Spitsbergen-Svalbard.com Eas­ter brain­tea­ser: the mys­te­ry sol­ved

The Spitsbergen-Svalbard.com Eas­ter brain­tea­ser – what does the pho­to at the bot­tom show? – has got a lot of nice replies. A selec­tion of ans­wers (my own trans­la­ti­on of tho­se that were sent in Ger­man):

  • Clo­se-up of Hump­back wha­le skin
  • Clo­se-up of Wal­rus skin in black & white
  • Ice sur­face. It loo­ks like some­thing has ground it (like the sur­face at a cur­ling court (Swe­den beco­me world champs yes­ter­day!)). So that has to be my guess. Not a cur­ling court, but a ice cove­r­ed sur­face that been groun­ded in some way. May­be from dog sledge skids?
  • Ice struc­tures
  • Is it fro­zen water from below with trap­ped air bub­bles?
  • A warm item (e.g. a warm kett­le) put on fro­zen water.
  • An aeri­al pho­to of fro­zen mud flats at low tide.
  • I thought fro­zen water at first, but I don’t think that’s right.
  • Not polis­hed con­cre­te?
  • Iced-over stroma­to­li­thes that got a gla­cio­lo­gi­cal hair­cut
  • Nega­ti­ve imprint of a fos­sil fern
  • think it is water over some fro­zen soil or some­thing….
    actual­ly i have no clue even after sta­ring for 30 minu­tes at the pic­tu­re!
    in any case: it is beau­ti­ful! 🙂
  • A true conch in shal­low water?
  • May­be a shoe sole
  • A rather rare iron struc­tu­re on a geo­de (or part of it)
  • Pro­fi­le of a snow mobi­le belt
  • Clo­se-up of ice struc­tu­re
  • A dog in a river bed / ice sur­face

A num­ber of inte­res­ting and sur­pri­sin­gly varied ans­wers! It seems to have been more dif­fi­cult than I had thought, and this shows how much came­ra and lens may help to see things that other­wi­se are hid­den or that we see, if at all, in a dif­fe­rent way. All tho­se who have seen gla­cier ice have had this phe­no­me­non near them (but not necessa­ri­ly seen it and paid atten­ti­on to it).

This is how the pic­tu­re was taken:

What is this? Gla­cier ice!

Spitsbergen-Svalbard.com Easter brainteaser: What is this? Glacier ice!

A macro pho­to of gla­cier ice in an ice cave in a gla­cier, with tri­pod and macro lens, to make smal­lest details visi­ble. The brain­tea­ser pho­to shows very small air bub­bles in gla­cier ice. The indi­vi­du­al bub­bles and chan­nels are smal­ler than 1 mm. The area shown on the pho­to is, in rea­li­ty, an esti­ma­ted 4×6 mm lar­ge, or rather: small. This net­work of air bub­bles was ori­en­ted in a plain par­al­lel to the very clear ice sur­face, about 2-3 cm deep in the ice, which altog­e­ther made it pos­si­ble to pho­to­graph it. Plea­se don’t ask me how exact­ly this pat­tern of air chan­nels comes into exis­tence, I don’t know. Plea­se tell me if you know.

The first pri­ce for “Clo­se-up of ice struc­tu­re” goes to Ste­pha­nie in Scot­land! Ste­pha­nie, the choice is yours!

The second pri­ce goes to Leip­zig and the third one to Swe­den. Congra­tu­la­ti­ons to all win­ners and a big thanks to all who sent their ans­wers! It was fun, and that was the who­le pur­po­se of it.

What is this? Very small bub­bles and chan­nels of air trap­ped in gla­cier ice
