A fabulous image posted on Facebook today -- taken as the winter really sets in on Blidö in the Stockholm Archipelago. the "pancakes" with upturned edges are formed when a thin sheet of sea ice forms and then breaks up under the influence of wind and small surface water flows (there no real tides here). The broken ice slabs move about, colliding with one another and acquiring the raised ridges on their edges before finally freezing together again as the temperature plummets.
There are MANY forms of sea ice...........
Minus 49 degrees elsewhere in Sweden I gather......
ReplyDeleteYes, it's turning out to be a serious winter this year -- the sort of winter Inger remembers from her childhood......... I don't know the statistics, but I reckon that global warming now means that a COLD winter is just happening once in a decade.
