Tara Ocean Launches Arctic Expedition on Floating Lab

Six scientists and six crew will depart Kirkenes, Norway, on 14 August aboard the Tara polar station, a 26-m by 16-m vessel that can freeze into pack ice. After an icebreaker clears a route, they will drift eight months across the Arctic, overwintering in darkness with temperatures to -50 °C to collect climate and pollution data before the ecosystem changes.

Since Fridtjof Nansen’s Fram (1893-96), two vessels have crossed the central Arctic. The Tara schooner completed a trans-polar drift in 2006. The new floating laboratory aims to fill the “blank sheet” of biological knowledge identified by director Romain Troublé.

Romain Troublé, microbiologist and executive director of the Tara Ocean Foundation, leads design and fundraising. Co-founder Étienne Bourgois helped design the station. Dr Nina Schuback, a Swiss Polar Institute biological oceanographer, will direct microbial sampling. Scientists from fifteen nations were selected through a process likened to International Space Station crew selection.

The team arrives in Kirkenes on 14 August 2026, waits for an icebreaker in mid-August, then drifts from late August 2026 to April 2027. The leg begins a planned ten-leg, twenty-year continuous expedition.

Funding of €26 million (£22 million) was secured. The vessel’s moon pool enables divers, drones and ROVs to sample the water column.

Scientists will sample seawater microbes, ice algae and microscopic life via the moon pool, aiming to discover new species adapted to darkness and to link biological changes with satellite-observed ice loss. Limited baseline knowledge hampers assessment of ecosystem response to rapid warming.

The data aim to inform policy that safeguards the Arctic from shipping, fishing, mining and pollution, providing scientific evidence for international regulations and conservation.

The Tara Ocean Foundation stresses the urgency of documenting Arctic biodiversity before loss. Romain Troublé notes that physical processes are known, yet the biological component remains a “blank sheet.” Dr Schuback adds that satellite data show rapid ice change, but biological impacts require in-situ observation.

• “We are losing species before we have time to discover them,” — Romain Troublé, Executive Director, Tara Ocean Foundation

The Guardian

• “Dr Nina Schuback It is a race against time: the Arctic is warming three to four times faster than anywhere else on the planet and the sea ice that once protected the region is melting fast, exposing the sea to threats from shipping, fishing, mining and pollution.” — Dr Nina Schuback

The Guardian

• “[but] how often do you get the chance to do something like this?” — Dr Nina Schuback

The first leg starts the planned ten-leg, twenty-year drift, intended to generate data that will support Arctic protection policies.
