Global warming: ice caps, much less dense than previously thought

18 May 2009 No Comment

Arctic – The explorer Pen Hadow is studying the ice cap to assess the extent of climate change. After traveling 400 km towards the North Pole, he found that the ice was much less dense than scientists expected.

Catlin Arctic Survey is the first polar expedition with the aim to measure the effects of climate change. Over 16000 observations on ice conditions were achieved, including 1500 measures the thickness of the ice with a hand drill. The average measurement was 1.77 meters thick, suggesting that most of the ice was formed during last year and not a great period of time. However, scientists thought, ice found were accumulated over several years, with a thickness of at least 3 meters. In addition, Mr. Hadow said that the ice cover will be further reduced this summer.

The raw data of the expedition, funded by the Prince of Wales, will be transferred to scientific organizations such as NASA, the University of Cambridge and the U.S. Navy, to be analyzed. Today, the volume of Arctic ice is at its lowest and Pen Hadow surprised that the old ice had already disappeared, “The mean measurements of 1.77 meters bring more questions than answers” he says .

Mr Hadow, the explorer Ann Daniels and photographer Martin Hartley made a long journey of over 400 km in 73 days but could not reach the North Pole because of extreme weather conditions where the temperature reached – 40 ° C. “It was very difficult on a few occasions, but we persevered,” said Hadow.
