I went with Jason Dobkowski and Chris Cook to the Toolik Outlet where they were installing a conductivity sensor.

Toolik Lake is thawing from the winter freeze that was about 2 meters thick. Toolik Lake's top layer ice is thawing and breaking apart and much of the ice is going downstream.

While the lake thaws it creates what is called candle ice.

Candle ice develops in columns perpendicular to the surface of the lake. They make a clinking sound when the candles are broken apart and float in the water bumping into each other.

DJ - I love the sound that the candle ice makes! Thanks for sharing. I hope you are having a great time - can't wait to hear more about your research and other adventures!

Candle ice is my favorite sound in the Arctic. I would love to record it to listen to in my office in Oregon.

I concur! The formation and sound of the ice is fascinating!
