Tara Polar Station on its way to the North Pole

The French Tara Polar Station has set off on its first scientific expedition to the central Arctic. On 19 July 2026, the newly developed research platform left its home port of Lorient and began a mission that marks the start of a 20-year international research programme. The aim is to gain a better understanding of the rapid changes in the Arctic Ocean and to document the effects of climate change on the sensitive ecosystem of the Arctic Ocean throughout the year.

The Tara Polar Station is neither a traditional research station nor an icebreaker. The platform, which is around 26 metres long and 16 metres wide, was specially designed to be frozen into the pack ice in autumn. It then drifts for many months with the sea ice currents through the central Arctic Ocean – much like Fridtjof Nansen’s legendary Fram once did, but equipped with state-of-the-art scientific equipment. Its round shape ensures that it is pushed upwards by the growing ice and cannot be crushed by the pressure of the ice.

During the first expedition, scientists from twelve countries will collect data on the atmosphere, sea ice and the ocean. The focus will be on Arctic biodiversity, life in and beneath the sea ice, the interactions between the atmosphere and the ocean, and pollution from harmful substances and microplastics. Particular attention will be paid to organisms that have scarcely been studied to date, despite playing a key role in the Arctic ecosystem.

The Arctic is currently warming three to four times faster than the global average. At the same time, the extent of summer sea ice is steadily shrinking. Many processes occurring during the long polar night have so far been scarcely studied, as expeditions during this season are extremely challenging and risky. The Tara Polar Station aims to close this knowledge gap and, for the first time, provide comparable data series from the heart of the Arctic Ocean over many years. The Tara Polaris programme plans a total of ten drift missions, each lasting several months, through to 2046. Through standardised data collection, the researchers aim to distinguish long-term changes from natural seasonal fluctuations. The data obtained will be used to improve climate models, document developments in Arctic biodiversity and establish a scientific basis for future conservation and management measures in the Arctic.

The Tara Polar Station’s first drift marks the start of one of the most ambitious international research programmes in the Arctic in recent decades. Over the next 20 years, the floating research station is set to become a permanent observation post in the central Arctic Ocean, providing valuable insights into a region that is changing faster than almost anywhere else on Earth.
