Release date- 08102019 - Polarstern, a German research vessel, is about to embark on its icy journey across the Arctic. The four researchers from the University of Helsinki on board will be analysing the Arctic atmosphere and the processes that take place in it, such as the formation of fine particles. Observations carried out during the year-long project will help make increasingly accurate climate change models.

'What we are most interested in is change, as the Northern Hemisphere is changing at such a frighteningly radical pace,' says Research Coordinator Tuija Jokinen.

Jokinen is one of the 600 researchers working on the ship over the coming year, each of whom will spend a period of roughly two months on board. At any one time, the vessel will be carrying approximately 100 scientists. On top of that, getting to and from the ship takes an additional month.

Lauriane Quelever, a doctoral student from the Institute for Atmospheric and Earth System Research (INAR), is already on board for the first stage of the expedition, while doctoral student Tiia Laurila will board the vessel for the fourth stage, Tuija Jokinen for the fifth stage and Zoe Brasseur for the sixth stage, in the summer.

The group has also received training for the demanding conditions of the expedition, such as providing first aid, sea rescue, smoke diving and protecting oneself from polar bears.

Those staying behind will also be kept busy by the project. Mikko Sipila, the head of INAR's polar research group, will carry out measurements during the voyage in the research town of Ny-Alesund on the island of Spitsbergen and at the Station Nord research station in North Greenland. The...
