|Ice in Resolute Bay|
2018 will go down as a rough year for ice in the eastern Canadian Arcric, particularly along the classic route of the Northwest Passage that so many who sign up for adventure cruises seek most keenly. It's been both an obstacle -- forcing the re-routing of numerous ships -- and an active threat; in the worst instance crushing and sinking a yacht (the French-flagged "Anahita") near Fort Ross on the eastern end of the Bellot Strait. And, as in previous years, a very large and heavy plug of it has rendered the area around the Victoria Strait impassable by nearly any vessel short of a heavy icebreaker, cutting off the legendary "last link" and preventing completion of any planned transits of the Passage. Indirectly, by forcing the re-routing of larger vessels such as One Ocean's Akademik Ioffe, the ice also may have played a role in her running aground on what was apparently an uncharted shoal or submerged rock.

Some who misunderstand the way ice forms and melts, or don't realize how complex a system it forms with land, winds, waves, and currents, may scoff at warnings about climate change and a warming Arctic -- not realizing that, even as warming puts more thermodynamic eneregy into the north, such energy can readily propel ice -- by speeding the calving of bergs off glaciers, increasing winds and currents, and pushing ice more densely together -- making conditions worse rather than better.
