@esty Cool. Does "artificial" means you made it yourself? Is this regular light microscopy? What makes those colours (some sort of thin film effect?, polarized light) ?
@esty Thanks for the extra info. Even the small crystals are quite beautiful in that polarized light set up. I didn't realize that there were sea ice macro/meso/micor-cosm experiments, but now that you mention it I think I can imagine the utility. Is it a way to confirm/identify the conditions that would give rise to the types of features observed from non-artificial cores?
@danwchan Yes. Sea ice is an incredibly complex medium since each (discretised continuous scale) temperature change has an associated change in water molecular v. ice molarity, and with that a change ionic strength for example. The more concentrated the brine pockets inside the ice become, the further they are removed from seawater: they can no longer be assumed as dilute solutions on top of which salts start crystallising!
