The research aircraft “Polar 5” today concluded its Arctic expedition in Canada. During the flight, researchers measured the current ice thickness at the North Pole and in areas that have never before been surveyed. The result: The sea-ice in the surveyed areas is apparently thicker than scientists had suspected.

Normally, newly formed ice measures some two meters in thickness after two years. “Here, we measured ice thickness up to four meters,” said a spokesperson for Bremerhaven’s Alfred Wegener Institute for Polar and Marine Research. At present, this result contradicts the warming of the sea water, according to the scientists.

Apart from measuring ice thickness, the composition of arctic air was also investigated. With the help of a laser, the researchers studied the level of pollution of the atmosphere by emissions from industrialized countries. In the next few weeks the results will be evaluated. Some 20 scientists from the U.S., Canada, Italy and Germany took part in the expedition. [transl. BJP]
