Many congratulations to Patrick Chindandali, who successfully defended his MS last week and deposited the final version of his excellent thesis today! Congrats, Patrick!!!

Our Introduction to Oceanography class took a 5-day field trip to The Ocean, visiting some spectacular spots near Big Sur and Monterey. Some major storm systems battered the coast while we were there, so the weather was.... epic. But so was the geology, biology and oceanography 🙂.

Thousands rallied in Flagstaff, Prescott Valley and at nearly a dozen other demonstrations against the Trump administration across northern Arizona this weekend.

A couple of SES undergrad and grad classes have recently ventured to the San Juan Mountains in Colorado to learn about fundamental geological processes that have shaped this spectacular range. The fall foliage wasn't bad either :)

Fun afternoon of science on Saturday at the NAU open house in the Flagstaff Festival of Science! SES students and faculty showcased everything from volcanos and earthquakes to insects. Thanks to our amazing students for sharing their knowledge and to everyone who stopped by!

Many congratulations to SES Prof @rengellia.bsky.social , who was awarded the prestigious @agu.org Asahiko Taira International Scientific Ocean Drilling Research Prize! www.agu.org/honors/taira

New paper alert! New research from former NAU PhD student Emerson Lynch, SES Prof @rengellia.bsky.social , and colleagues demonstrates that some upper plate faults in the Cascadia subduction zone are very active, with important earthquake hazards implications. Check it out! #nau_geology

NAU SES scientists just finished 11 glorious days of lake coring and glacial geologic mapping around Turquoise Lake in Lake Clark National Park, western Alaska Range. Good weather, hard work, and epic landscapes => an unforgettable field season. #NAU_geology, #NAU_environsci, #NAU_climate

Myself, @kdmorell.bsky.social, @djshillington.bsky.social, and Rob Witter (USGS) used an SSA community grant to host an Alaska Subduction Zone workshop in conjunction with a USGS meeting in January. The community grants are a great option if you're looking to fund a workshop/training. ⚒️

The end of spring semester brings the opportunity to learn about (and celebrate!) the amazing research being undertaken by our grad and undergrad students. MS and PhD defenses! UG research symposium! First year grad student research showcase! Our incredible students are doing incredible things.

🎉Thank you National Science Foundation, for all the #NSFfunded #seismological science you support, including the SAGE and GAGE facilities operated by @earthscope.org. Our current understanding of #earthquakes, #volcanoes and #geodesy research would not be possible without you. ⚒️ 🧪

NSF’s entire Division of Equity for Excellence in STEM (EDU/EES), which “aims to provide opportunities for individuals from all backgrounds to actively participate and excel in STEM disciplines” and some of it congressionally mandated, was just notified they will be RIFed. www.nsf.gov/edu/ees/about

May 1 is NAU's giving day, and we are raising funds for an endowed professorship in Paul Umhoefer's honor. Paul was an amazing scientist, dedicated educator, and remarkable human. If you (like me) were lucky enough to know Paul, please consider making a donation! @nau-ses.bsky.social

The National Academies Committee on Solid Earth Geophysics is hosting a meeting on Marine Geophysics on May 28. We have a great list of speakers/topics, so it should be a great meeting. Join us! www.nationalacademies.org/event/44626_...

AGU has joined a lawsuit challenging the firing of probationary employees at federal agencies. These actions weaken science, harm public health & the environment, and threaten national security. 🧵 #StandWithScience

This is not just horrific, it’s dangerous.

Seniors in NAU a geology field class spent 5 days in the White Hills near Lake Mead for the first of two field trips for their final semester. Much geological mapping was done! #NAU_geology, #SES_students, #DiscoverNAU

We're not cutting fat. We're cutting off limbs. My heart breaks for the federal workers who were fired and for our country that will be SO much worse off without them. And for what? Federal workers make up less of the US workforce in the last ~century. www.washingtonpost.com/business/202...

Federal science agencies are under threat. AGU has made it easy to advocate for NSF, NOAA, NASA and more. Visit AGU’s Science Policy Action Center to stand up for science. fromtheprow.agu.org/standing-tog...

NAU achieves R1 status. Vibrant research programs and a growing doctoral program in SES contributed to that! news.nau.edu/r1-research-...

White House budget proposal could shatter the National Science Foundation - 'The cuts could be as deep as 66 percent, with one person indicating the top-line budget number for the National Science Foundation could start at $3 billion.' vs. $9 billion currently arstechnica.com/science/2025...

Hope reporters are ringing Susan Margulies’ phone off the hook - what information does she have? Whose bidding is she doing?

Fabulous thread by @geophysichick.bsky.social describing what DEI is all about. To do the best science, we need the best people and the broadest range of perspectives!
