“Until now these changes in ice drift were only speculated upon using computer models,” said Paul Holland at the British Antarctic Survey. “Our study of direct satellite observations shows the complexity of climate change. “ “The Arctic is losing sea ice five times faster than the ...

Retreat of glacier ice from Nares Strait and other straits in the Canadian Arctic Archipelago after the end of the last Ice Age initiated an important connection between the Arctic and the North Atlantic Oceans, allowing development of modern ocean circulation in Baffin Bay and the Labrador Sea. ...
In 1845, the aptly-namedHMS Terroralong with theHMS Erebusset off from Britain towards what is now Nunavut in Northern Canada in a quest to discover the fabledNorthwest Passage–a navigable Arctic route linking the Atlantic Ocean to the Pacific. Its discovery held the promise of global trade,...
Additionally, we discover the existence of a long-term dispersal corridor between the Arctic and western North America. Our results suggest that the initiation and diversification of the Arctic flora might have been jointly driven by progressive landscape and climate changes and sea-level fluctuations ...
But in fact there have been many ice ages, most of them long before humans made their first appearance. And the familiar picture of an ice age is of a comparatively mild one: others were so severe that the entire Earth froze over, for tens or even hundreds of millions of years. ...
A small population survived on Wrangel Island in the Arctic Ocean until 3700 years ago, while the rest of the hairy giants disappeared from their Siberian habitat some 10,000 years ago. A long-standing theory proposes that early humans hunted the woolly mammoth to extinction. On the other ...
Here's the history & mystery of the Northwest Passage The Northwest Territories is the western gateway to the world’s most elusive watercourse – the Northwest Passage, traversing the icy waves of the Beaufort Sea and threading the choking channels between the High Arctic Islands. For centuries...
After recovery of the aqueous phase, DNA was precipitated using isopropanol at room temperature, and washed with ice-cold (−20 °C) 70% ethanol and resuspended in nuclease-free water. Barcoded Nextera XT V2 libraries (Illumina, San Diego, CA, USA) were made with dual sequencing ...
