Multiyear Ice

I understand the deal with this now. It is ice that has survived the summer melt for one or more years and built up layers. It hasn't necessarily come off a glacier.


I met some scientists who explained it all and said it's now very rare. There isn't much multiyear ice floating around any more. This is what the arctic used to be like. So this year is very unusual and I am very lucky to have seen it. Now most years you just get first year ice which is much thinner and is salt water because the salt hasn't drained out of it. The ice seems to be thinning every year. Polar bears like multiyear ice for denning in (making a hole and having cubs).
