Fossil Forest
A ossified woods , one that lived between 2.6 million and 3 million long time ago , in the Canadian Arctic , could thrive again , say scientists who suggest by 2100 the climate there would be quick enough to allow such ontogenesis . Here , Alexandre Guertin - Pasquier , of the University of Montreal , at the study site on Bylot Island in Nunavut , Canada , at the origin of the fieldwork in June 2010 .
Bylot Island
The tree in the ancient forest , understand from the pollen samples , are usually found in area where the yearly average temperature is about 32 degrees Fahrenheit ( 0 degrees Celsius ) . Currently , medium temperature on Bylot Island ( the theater of operations site bear witness here ) bulk large around 5 degrees F ( minus 15 degree C ) .
Extreme Science
The foot camp on Bylot Island , where even during the summer , the researchers had to hold up extreme conditions , including gusting winds of 50 mph ( 80 kilometer / hour ) and freezing temperatures .
Magnetic Sediment
A distinctive peat and forest sample distribution roll up from the ancient timber on Bylot Island . The research worker analyzed the samples for pollen , which would reveal the plant / tree species , as well as the charismatic iron within the stone stratum . Since " magnetic sediment " lines up parallel with the Earth ’s charismatic field at the time , something that has changed several times , scientists can expend the results to forecast an age for the level .
Layers of Time
distinctive stratigraphic exposure of sediment studied by the researchers for pollen contentedness . The smash lines correspond to the adjunction between the dissimilar units separate in science laboratory based on grain size .
Arctic Delivery
Material is delivered via helicopter in 2009 during the occlusion of the Bylot Island base camp .
Mummy Trees
Fossil timber of a similar long time have also been found on Ellesmere Island , where mummy trees were reveal by a melt glacier in the Canadian Arctic , and prove here . The spindly , mummified trees showed signs of stress , which was likely the effect of a changing mood ( from glasshouse to an icehouse of sort ) as well as the seasonal digest darkness at the top of the human race .
