\"Ice<\/a>
Ice crystals forming<\/figcaption><\/figure>\n

People are sometimes surprised to learn that ocean water can freeze (but think about it: we’re worried about the melting polar ice cap).\u00a0 Two winters out of the last four, we’ve been able to skate on Mahone Bay after a really cold snap.\u00a0 Salt water freezes at a lower temperature than fresh water, and the saltier it is, the colder it has to be to freeze.\u00a0 I’ve found that it has a softer quality than freshwater ice, perhaps because of the impurities it would contain.\u00a0 But I’m sure it’s just as unforgiving if you crack your head on it!<\/p>\n

I’ve always found crystals fascinating. In my days as a lab chemist I enjoyed doing crystallization, which is done in the lab as a means of purifying a substance.\u00a0 That’s because a crystal is formed when the molecules of a substance lock together in a close pattern.\u00a0 There isn’t much room for anything else in there, between the molecules.\u00a0 Separate the crystals from the rest, and you’ve got a pretty pure product.<\/p>\n

\"Ice<\/a>
Ice on a rock as the tide recedes<\/figcaption><\/figure>This morning there were water crystals forming in quiet corners of the bay.\u00a0 They are supposed to contain very little salt.\u00a0 (Next time I’ll try tasting some!)\u00a0 When salt water freezes on the surface, the ice is relatively fresh (i.e. not salty).\u00a0 Polar bears are observed (not in Nova Scotia!) drinking from puddles on ice floes.\u00a0 Meanwhile, the water beneath the ice gets saltier – and denser, sinking – which makes it even less likely to freeze.<\/p>\n

Of course, these ice crystals I saw this morning melted during the day.<\/p>\n

Watching the changes in the ice on the bay is one of the joys of living in Nova Scotia in winter<\/a>.<\/p>\n
