Tara Polar Station embarks on 18-month Arctic mission

Lorient – 19 July 2026: The Tara Polar Station departed its home port of Lorient on Sunday for the first expedition of the Tara Polaris program. The French research platform is to operate in the Central Arctic Ocean for 18 months. Its deployment marks the start of a series of ten consecutive missions through which the Tara Ocean Foundation aims to document changes in the Arctic over the long term until 2046.

The station is designed to become enclosed in pack ice over long distances and drift with it. According to the foundation, it is expected to be surrounded by ice for around 90 percent of the time during a mission. Research will therefore also take place during months of near-total darkness, when measurements in this remote region are particularly scarce.

The focus is on interactions between the atmosphere, sea ice and the ocean below. Scientists aim to record, among other things, changes in ice cover, temperature, chemical processes and biodiversity. They will also study microorganisms and examine how Arctic species adapt to major seasonal differences in light, cold and ice conditions.

The Tara Polar Station is not a conventional research vessel, but a floating laboratory designed specifically to drift in ice. It was built in Cherbourg and completed in April 2025. In summer, the platform can accommodate up to 18 people. Wind turbines, solar panels, battery systems and bio-based fuels are planned for its energy supply.

The Arctic is warming significantly faster than many other regions of the world. However, the Central Arctic Ocean in particular remains only patchily observed because of its remoteness and extreme winter conditions. Satellite data alone are not sufficient there to track processes in the ice, atmosphere and water with adequate precision throughout the year.

International institutions are involved in Tara Polaris I, including the CNRS, the French Polar Institute, the Alfred Wegener Institute, and research groups from Canada, the United States, Switzerland and Denmark. The data are intended to help improve climate models and provide a better understanding of the effects of changes in the Arctic on oceans, weather and ecosystems.

With its departure from Lorient, the platform’s journey to its operational area in the far north now begins. The actual drift research will start once the station is in suitable sea ice. The Tara Ocean Foundation describes the mission as a long-term observation program intended to provide comparative scientific data over several decades.
