Arctic scientists begin historic expedition



Arctic marine geologists were a strong presence in the small city of Tromso, Norway, this summer. Scientific parties and crews for three icebreaker research vessels were joined by representatives of the scientific and executive committees of the Nansen Arctic Drilling (NAD) Program. As many of the world's leading Arctic scientists gathered, preparations were made for what some consider to be the most ambitious scientific expedition to the North Pole ever. Arctic '91, a six-nation research expedition in the Barents and Laptev Seas north of the Soviet Union, will collect valuable data for studies of global warming.
