Winter shipping in the Canadian Arctic : toward year-round traffic?

With the rapidly melting sea ice in the Arctic, and developing shipping traffic, emerged the idea, popular with the media, that sea ice would soon be completely dominated by first-year ice, and would thus be comparable to ice present in the Gulf of St. Lawrence: this would allow for the setting up of shipping year-round along Arctic passages. In fact, contrary to this idea, even with the vanishing of multi-year ice, ice conditions will remain very different in the Arctic from ice prevailing in the Gulf. Besides, naval technology certainly helps overcoming challenges of ice navigation, but they do not mean it is economically or technically much easier. Year-round shipping in the Arctic remains a difficult challenge to overcome
