The ice floe that the German research boat will be attached to as it drifts around the Arctic for almost a year on the most important Arctic expedition ever has been selected.
In a race against time, researchers found the approximately 2.5 by 3.5 kilometre, slightly egg-shaped ice floe that seems suitable for the mission on 4 October, before the onset of the polar night – the Alfred Wegener Institute in Bremerhaven has announced.
After the hot summer, finding an ice floe of suitable size and stability in the region north of Russia, some 550 kilometres from the North Pole, where the research boat is currently located, was not a simple task.
The Polarstern began its journey on 20 September from the Norwegian port of Tromsø. Some members of the expedition have been exploring the ice floe selected on foot since 28 September. They found an unusually stable area in the northern section of the floe where the ice is over several metres thick. They have dubbed this area the Fortress, and they will build a research camp there where 300 scientists from 17 countries will take turns to participate in the expedition costing 140 million euros.
The researchers will primarily study climate change: their objective is to improve our understanding of the impact of the Arctic region on global climate as it is transformed by climate change. The boat will remain afloat until June 2020, when melting will begin, and the Polarstern will be freed from its icy captivity somewhere between Greenland and Svalbard. Evaluation of the data collected will begin after that.

The oceans play a very important role in controlling Earth’s climate. New research has shown that the planet’s five oceans absorb much more carbon dioxide, one of the gases responsible for the greenhouse effect, than previously thought.
According to a study published in the International Journal of Climatology, Israel’s average temperature has been rising continuously since the proclamation of the Middle Eastern state in 1948, but over the last thirty years the rate of warming has also increased.
Temperatures are rising much faster than the global average in the region of the Mediterranean Sea, and this represents a threat to the food and water resources of the region, researchers have warned in a new study.
The news about climate refugees are alternating sequences of frightening numbers and apocalyptic landscapes that obscure the real face of the problem: the disfigured human fates.
