Here is a LINK to a PBS show about polar bears in the Beaufort Sea, but it is about more than that. It was very informative, if you're interested.
Also, I have been adding news links about this to an older post and I probably shouldn't have just kept going back and editing and updating it but I did so there. You can revisit that post if you're interested in further news on the subject.
We are 52 days from sailing and less than that before departure for Anchorage. Getting excited!
