ice core
Scientists examine cores of ice, drilled from ice sheets and glaciers. They analyse chemicals in air bubbles trapped inside, and in water of melted slices. There they find evidence of past climate change. We can only imagine what the life forms, trapped for eons in layers of ice, might have looked like.

The viewer of your work might misinterpret what THEY see as 'factual', whereas it is your response to stuff YOU'VE learned and only you know what is interpreted and what is real.
I wish you really could see critters in the ice like that, but sadly it's extremely difficult to see anything. I've tried using a scanning electron microscope to look at particles in ice cores but the particles are mostly dust and below 2 microns. I'd love to look for critters - as I do believe they are there, but I don't know what they would be - probably bacteria and pollen. It's an area of research that has not been tapped into in the ice core community as a whole, mainly because there is so much else to do, and this particular work is extremely difficult to do without contaminating the sample!
