Weather forecasts could get a lot more accurate thanks to a daring new experiment that will see a massive research ship completely buried in Arctic ice.
The the RV Polarstern will be unable to move apart from when it is carried by slowly moving ice as the treacherous Arctic winter sets in.
Scientists will be protected from polar bears by armed guards during the year-long mission.
The 1,553 mile voyage will allow them to take measurements and observations never possible before.
The bold venture, called MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate,) echoes a famous polar expedition more than a century ago.
In 1893 Norwegian explorer Fridtjof Nansen tried to reach the North Pole by allowing his vessel, the Fram, to freeze in place and drift with the ice.
He and his crew eventually abandoned the ship, which continued to drift past the pole, emerging between Greenland and the Svalbard island group in what is now known as the Fram Strait.
While Nansen’s goal was the Pole, the purpose of the 50 million euro MOSAiC expedition being undertaken in 2019 is purely scientific.
Co-leader Professor Markus Rex, from the Alfred Wegener Institute in Potsdam, Germany, said: “The plan is to travel in summer when sea ice is thin and sea extent is much smaller.
We can travel along the Siberian coast and then make our way with our ice-breaker to the Siberian sector of the Arctic. Then we just stop the engines and drift with the sea ice.
“As the season proceeds the sea ice will grow and by late November we’ll sit in solid sea ice.
It will get colder; the ice will grow in extent and thickness. By then we’ll have set up a network of stations on the ice, some close and some 20 or 30km away.
“We’ll have a network of stations on the ice with a central observatory. The whole thing will drift across the Arctic. During winter it will be completely dark and we won’t be able to move. We’ll just passively drift across the polar cap until we reach the Fram Strait.”
Fifty institutions from 14 countries, including the UK, US and Russia, are taking part in the project.
Knowledge gained from the expedition could transform our understanding of climate change and even help forecasters improve their predictions of weather in the UK, said Prof Rex, speaking at the American Association for the Advancement of Science (AAAS) annual meeting in Boston, Massachusetts.
What happens in the Arctic, where climate change is occurring faster than anywhere else on Earth, has a major impact on the weather in northern Europe and North America.
Yet the forces at work are not well understood because gaining access to the region to carry out ground-based studies is so difficult.
“There are many, many really small scale processes which affect the climate on a regional and global scale in the Arctic which we can’t observe from a satellite,” said Professor Rex.
Strong warming in the Arctic affects weather in Northern Europe because it reduces the temperature contrast between low and high attitudes.
This leads to lighter winds that meander instead of blowing in a more contained circular “zonal” pattern and “more frequent and cold air outbreaks from the Arctic,” he added.
