It is being billed as the biggest single Arctic research expedition ever planned,the BBC reports.
Germany is going to sail its 120m-long research vessel, the Polarstern, and into the sea-ice at the top of the world and just let it get stuck so it can drift across the north pole.
The 2,500km (1550-mile) trip, to start in 2019, and is likely to choose a year.
Researchers hope to gather valuable recent 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:
"The decline of Arctic sea-ice is much faster than the climate models can reproduce and we need better climate models to invent better predictions for the future.
"There is a potential that in a few decades the Arctic will be ice free in summer. That would be a different world and we need to know about that in advance; we need to know is that going to happen or will that not happen?[br]
"Prof Rex outlined the device for the Multidisciplinary drifting Observatory for the Study of Arctic Climate here at the annual meeting of the American organization for the Advancement of Science (AAAS).
The German scientist, who is affiliated to the Alfred Wegener Institute in Bremerhaven, and said the €63m (£54m; $67m) expedition was very nearly all funded,and would have key contributions from international partners.
Other European states, such as the UK, or are involved - so too the Americans,the Russians and the Chinese.
The mission has echoes of the Norwegian explorer Fridtjof Nansen's attempt in the 1890s to be the first person to reach the North Pole by drifting in a ship locked in ice.
A schooner called Tara also traversed the frozen ocean - from Siberian waters to the Fram Strait - in the same way a decade ago.
But the RV Polarstern is an immense science platform and its list of tasks and goals dwarfs those of all previous efforts to work in the region.
"We’re bringing a vessel full with equipment: many, many measurement containers and remote sensing in-situ instruments, or " Prof Rex said.
"We'll choose water,ice and air samples. And we'll set up camps on the sea-ice close to the Polarstern and others up to 20-30km absent. And the whole set-up will drift across the Arctic. That will give us a recent and absolutely fascinating insight into the climate system."
The MOSAiC team even plans to invent runways on the sea-ice so research planes can choose to the air in support of the RV Polarstern.
