PAOC Spotlights

From December 10 to 14, thousands of scientists will descend on D.C. to hear about the latest discoveries in Earth and space science, present cutting-edge research, and make career-long connections. With 24,000 attendees and nearly 2,000 oral and poster sessions, the American Geophysical Union's Fall Meeting is without a doubt the largest Earth and space science meeting in the world.

And this year's meeting has promised to be a meeting of many "firsts." It is the first time the event is taking place in Washington D.C. The first time the conference has hosted a platform, named AGU’s Centennial, dedicated to improving ethics, diversity, and inclusion in the field. And the first look into the many dimensions of science’s impact on society and role in helping society to address challenges.

Amid all of this excitement, you’re not going to want to miss the wide range of research that PAOC members are bringing to the conference. From new work on modeling glaciers to metallic microstructures, here's your go-to guide to PAOC members’ AGU presentations. The full Fall Meeting program is searchable online.
