High temperature geochemist and petrologist @WHOI. Helium isotopes, carbonatites, and ultrahigh-temp metamorphism. Surfskiing, skate skiing, and mountains too.

@ABAInternatl Was this recorded? If so, is the recording accessible for non-ABA members?

Core-mantle geochemical exchange made the Quanta Magazine "Biggest breakthroughs of 2025 in Physics" list. I was flattered to be interviewed for their You Tube feature.

In a new @ScienceAdvances paper, Asst Prof James Dottin shows Hydrogen may leak from the Earth's core into the mantle. "This means that some the the water you're drinking today might be seeing the surface for the first time since the Earth was formed."

Congrats @JonasTheRockGuy for the exciting Geology paper!

Lava flowing from new vent system in this ongoing eruption on #Kilauea's middle East Rift Zone. Lava flowing downslope to brink of Nāpau Crater in channel more than 50 m (about 164 ft) wide, pouring over western cliffs to create lava falls. #HVO overflight video from Sep 19.

Join us for AGU 2024! The IAVCEI Commission on VIPS is sponsoring the session V014:

Magma arising: Tracking Magma Supply from Mantle to Surface at Subduction Zones and Beyond.

Abstract submission deadline is 31st July (23:59 EDT). More information:

@BernieM36010785 Unfortunate! That would be interesting

[Forrest Horton @ForrestHorton]

@BernieM36010785 Measuring 3He/4He?

[Forrest Horton @ForrestHorton]

@magmatist @NSF @SZ4D1 Great picture! In the shape of a subduction zone no less...

[Forrest Horton @ForrestHorton]

@CailCon Awesome!! Congratulations!

@ISS_Research @lunarloral Safe journey!

[Woods Hole Oceanographic Institution (WHOI) @WHOI]

🌋 Rivers of molten lava! Ash so thick it blocks the sun! Chain reaction explosions in the deep sea!

Oh… did we have you at “volcano”? 🤭

Join us #OceanEncounters to learn about the fiery forces brewing deep inside the Earth!

@Astro_Andreas @esa @esaspaceflight @ESA_EO Can you spot the caldera rim of the Yellowstone supervolcano? (Figure from Lowenstern and Hurwitz, 2008)

[Forrest Horton @ForrestHorton]

@Astro_Andreas @esa @esaspaceflight @ESA_EO Nice! Volc. features are best preserved in arid regions where erosion is slowest. Continental volc. fields also exist across the Sahara and SW North America. Iceland-like volcanism occurs on Sao Filipe, La Palma, and Fernandina islands. And Hawaii: Kilauea, Mauna Loa and Kia!

@lunarloral @Space_Station A geology wish list: Ahyi seamount, Marianas (active submarine eruption causing seawater plume); Ol Doinyo Lengai volcano, Tanzania; Vredefort (S Africa) and Lonar (India) impact craters; Clew Bay drumlins, Ireland; Scablands (E Washington) produced by Missoula ice age floods.

@lunarloral Alpenglow on volcanoes!!! Deceptively arid, these volcanoes are unique to ocean worlds with plate tectonics: mineral-bound seawater in the seafloor pulled to depths of ~150 km caused rocks to melt, producing viscous/sticky water-rich magmas that ascended to form stratovolcanoes.

[Forrest Horton @ForrestHorton]

@lunarloral Beautiful braiding! The circuitous path of the Brahmaputra has puzzled scientists for decades. The E-W trending northern portion probably predates the India-Asia collision and was later captured/redirected southward. Remarkably, this river is older than the Himalayas themselves!

@astro_marcus @esa @Space_Station @Astro_Andreas @Thom_astro @astro_matthias @CFuglesang @Axiom_Space @astro_slawosz @Astro_Alex @Raph_Astro @AstroSamantha Depends whether there is an electrical engineer onboard :)

[Forrest Horton @ForrestHorton]

@lunarloral Wow! The most stunning yet!
Image 2 appears to be the Panj River on the Afghanistan-Tajikistan border. The mountains in this area may be especially high because, beneath them, the Asian lithosphere is peeling away and sinking (figure from Chapman et al., 2017, GSAB):
