It is being billed as the biggest single Arctic research expedition ever planned.
Germany is going to sail its 120m-long research vessel, the Polarstern, into the sea-ice at the top of the world and just let it get stuck so it can drift across the north pole, according to BBC.
The 2,500km (1,550-mile) trip, to begin in 2019, is likely to take a year.
Researchers hope to gather valuable new insights on the region where Earth's climate is changing fastest.
Last month the extent of Arctic sea-ice was the lowest ever recorded for a January (during the satellite era), with temperatures several degrees above the long-term average.
Prof Markus Rex will lead the so-called MOSAiC project.
