Polar Connect 2026 Expedition Maps Arctic Seabed for Subsea Cable Route
The Polar Connect 2026 expedition is conducting detailed seabed mapping in the Arctic Ocean at several challenging sections along the proposed cable route, including a mid-ocean spreading ridge where two tectonic plates are gradually moving apart .
After departing Longyearbyen, the expedition reached the sea ice just north of 80°N in late July 2026. Experts on board are working together to address the pioneering challenges of laying a fibre-optic cable on the seabed beneath permanent sea ice, bringing together expertise in fibre-optic technology, submarine cable installation, ship design, Arctic navigation, and environmental science .
"I have worked with research activities involving Oden for more than ten years, but this is my first time participating in an expedition," wrote Ulf Jonsell, Expedition Coordinator. "That firsthand understanding is invaluable in helping us reach sound conclusions about the best approach when the time comes to lay the cable" .
