Ice sings - but I only heard it for the first time yesterday. Looking out over the mostly frozen Pennington Flashes and watching the geese and ducks, I heard not quite a wind, not quite a wigeon whistle but a tuneful wail sweeping round from some indistinct point. It was the ice - singing. I'd no idea it did.Is it created by the movement of wildfowl on ice? A Google search tells me that ice-skate blades can cause it - like rubbing the top of a wine glass and causing molecules to move. But I'm not so sure.... To me it sounds more like the movement of air (as in a wind instrument). As the ice moves and water laps it must cause the air trapped between the two to move, resulting in a whistle as is it is forced out along the melting edges and any other gaps. (And is consequently sucked in again.) Well that's my theory. What's yours?
A poem is slowly forming in the gaps.
