What kind of tools/instruments are used to measure the thickness of the ice?

Hello Sammy!
How is ice thickness measured? Good question! Yesterday I went out onto the ice with Alice Orlich from University of Alaska, Fairbanks. I watched her measure the ice thickness. First she drills a hole with an auger (a giant drill, like what is used to make holes in the ice for ice fishing). When she feels that she has drilled through the ice into the water underneath, she pulls the auger bit out of the hole and inserts a clever measuring device called an ice toggle.

Thanks so much for following along. Happy Summer!
