So how small are the zircons that we date in the lab? Here's a Fish Canyon Tuff zircon on a $5 bill for comparison!

Keep sciencing. We are living through a time when looking at a rock and wondering how old it is qualifies as an act of resistance.

🎂 Happy birthday, #MarieTharp! 🗺️ A pioneering geologist and cartographer, Tharp created some of the world's first maps of the ocean floor, and helped prove the theory of plate tectonics. Her legacy reverberates across ocean sciences today. Learn more: lamont.columbia.edu/news/happy-b...

This Crowned Aeolis (Facelina auriculata) photo is special for more than just its striking blue colors — it's also among the first iNaturalist observations of the species in Canada.

I couldn’t come in person to present my #IAVCEI2025 poster, so here it is for you all to enjoy!
Nine reduced rhyolites erupted in quick succession in the Mono Basin (Eastern California, just north of the Long Valley Caldera) ~6,000 years ago!

Happy birthday to Danish #seismologist Inge Lehmann (1888 – 1993) who demonstrated that the Earth’s core is not a single molten sphere, but contained an inner solid core, in ‘36. She was a pioneer #womanInScience, a brilliant seismologist & lived to be 105. 🧪🐡⚒️ #histsci

This is disrespectful and a flat out lie that further stigmatizes autism. It’s not a virus or a disease - it’s a neurological condition with a wide spectrum. Many Americans with autism work, pay taxes, and are living happy and healthy lives.

A few scenes (with unusually clear sound due to absence of wind) of the Strombolian activity at #Etna's Southeast Crater during the night of 2-3 April 2025. Note the cute little secondary vent in the latter part of the video.

The Pacific Ocean with some granite cliffs in Montara, CA. I hope it brings some momentary peace, like it did for me.

Some examples of research USGS does that is at risk with RIFs and restructuring:
- earth quake and volcano monitoring and warnings
- landslide risk assessments
- water quality testing
- wildlife conservation
- wildfire prevention and post-fire rehabilitation
- invasive species tracking

US volcanoes pose a very real threat to communities and aircraft. Cutting funds will significantly compromise our ability monitor them and mitigate disaster. Why this administration wants us flying blind in volcano territory is an utter mystery. This is not a FAFO situation.

I am not a federal employee, but many of my colleagues are. The work they do to better understand + inform the public on volcanic hazards is deeply important. We are a team. The attacks on education and NSF harms our shared mission. There is no public sector equivalent for the operational work we do
