Growing up, I didn’t know what job I wanted to do. I didn’t know then that I would become a scientist. But today, I am a glaciologist. I study glaciers around the world!

A glacier is a moving river of ice. It flows over Earth’s surface. I moved to Alaska to study glaciers. A place needs three things to have glaciers. It needs snow, cold temperatures, and time. Snow falls and piles up. Cold temperatures keep the snow from melting. Over time, the snow stacks up until it is hundreds of meters thick. Then it turns into glacier ice.  

I study glaciers near Skagway, Alaska.

This glacier in Iceland is seen from above.

Some of my students taste part of a glacier!
