This ship works in collaboration with the Healy, which is the new American icebreaker. In the western Arctic, in the Beaufort Sea, these are the two ships that are carrying out the study. In the eastern Arctic, between Greenland and Canada, the line is jointly drawn by Canadians and Danes, and not from icebreakers, but right on the pack ice because it is too thick in that place.
Some expeditions have attempted to take seismological measurements from the pack ice, and it proved to be extremely difficult. We have made very little progress in the eastern Arctic, whereas in the western Arctic, with the icebreakers, we have made some progress.
