DEEPS is proud to announce that Department Chair and George Ide Chase Professor of Physical Sciences Meredith Hastings is this year's recipient of the Meenakshi Narain Excellence in Research Mentoring (ERM) Award.

In this new study, DEEPS graduate student Manuel Justin Custado examines the authorship of climate science research in South East Asia, offering a valuable lens into who is funding, writing, and accessing climate science for this highly impacted region. "Quantifying these patterns can provide insights into key challenges and opportunities regarding the participation of local researchers in SEA climate science."

DEEPS Professor Victor Tsai spoke with NPR's Short Wave podcast about "lake stars," the dark spidery, star-shaped patterns that can form in ice, and how he became the first person to scientifically prove how they form. Plus, he explains how knowing more about lake stars can potentially give us clues about the presence of water on Europa, one of Jupiter's icy moons.

Three DEEPS graduate students have created a Field Preparedness Guide, a fillable brochure and informative guide to help support safe, productive, and fun field experiences for undergraduate and graduate students.

In this video, DEEPS Chair Meredith Hastings (George Ide Chase Professor of Physical Sciences and Professor of Environment and Society), and Jesus Holguin, Executive Director and Programming Steward of the Racial & Environmental Justice Committee in Providence, speak powerfully to their experience building a research collaboration grounded in shared power and ownership, trusting relationships, and knowledge held by communities as well as academics.

A blend of chemistry and molecular-biology techniques are enabling archaeologists to mine ancient sediments for clues about the people who once lived there. DEEPS Professor James Russell commented on how ancient vegetation can provide reveal hints about ancient climate: the heavier it rains in the region, “there’s less and less of the heavy isotope left and more and more of the light isotope.”

A recent study utilizes ancient plant waxes preserved in sediments from two Utah lakes to investigate ancient climate history. Assistant Professor Dan Ibarra noted that a key reason for analyzing the hydrogen isotopes is to compare the climate patterns revealed by the plant wax to the patterns predicted by current climate models.

Professor Jim Head is heading the 500-Day Design Reference Mission, which researches practices that would be necessary for 500 days on the moon. The project also helps to train the next generation of planetary scientists. WaTae Mickey ’26, a research assistant in Head’s lab, is researching the site where Apollo 15 landed. Logan Ramanathan ’28, another research assistant in the lab, is researching lunar surface power and surface interactions with rocket exhaust.

The Brown Daily Herald spoke to weather experts, including Professor Amanda Lynch and graduate student Maria Luìsa Rocha, to understand the distinction between the two winter weather events. “In short, all blizzards are snowstorms, but not all snowstorms meet the criteria to be classified as blizzards,” Maria noted.

A new study led by DEEPS Assistant Professor Emily H. G. Cooperdock and DEEPS 2024 REU alumn Ailani Bonilla investigates how nitrogen is stored in ultramafic (mantle) rocks from subduction zones. Their study tested whether serpentine, talc, or chlorite store most of the nitrogen in fluid-altered mantle rocks rocks, as has been proposed by previous researchers based on their sheet-like crystal structures. They found that while these minerals contain some nitrogen, they do not host the majority of it, indicating that a substantial portion resides in other minerals or sites within the rocks. This finding has important implications for models of nitrogen mobility and storage during subduction, metamorphism, and fluid-rock interactions.

A historic 37.9 inches of snow fell in Providence this week, breaking the record as the snowstorm is the largest recorded in state history. DEEPS Associate Professor Jung-Eun Lee shared insight into what causes blizzards, and what factors contributed to this historic weather event.

In an interview with The Boston Globe, Professor James Head discusses his experiences working with NASA to help land Apollo astronauts on the moon, compared with helping today's 18 astronauts selected for the Artemis mission. "The big thrill for me now is not so much doing it again, it’s that we get to share it with people who didn’t get the individual experience before," Head noted. "I think there’s hope that it’s going to be as inspirational as Apollo 8 was. ... I want my students who are now working at NASA headquarters to have the thrill of all this."

Olivia Anderson shares her scientific journey in the geosciences in this spotlight interview by DEEPS Communications Assistant, Hania Khan.

DEEPS Assistant Professor Dan Ibarra and Postdoc Gavin Piccione are co-leaders on a collaborative research project funded by the National Science Foundation to examine how climate behaved in past climates when large lakes existed in the Mojave Desert.

Postdoctoral Research Associate Andrea Rajšić and Research Scientist Matt Jones have each been awarded funding through NASA's Lunar Data Analysis Program (LDAP) for their projects: "Moon Underground" and "Re-investigating the Moon’s Crustal thickness."

In honor of International Day of Women and Girls in Science and Black History Month, Data Scientist Matt Jones highlighted some pioneering scientists whose legacies are especially important to the researchers and students here in DEEPS.

When DEEPS postdoctoral geochemist Gavin Piccione received a notification of possible lead pollution in his area, it inspired the development of the Urban Water Pollution Project (UWPP), a collaborative research initiative to understand heavy metal pollution in the Moshassuck and Woonasquatucket watersheds in Providence. “The goal and the strategy is the more you know, the more power and more connection to this place you have,” Piccione said.

In a recent perspective paper, Assistant Professor Mara Freilich, former posdoc Lilly Dove, and graduate student Katarina Merk present observational and model-based evidence for ocean eddy processes that lead to small-scale heterogeneity in the upper mesopelagic ocean.

Professor Baylor Fox-Kemper recently offered commentary on the clean-energy economy and climate change. “The transition toward a clean energy economy is well underway, and that’s happening all around the world,” Fox-Kemper said.

DEEPS PhD student Peter Van Kawtyk, with co-authors Professor Baylor Fox-Kemper, Assistant Professor Karianne Bergen, and Dr. Helene Hewitt (UK Met Office), have published a new perspective paper that discusses emerging research on machine learning-based "emulators" in climate science. They argue that "the next phase of climate modeling hinges on closer collaboration between simulator and emulator communities."

Dr. Rocío Paola Caballero-Gill, a 2015 PhD graduate, was recently presented with the 2025 Randolph W. “Bill” and Cecile T. Bromery Award. She is a pioneering advocate for the Latinx community, disabled scientists, and all minoritized groups in STEM. Her work has made innovative and impactful contributions both to paleoclimate research and to the creation of community-engaged initiatives that broaden participation in the geosciences.

NASA’s Artemis II mission will be taking astronauts Reid Wiseman, Victor Glover and Christina Koch as well as the Canadian Space Agency’s Jeremy Hansen to the vicinity of the moon for the first time since Apollo 17 in 1972. DEEPS Professor commented on the mission's parallels with the Apollo 8 mission, noting, "Here are these four brave astronauts making observations of the moon and looking back at the Earth after over 50 years. It’s going to be new. With all the confusion that’s going on on Earth today, it could even be a force for bringing people together..."
