How Preservation Works
In order for these specimens to be researchable, the ice has to be frozen solid at exactly -1 degrees celsius or lower. Arctic ice is so clean and pure that it can actually withstand temperatures below freezing without cracking for sustained periods of time. Sustained periods of time being tens of thousands of years. Think about putting an egg in your freezer for a month. When you take it out and let it thaw, it’s still a perfectly good egg. In conditions like these, the egg is a woolly mammoth, and the freezer is the entire northern tundra.
