Stations on drifting sea ice are still the only option for scientific data acquisition in areas not accessible to icebreakers. The FRAM-2014/15 Expedition using a hovercraft as the scientific platform and manned by two persons presents a new strategy where the key words are mobility and low cost.

The ice station was deployed from icebreaker Polarstern near the North Pole and it drifted down towards northeast Greenland for about 11 months. The unusual drift path crossed Lomonosov Ridge five times. This ridge is a submarine mountain chain longer than the Alps of central Europe.

Along the way, we obtained data for incoming and outgoing radiated energy to the ice surface, energy flux from the water to the underside of the ice, temperature and salinity in the water column, sea bed photography, sediment cores, and 1000 km of seismic reflection measurements. This was achieved in spite of ice activity which forced camp relocation four times including total destruction of the camp area two times.

Yngve Kristoffersen is Professor at the Department of Earth Science, University of Bergen.
