I think you raise a fascinating question, and I'll be interested to hear more. If I was willing to get off my butt and into my dry suit to do more diving here in Puget Sound
What I CAN tell you is that I was just up in Svalbard (just "slightly" North of you -- at one point we were at 81 degrees N latitude, only about 560 miles from the North Pole!) on a polar bear trip, and our guides were amazed at how much ice was just GONE. Not only were many fjords that they expected to be iced over completely devoid of ice, but some of the glaciers have retreated MILES in the last few years (as you said, this stuff is NOT just this one year)! We were able to go much farther North and East than they have ever been able to go, and even then we saw very little ice... Very disturbing (like Al Gore's movie, only up close and personal!), not just because the polar bears don't have ice on which to hunt, but because it is bound to have many other far-reaching ecological implications...perhaps even as far "South" as Wales...
