A joint USSR/Canadian skiing expedition, from Cape Artichevsky on the Severnaya Zemla Islands, Asiatic Russia coast to Cape Columbia on Ellesmere Island, Canada, via the North Pole, took place in March-May, 1988. The North Pole is 980km from Russia and 750km from Canada, a total distance of 1730km. The expedition set out on March 3rd.
This was a scientific expedition to make geomagnetic , glacial and meteorological observations, to conduct experiments in physiology and biochemistry to determine the limits of human endurance. The expedition was organised and financed by Kosmolskaya Pravda (Socialist Youth Newspaper) and the Polar Bridge Company, a group organised by the Canadian participants, supported by commercial sponsors. All communications were handled by Amateur Radio.
