Thank you to everyone who attended our EAPS Annual End-of-Year Picnic! We had a beautiful evening with great food, hacky sacking, and a visit from a porcupine! Congratulations to all of the 25-26 EARS department award winners, and congratulations to all on completing this academic year!

Yesterday was the Earth & Planetary Science 2026 Senior Honor Thesis Presentations, where twelve of our EAPS undergrads presented the culmination of the research studies they have completed this year. Special thanks to Leslie Sonder, the EAPS Undergraduate Advisor, for hosting this evening!

Associate Professor of EAPS Justin Strauss was recently quoted in Earth.com: “Given our understanding of the regional geology in northwestern Canada, there is great potential here to revisit our understanding of Ediacaran Earth history,”. See the article here: www.earth.com/news/canadia...

As of this summer, @dartmouthears.bsky.social will be known as the Department of Earth and Planetary Sciences. “We’ve been building toward this for about 20 years, and the research has genuinely grown to span both Earth and other planetary bodies,” says department chair Meredith Kelly.

.@dartmouthears.bsky.social professor Robert Hawley was named director of the Dartmouth Center for the Advancement of Learning, which enriches teaching and learning on campus through programs and resources for anyone engaged in teaching at #Dartmouth.

"There is great potential here to revisit our understanding of Ediacaran Earth history.” @dartmouthears.bsky.social professor Justin Strauss co-led a study that found a diverse deposit of Ediacaran fossils in Northwestern Canada, suggesting complex animals evolved earlier than previously understood.

Today many of our EAPS undergrads presented their work at the Wetterhahn Science Symposium. Notably, two of our undergrads won 2nd & 3rd place for their Senior Honors Theses! Congratulations to Caleb Saks and Jacob Schnell! Read more on the Wetterhahn here: students.dartmouth.edu/surfd/news-e...

This term, EAPS undergraduate ‘Ale’aokalani Kahele (‘27) has worked on a project to create a guide for future Stretchies detailing the history of the different tribal lands the EAPS off-campus field program, ‘The Stretch’, goes through and more! See more here: alea-stretch-seven.vercel.app

Students in the field! Students in the EARS 1 intro lab course spent the afternoon learning how to gauge the stream velocity of Mink Brook in Etna, NH by measuring stream transect, depth, and velocity from Dr. Justin Stroup.

Please join us in congratulating C. Brenhin Keller who has been promoted to the rank of Associate Professor with tenure! Read more about Brenhin’s work here: brenhinkeller.github.io

A New Name for Earth Sciences! Starting this summer, Dartmouth’s Department of Earth Sciences will be known as the Department of Earth and Planetary Sciences (EAPS). Dartmouth’s growing research program in planetary science will now have a name to match! Read more: fas.dartmouth.edu/news/2026/05...

Congratulations to Professor of Earth Sciences Robert (Bob) Hawley, who has been named director of the Dartmouth Center for the Advancement of Learning, effective July 1! As Bob says “Teaching and learning are, by their very nature, a human interaction”. home.dartmouth.edu/news/2026/05...

Congratulations, Dr. Joel Wilner, on a successful PhD defense! Joel’s dissertation is titled “Pushing the Boundary: Modeling and Data-Driven Insights into Paleoclimate and Erosion at Glacial Margins”

Congratulations, Lauren Morrison, on a successful Master’s defense! Lauren’s thesis is titled “Investigating the preservation of goethite through magnetic techniques”.

Congratulations, Dr. Jiawen Li, on a successful PhD defense! Jiawen’s dissertation is titled “Tracing Microbial Methanogenesis and Methane Oxidation with Clumped Isotopologue Compositions of Methane”

Jacob Chalif, a graduate student in EAPS, was featured in an article commenting on his recently published study showing that "waviness" in the polar jet stream that brings Arctic-like conditions farther south are not historically uncommon. Read more at www.climate.us/news-and-fea...

Congratulations to EAPS Assistant Professor Sarah Slotznick for receiving the Department of Energy Early Career Research Program Award for 2025! The prestigious award provides long-term support for the research of outstanding early-career scientists. See more at: fas.dartmouth.edu/news/2026/01...

"The biggest (misconception) in general is people think that the mantle is made of magma, or the mantle is molten or liquid.” Earth sciences professor @brenhinkeller.bsky.social discusses misunderstandings about the Earth’s structure with Indy100.

Huge thanks to Don Perovich, Chris Polashenski, Cameron Planck, and others for leading and maintaining CRREL, Dartmouth @dartmouthears.bsky.social, and Cryosphere Innovation www.cryosphereinnovation.com ice mass balance buoy programs.

With some much terrible news, I want to share something positive. This is a spodosol my students made for our soils class back @dartmouthears.bsky.social featuring O-reo horizon, whipped cream E horizon, pudding Bhs and B horizon, and graham cracker glacial till.

Ever felt the ground tremble, creak, or groan? It turns out that small earthquakes in New Hampshire are somewhat common, according to @dartmouthears.bsky.social professor Leslie Sonder, via NHPR ⤵️

The people have a right to climate data. Outstanding op-ed by Justin Mankin. Couldn't have said it better, agree with everything. www.nytimes.com/2024/01/20/o...

Although it happened two weeks ago, wanted to post how great it was to see Josie successfully pass her MSc defense! (First graduate student and first post 😄)

A review in the Washington Post says that Dartmouth professor Darrin McMahon offers a "wide-ranging history" in his new book that "demonstrates that progress toward achieving equality is almost never linear." ⤵️

New research co-led led by Dartmouth anthropologist Nathaniel Dominy suggests that the eyes of Rudolph and his reindeer brethren may have evolved so that they can spot their favorite food during dark Arctic winters, via @BBC. ⤵️ 🎅

Let's talk about Ernest Everett Just, a cell biologist who unraveled the mysteries of fertilization in spite of the obstacles he faced as an African-American. Just's story weaves together good, rigorous science with racism & tragedy. He was born in 1883 in seaside Charleston, South Carolina.

This is a great fellowship for anyone looking to do a computationally-minded postdoc at Dartmouth, with any faculty in any department (including Earth Sciences)!

Really enjoying watching the new PBS NOVA series "Ancient Earth" featuring these awesome Bsky superstars 🌟🤩 @phoebefossil.bsky.social @brenhinkeller.bsky.social @seismatters.bsky.social @egmitchell.bsky.social @wgbh.org

The other thing I wish I could tell everyone is that the machine learning is more specifically a parallel Bayesian inversion via MCMC (Metropolis modified with a form of "parallel tempering"), but that's trickier to explain so I'm worried folks are assuming we're using neural nets or something silly

Yeah, we're effectively blind to an impact winter (as are most proxies) -- but importantly not to the CO2 or SO2 that would have been emitted by the impact (CO2 sticking around for many time bins and SO2 falling out of atmosphere but going on to influence ocean alkalinity which is included in model)

Nice write up on the machine learning paper on the end-Cretaceous mass extinction (Deccan Traps CO2 & SO2 explain climate proxy data) with independent comments from (count them) 3 geochronologists: Renne, Sprain, Kasbohm! 🌋☄️ ⚒️🧪 www.wired.com/story/what-k...

If you like the K-Pg boundary and/or Bayesian inversions, check out this paper out today in Science by my @dartmouthears.bsky.social MS student Alex Cox!! www.science.org/doi/full/10....
