Those Actic expeditions to measure ice shrinkage have a habit of getting trapped in the ice!
I don't think that this is any indication that ice shrinkage isn't happening. The problem there is not so much the amount of ice, but that it is getting pushed around by wind and ocean currents. So you cruise in through a big gap in the ice, then the wind changes and the gap closes up behind you. Another gap the same size opens up somewhere else, but you can't get to it.
