Lewis Gordon Pugh, an arctic swimmer who holds world records for the longest swims in the coldest waters, credits his amazing feats to mental prowess and tough training. Scientists released a study last month in ScienceDirect (the Journal of replica Corum 63123.701102 watch Thermal Biology) documenting his body temperature during arctic swims and found some pretty incredible information. Pugh can raise his body temperature, without any physical exertion, to a staggering 101 degrees before diving into the icy water, a feat that keeps his heart from going into cardiac arrest at the shock of entering the water, according to an article in the New Scientist.
Before a swim, Pugh spends up to four hours a day working with a mental coach to prepare himself for the swim. In 2005, Pugh swam a kilometer in 18 minutes near Petermann Island, the most southern swim ever recorded. Most people would replica Corum 02120.102200 watch die in just a few minutes in those conditions. Pughs done more than just insanely cold swims, he also kayaked 750 miles to the geographic north pole this past September. Pugh says he does it to raise awareness about the effects of climate change and the shrinking ice caps. (And because hes a bad ass.)--Melanie Lidman
A group of scientists have discovered subglacial mountains under Antarcticas ice according to Reuters. The find will help them to understand how the polar ice sheet might react to global warming, thus raising sea levels around the world. The newly discovered Gamburtsev Mountains have a topography similar to the Alps.“The surprising replica Corum 60420.015605 watch thing was that not only is this mountain range the size of the Alps, but it looks quite similar to the (European) Alps, with high peaks and valleys, said Fausto Ferraccioli.Ferraccioli told Reuters the mountains would have been ground down had the ice sheet formed slowly, but the presence of jagged peaks could mean the ice buried the landscape in 2.5 miles of ice rather quickly. --Ivan Miller
