Noisy fish? Lake Superior underwater noises include ships, wind and ... eelpout

Jay Austin and his University of Minnesota Duluth research team were trying to study drifting ice sheets on Lake Superior when they ran into a problem.

Data from the underwater Doppler recording devices was so polluted by background noise that they couldn't determine any results.

Bummer for the ice research. But like any good, inquisitive scientist, Austin was intrigued.

What the heck was making all that racket underwater in Lake Superior?
 

In the case of the fouled ice data, it was ice crashing into itself during the big-ice winter of 2013-2014. But Austin was curious: Are there are other sources of sound under the lake as well? There are reams of research on underwater acoustics in oceans worldwide. But when the UMD physics professor and Large Lakes Observatory researcher started to search for data on underwater sound in large lakes, Austin found nothing.

"It wasn't that it was hard to find. It was nonexistent," Austin said of Great Lakes acoustics research. "There aren't any whales or submarines ... or dolphins out there in big lakes, so apparently no one thought it was interesting enough to look at."
