This new work combines experimental petrology and modeling to understand the conditions of sedimentary diapir formation occurring in subduction zones. Led by collaborators at University of Arizona along with DEEPS Assistant Professor Emily Cooperdock, the authors find that subducted sediments are unlikely to form diapirs except in warm, slow subducting systems. Sedimentary diapirs may contribute to arc magmatic geochemical signatures under these specific conditions.

DEEPS PhD candidate Hannah Shabtian and Professor Greg Hirth have published a new paper in Geophysics Research Letters. "The paper describes novel characterization of talc rheology and some cool applications of our flow law for understanding strength of earth's crust in subduction zones," Shabtian shared.

DEEPS Chair, Professor Meredith Hastings discussed the air quality in Providence, as monitored through her Breathe Providence project.

Last week, DEEPS scientists came together for the Department Poster Session! This annual event allows students, postdocs, faculty, and research groups to introduce their recent work, explore the wide variety of research happening in the department, and meet new additions to the the DEEPS community.

Assistant Professor Daniel Ibarra is co-author of this study, which provides a new framework for examining how organisms have fundamentally altered ecosystems on a global scale across hundreds, thousands, or millions of years.

Assistant Professor Mara Freilich is co-editor on a new book, "Climate Changed: Models and the Built World," available now through Colombia University Press. The book examines models and their imperfect yet central role in understanding the relationship between global climate dynamics and the human-built environment. It compares and synthesizes the methods and function of models in disciplines ranging from architecture and planning to climate science and natural hazards research.

New research offer clues to Mars’s history, including what violent collisions it experienced in the past and how it lost its magnetic field. Professor Ingrid Daubar, former member of the InSight science team, commented on these recent studies, saying, “There are connections to our own planet, to how planets form in general and to how we understand different planets outside our solar system.”

DEEPS PhD student Alejandra López contributes to two new briefs revealing widespread nutrient pollution, dangerously low oxygen levels in the lake, and frequent episodes of hydrogen sulfide emissions that exceed California’s health standards—conditions occurring among residents in areas that rank among the most burdened by pollution in the state. López noted, “Families live with chronic exposure to pollutants that would never be tolerated elsewhere. We call for enforceable standards and local-focused solutions that put residents at the center of restoration.”

A new publication in G3 led by Assistant Professor Emily H. G. Cooperdock untangles the systematics of uranium enrichment for serpentinites from different tectonic settings and explores potential mineral hosts. The researchers found that "uranium enrichment is most common in the upper 100m of the seafloor and is not correlated with degree of serpentinization. We also find a correlation between U concentration and iron-oxidation, which we use to suggest that U is hosted in ferric iron minerals, possibly iron-oxides." The paper also provides insights on using uranium as a tracer for tectonic setting, fluid rock interactions, and redox records in the solid Earth system.

More than 85 climate scientists declared the Department of Energy’s new climate report unfit for policymaking in a comprehensive review. DEEPS Professor and IBES Director Kim Cobb, who co-authored two sections of the review, said, “It’s really important that we stand up for the integrity of [climate science] when it matters the most. And this may very well be when it mattered the most.”

DEEPS Postdoctoral Research Associate Nick Wagner recently published a new paper in JGR: Planets. "In this study, we update our understanding of how magma trapped inside a planet influences gravity and the shape of the surface by considering their volumetric effects, and we revise the estimates of the proportion of volcanic material that erupted versus material that did not. Our results, which use geophysical data and methods, align closer with findings from other lines of evidence. This suggests that the ability of magma to erupt in the Tharsis region has increased over time, pointing to a longer period of volcanic activity than previously believed."

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.
