In somewhat terrifying but hopefully positive personal news, I've decided to purchase an extremely expensive 10x10 booth in the exhibit hall at the American Geophysical Union meeting in December. I'll be selling my gemstone and wire jewelry and art. I hope you'll come find me there.

Happy Isotope Day everyone! 🥳On this day in 1913 Nature published Federick Soddy's paper "Intra-atomic Charge"
www.nature.com/articles/092...
in which he introduced the term "isotope" (coined after a dinner conversation in Glasgow with Margaret Todd the classics scholar). how will you celebrate?🧪⚒️🌊

I have wondered about sound in the ocean ever since I first learned about the SOFAR channel - a weird layer that can transmit certain sound waves thousands of miles. Who uses this thing? Whales? People? Yes. Read more about our noisy oceans in my latest, for AGU's Eos.
