Trapped in ice, Polarstern scientists have finally returned to dry land
On September 20, 2019, the research vessel Polarstern left Norway for a trip that would last a little over a year as part of the MOSAiC or Multidisciplinary drifting Observatory for the Study of Arctic Climate expedition . As the name of the mission suggests, the ship's destination was the Arctic, and the project saw the participation of hundreds of researchers from around the world.
According to scientists, this expedition, which finally ended last October 12 when the boat was able to return to dry land in Bremerhaven in Germany, was inspired partly because of what the Norwegian explorer Fridtjof Nansen had accomplished in 1893. He was the first to let his ship become a prisoner of the ice and be carried away by the icy sea of the region ofthe Arctic. Its goal was to prove that ships could use ice to explore this part of the world. The MOSAiC expedition is the first modern expedition to reuse the method employed by Nansen. The Polarstern ship was thus deliberately trapped in the ice in October 2019 to be taken towards the North Pole.
According to the researchers, the trip allowed them to witness firsthand the effects of climate change on the Arctic . This region is said to be heating up at twice the rate of what can be seen in the rest of the world. Markus Rex, atmospheric specialist at the Alfred Wegener Institute in Bremerhaven, explains that this expedition has bluntly revealed that the Arctic Ocean was dying.
Equipped with advanced equipment
We can say that expedition MOSAiC is one of the largest Arctic missions ever executed, if we look at the means available to scientists to carry it out. According to reports, the total amount allocated for the expedition was $ 154 million, which was disbursed by the Federal Ministry of Education and Research of Germany and the U.S. National Science Foundation and Department of Energy.
From a material point of view, scientists were able to take advantage of planes and helicopters, as well as all support ships provided by partners including China, Russia or even Germany. As for the measurements themselves, they used a set of complex instruments developed especially for the study of the dynamics of the Arctic sea ice, of ecological systems, and of oceanic and atmospheric processes.
Better understanding the climate
After the expedition itself has ended, now is the time for researchers toe browse and study all the data collected during the trip. They will also calibrate climate models based on this new data.
According to Matthew Shupe, an atmospheric scientist at the University of Colorado, and also co-coordinator of MOSAiC, the base their job is to collect data and transform it into knowledge that can be used to develop and improve models. It is these models that will help us learn more about the climate in the future, and predict the weather. These models are also needed to be able to best represent what is happening in the Arctic.
Global warming is currently one of the biggest problems facing the world. face. With the results obtained during the MOSAiC expedition, let's hope that our new understanding of the climate will somehow establish a plan that will serve to mitigate the effects ofthis phenomenon on our planet.
