"Sea Change" in the Arctic

In an article in the November Atlantic ("Sea Change") that includes the above graphic, Scott Borgerson describes some of the economic and political implications of the Arctic Ocean becoming navigable due to the melting of the ice cap.

Presumably, a beneficiary of a more navigable Arctic would be Baffinland Iron Mines (TSX: BIM.TO), the speculative Canadian junior iron mining company that had been a pick of Aaron Edelheit (at least until Mitsubishi declined to participate in Baffinland's round of financing last year).
