From freshly formed simple craters on the Moon to hydrogen sulfide production in the Salton Sea, DEEPS undergraduate students participated in cutting edge research throughout the 2025 summer break. We are proud to showcase some of these research projects with this photo series.

DEEPS Assistant Professor Harriet Lau recently presented at TEDx New England on the our planet's natural cycles and rhythms – from micrometers to thousands of miles, and from milliseconds to millions of years. Throughout Earth's multi-billion-year history, these rhythms collide, interact, and unfold, influencing humanity and shaping our experience of time.

ecoRI News spoke with experts about the risks that Rhode Island will face going forward as heat waves hit more frequently and for longer periods. DEEPS Chair Meredith Hastings commented, noting that when it’s hot outside, air quality tends to get worse. “Under hotter conditions we speed up reactions,” she said. “That can lead to the faster production of secondary pollution.”

Dozens of veteran climate scientists have launched a coordinated response to a Trump administration report that casts doubt on the severity of climate change. Kim Cobb, DEEPS Professor and Director of IBES, told CNN it’s significant that the Trump administration is deep-sixing the climate assessments at the same time it’s releasing a misleading new report. She also said she hopes to help “set the record straight” on climate science in their response to the DOE report.

A new art installation on Public Street by artist Eli Nixon features colorful windsocks that are raised as local air quality fluctuates. DEEPS Chair Meredith Hastings attended the windsock event and spoke about air quality issues, which she has studied as a part of her project Breathe Providence.

Strong new evidence suggests that primordial material from the planet’s center is somehow making its way out. Continent-size entities anchored to the core-mantle boundary might be involved. Assistant Professor Harriet Lau commented on this exciting research, noting: if material is effusing from the core into the mantle, is the boundary between them “as distinct as we think?”

Turn To 10's Mario Hilario speaks with Logan Tullai, Artist-in-Residence at the Knight Memorial Library in partnership with LunaSCOPE and the NASA Rhode Island Space Grant, about the art project he's spearheading that gets the community involved by using the sun to print pictures of the moon.

This article in Nature investigates how researchers are filing appeals, seeking court remedies, turning to philanthropy and starting GoFundMe campaigns to support their research. The article includes the cancellation of Assistant Professor Mara Freilich's NASA grant, which engaged citizens in studying the air quality around California's Salton Sea.

New research is using tracks from dust devils to learn about the whirlwinds and potentially guide future mission planning. "Dust devils themselves are difficult to capture in images because they are so short-lived," said Associate Professor Ingrid Daubar, lead author of the study. "The tracks they leave behind last longer, so we are able to observe them more thoroughly."

During the European Astrobiology Institute’s BEACON 25 conference in Reykjavik, Postdoctoral Fellow Adam Valantinas spoke with Forbes about NASA’s Perseverance rover and its ongoing exploration beyond Jezero Crater’s rim.

Their geologic journey included the grandeur of Zion National Park, the unique hoodoos of Bryce Canyon National Park, the enigmatic splendor of Escalante Petrified Forest, and much more. Enjoy these photos from their exciting and educational adventure!

Assistant Professor Mara Freilich is one of the seventeen researchers on cross-disciplinary teams to win funding in the first year of "Scialog: Neurobiology and Changing Ecosystems", a three-year initiative that aims to spark new science exploring neurobiological response to rapid and extensive human-caused environmental changes. Freilich and her team will be exploring "From Feeding to Flux: Unraveling the Impact of Animal Behavior on Global Ocean Carbon Flow."

Improving water systems is a key way we can better adapt to climate change, according to Brown oceanographer Baylor Fox-Kemper.

Conversations about sea-level rise often spotlight warming temperatures. But Earth’s geological engine quietly plays its own role. Professor Colleen Dalton, together with colleagues, connects the dramatic change in sea levels to a slowdown in seafloor spreading that reshaped the depth of the ocean basins.

Every year, distinguished Brown scholars are nominated for Research Achievement Awards by their colleagues for conducting exceptional and transformative research. Assistant Professor Daniel E. Ibarra was named one of the The 2025 Early Career Research Achievement Award winners for his significant contributions to geochemistry, paleoclimate studies, natural resources, and the training of aspiring scientists.

In a new Science Advances publication, Assistant Professor James Dottin III demonstrates how Hydrogen may leak from the core into the lowermost mantle, become entrained in mantle plumes, and mix into the upper mantle. "We typically think about the water cycle on the surface," explained Dottin, "but we often don't consider what happens to water beneath our feet through deep Earth processes." By measuring 2H/1H ratios in olivine-hosted basaltic melt inclusions from a Baffin Island lava, Dottin and his team investigated whether mantle plumes contain Hydrogen from the core. "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."

Swathes of scientific data deletions are sweeping across US government websites, and scientists are racing to save their work before it's lost. "Climate science is only possible because of long-term datasets," says DEEPS Postdoc Lilian Dove, a US Noaa climate and global change research fellow. "Without continuing to collect that data, preserve that data, our field is in really big trouble."

Dr. Bethany Ehlmann, a 2010 graduate of Brown with with a PhD and MS in geology, has been named director of the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder. LASP’s mission is to advance scientific discovery and inspire the next generation through forefront research, innovation and education.

Maggie Gonzalez, a 2025 Leadership Alliance REU student, has published a paper in Geophysical Research Letters with DEEPS Postdoc Lily Dove and Assistant Professor Mara Freilich. The publication explores the biogeochemical and seasonal properties of Antarctic Winter Water using data collected by profiling floats. Gonzalez developed an algorithm to detect a layer of water in the Southern Ocean from observations, as well as the first description of the seasonal and geographical patterns of the biogeochemistry of this water.
