It’s wild how different elements of nature mimic each other. Just like ice shelves, trees also “scream” (same low frequency hum / vibrations) when they’re parched.
There was a project to estimate changes in ocean temperature via changes in the speed of propagation of sound over thousands of kilometers. The idea was that sound speed in seawater is partly a function of temperature. And there's a kind of "waveguide" in the ocean where the speed of sound in seawater (average ~ 1500 meters per second) is at a minumum because that speed is a function of *both* temperature and pressure; it's a layer known as the "SOFAR" channel. The idea was if you could keep monitoring the speed of sound over years-to-decades you could keep track of ocean warming. see: https://staff.washington.edu/dushaw/heard/index.shtml

Nature, man!

You must be a time traveler and have read an advance copy of part 4 ;)
Jokes aside, thank you for reading and sharing the wash/edu link. Will bake it into my research.
Which research areas have you focused on?
Thank you for this!
Of course, Ryan!
Thanks to all the researchers who dragged themselves out to Antarctica to do all this research.
