Hello, Here is a message for anyone who has had a shot at making their own ice core this week.
What to look out for:
- If you have a thinner layer this represents a year with less snow.
- If you have a layer with cracks in it this represents a year that was warmer – the cracks happen when the weather warms up and cools down.
- If you have a layer with something in it… it could be volcano debris that has blown across the Arctic. Or it could be pollution of some kind.
Now you can see how the ice cores help the researchers find out what it was like in previous years in the Arctic.
Show us your ice cores on the blog!
