, three spacecraft missions which orbited the planet in 1971 and 1972, and the two Vikings, which arrived in 1976 to orbit Mars and drop the landing craft to the surface. The vehicles have returned photographs and data through a complete Martian year, which is the equivalent of nearly two Earth years. Almont All Dry Ice One of the objects of their investigations was Martian water. Where is it on such a dry, cold planet? What happens to it with the changing of Martian seasons? Soon after the Vikings went into orbit, their remote-sensin- g instruments scan- ned the north polar cap and discovered that the permanent ice cap, exposed during the summer when its winter hood of carbon dioxide frost and fog is absent, is composed of water ice. It had been assumed to be dry ice, or frozen carbon dioxide, because that is by far the dominant gas in the thin Martian atmosphere. Later, when it was summertime in DOWNTOWN the south. Farmer said, scientists expected to find water tec there, too But observations by both the infrared thermal mapping and the water vaxr mopping instruments agreed that the southern polar cap is almost completely dry ice Form of Permafrost Temperatures at the poles range .illv fr.'urt T'c. decrees below zero Fahrenheit in the winter to about 100 degrees below in the summer. However, the weather seems to be slightly milder at the north polar region, Farmer said United Press International Southern New Englands first major snow of the winter Wednesday closed roads, snarled traffic and calused an traffic acciepidemic of fender-bende- r dents. Up to 10 inches was predicted for both southern Maine and New Hampshire, while 6 inches was forecast for Coiuiec-tieu- t, Rhode Island and Massachusetts. Portland, Maine, received neaiiy 8 inches within the span of a few hours. New Englander, who have enjoyed a relatively mild winter, took it all in stride. It could be worse," reasoned a Concoid.

Most Martian water, Farmer said, exists in the form of permafrost beneath the surface. The Viking instruments observed other characteristics of the Martian poles. Farmer said that the permanenl northern ire ran is more extensive than the southern cap.
