Many researchers describe public outreach as a labour of love, often carried out in their spare time. But some funders reward these activities. In an interview with Nature, Voss Postdoctoral Research Associate Lina Pérez-Angel described her insight and experience with science communication, noting “Science communication is as real and as hard as doing research.”

2024 Summer Undergraduate Research Highlights

From missions to the Moon & Mars, to lake sediments, to climate modeling, many undergraduate students worked on groundbreaking research in DEEPS this summer break. This year, we are excited to showcase these diverse research projects through a special combination of art, writing, and photography developed by Claire Xu ‘27.

In a recent study published in the PLanetary Science Journal, researchers describe an odd surface feature that supports the presence of underground caves termed subsurface voids. DEEPS professor and study co-author James Head indicated that the relatively low lunar gravity likely allowed big bubbles of gas to form in magma, leaving behind subsurface voids.

In a recent study published in Science Advances, DEEPS PhD candidate Manar Al Asad and Assistant Professor Harriet Lau demonstrate that Earth's early tectonic activity was likely very different from what we see today. They propose a 'sluggish-lid' mode, where the Earth's outer layer moved slowly and was partially disconnected from the mantle. The new model addresses previous challenges in understanding Earth's thermal history and tectonic evolution, offering new insights into how Earth's magnetic field is maintained throughout most of Earth's history.

Since last July, Earth’s average temperature has been at least 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial levels. IBES Director and DEEPS Professor Kim Cobb spoke with the Washington Post about this trend, saying “We’re dancing about a climate average that is very dangerous for communities and ecosystems around the world.” Read more.

Postdoc Lily Dove explains how seals have become valuable allies with scientists who are studying how the oceans are changing in the remote reaches of the Southern Ocean. Tags on the seals' heads collects data while the seal dives and transmits its location and the scientific data back to researchers via satellite when the seal surfaces for air.

Rhode Island Superior Court Associate Justice Brian Stern has issued a temporary restraining order after a fire at Rhode Island Recycled Metals LLC. The fire released smoke and potentially harmful chemicals detected throughout the city and into Pawtucket by Breathe Providence sensors, according to expert testimony from Meredith Hastings, DEEPS Chair and project lead for Breathe Providence.

New research shows that, rather than an opening of the passage, the safe shipping season declined along several “choke points” through the Canadian Arctic, especially on the northern route. The finding matches expectations that ice will survive longest in the Canadian Arctic, noted DEEPS Professor Amanda Lynch, who was not involved with the study.

Assistant Professor Dan Ibarra and his team have published a special outreach article in in PAGES Horizons highlighting their cave monitoring efforts in the Philippines. Ibarra said, "it is exciting to share our efforts to develop this work in multiple cave systems in the Philippines over the last several years." The work is led by former Voss Postdoc Natasha Sekhon, co-authored by Celia Kong-Johnson, Justin Custado, Carlos CP David, Mónica Geraldes Vega, and many others, and made possible with support from the National Cave and Karst Research Institute and the Institute at Brown for Environment and Society (IBES).

LUMIO – New CubeSat Illuminating Lunar Impacts

LUMIO is a newly approved CubeSat mission to observe meteoroid impacts on the lunar farside. This week, the ESA approved the next stage of the Lunar Meteoroid Impacts Observer (LUMIO) CubeSat mission, meaning it could be ready for launch as early as 2027. In 2023, Postdoctoral Research Associate Aleksandra Sokołowska was selected to be a member of the LUMIO Science Team. She shared her excitement for the project, saying "Being a part of this mission in its early stages has been incredibly fun and rewarding because members of our Science Team come from many different countries, work collaboratively, and the areas of expertise are very diverse. This final mission approval means that the journey continues."
