Based on your experience from previous trips, how do you prepare and solve problems like members of the expeditions going through the ice?

Great question. The ice thickness varies from several feet in most places to several inches or thinner in some places. Obviously we avoid the thin ice as much as possible. We do not cross ice that we consider to be a significant hazard. Rather we will ski around it or find another alternative. Regardless, we will demonstrate what to do if you fall through the ice during your training. We actually practice this skill on our Polar Shakedown Training. When we cross ice that is relatively thin we cross one at a time, and our guides are always nearby, ready to help. In reality, the risk of falling ALL the way through the ice is small. It's more common to have a foot go through, or maybe get wet up to the knee., etc. Of course it's also possible that you will not see any thin ice during your expedition (especially on short expeditions), or you may find "leads" of open water that you have to detour around. They are quite interesting and so much a part of polar travel that it would almost be a shame NOT to see one!
