Arctic Issues

I previously posted information about the NOVA PBS/ tv series "ARCTIC PASSAGE". In following the "books and links" from the "ARCTIC PASSAGE" webpage http://www.pbs.org/wgbh/nova/arctic/ , I found three additional very helpful sites concerning Arctic geography subjects including human geography:
