Researchers from more than a dozen nations prepared Friday to launch the biggest and most complex expedition ever attempted in the central Arctic — a yearlong journey through the ice they hope will improve the scientific models that underpin our understanding of climate change.

The 140-million euro ($158 million) expedition will see 600 scientists from 19 countries including Germany, the United States, Britain, France, Russia and China work together in one of the most inhospitable regions of the planet.

Arctic - Epicenter - Climate - Change - Markus

"The Arctic is the epicenter of global climate change," said Markus Rex of Germany's Alfred Wegener Institute for Polar and Ocean Research, who will lead the expedition. "At the same time the Arctic is the region of the planet where we understand the climate system least."

Packed full of scientific equipment, the German icebreaker RV Polarstern will leave the port of Tromsoe in northern Norway accompanied by a Russian vessel to search for a suitably large ice floe on which to anchor and set up base.

Days - Sea - Polarstern - North - Pole

As the days get shorter and the sea freezes around it, the Polarstern will slowly drift off on its own toward the North Pole while rotating teams of 100 scientists spend two months each conducting research on the ice.

Stefanie Arndt, a sea ice physicist who will join the mission in mid-February, said the unique advantage of this expedition compared with others is the fact that researchers will be able to observe processes in the Arctic across an entire cycle of seasons.

Transition - Winter - Spring - Time - Ice

"What's particularly interesting is the transition from winter to spring," she said, a time when the ice is normally too thick for ships to reach the Central Arctic.

Recording changes in the density, size and type of snow will...
