Difficult ice conditions slow Swedish icebreaker’s expedition to the North Pole

The icebreaker Oden will drift near the pole for a month as part of a research expedition.

A Swedish icebreaker on the way to the North Pole encountered heavy ice conditions before stopping just before the North Pole.

The Swedish icebreaker Oden embarked to the North Pole from Svalbard last week but encountered difficult ice conditions not seen in one and a half decades.

The captain of the Oden icebreaker described the ice conditions as the most difficult in the past 15 years.

The pack ice the ship encountered was very dense, piled together through a months-long northward ice drift in the Central Arctic Ocean, meereisportal.de reports.

Overall, however, the Arctic’s summer sea ice extent is again very small; the Oden did not encounter the ice edge until 82 degrees north.

The dense ice pack left hardly any patches of open water for the ship to navigate between the massive ice floes.

However, about 200 kilometers before the pole, ice conditions improved with the Oden encountering younger, thinner ice and tracks of open ice left by a Russian icebreaker plowing the area a few days before.

About four miles away from the North Pole, the Oden eventually had to stop its journey since a massive ice flow on the top of the Pole prevented the onward journey, meereisportal.de reports.

However, the researchers managed to find a suitable ice floe for their studies, which they will conduct in the High Arctic for the next few weeks.

Oden as drifting research station

While the researchers and crew on board carefully observed the ice conditions on their trip, the main purpose of the Swedish- and American-led expedition is to use the icebreaker as a drift station close to the North Pole.

For a whole month the research teams from many different countries will collect data about the polar atmosphere. The location is ideal in order to keep disturbances away from the delicate measurement tools for clouds and aerosols.

A team from the Alfred Wegener Institute will also investigate the characteristics of the sea ice and upper layers of the ocean deploying prototypes of new technical instruments on the ice.
