It has been a landmark weekend here in Bloomington: @iuearth.bsky.social has released the first-ever weather balloons at IU! Part of our contribution, led by Prof. Travis O'Brien, to the Atmospheric River Reconnaissance project to better understand extreme rainfall in the U.S.

Students: it's happening! Coming in the second half of this semester, for the first time at IU, weather balloon launches! Course flyer attached -- although registration for course credit is not required to participate. (Reach out to us if you'd like to participate but outside of the course.)

New in @science.org: Natural hazards aren’t “one and done.” They alter the landscape, changing the likelihood of follow-on events. We argue there’s an urgent opportunity for geomorphologists—working with other disciplines—to better understand and forecast cascading hazards.

A year ago today, we were treated to a total solar eclipse here in Bloomington. Photos from our big day, from graduate student @paleodanny.bsky.social (1), faculty member @codykirkp.bsky.social (2,3), and an instrumented tower set up by the Indiana Geological and Water Survey (4).

Portrait-mode photograph of the sky during a total solar eclipse. A few street and building lights on at the bottom, otherwise the horizon is deep orange and fades to black at the top. Photographer: Danielle Peltier.
