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.

With their election to the prestigious honor society, eight members of the Brown University faculty join the nation’s leading scholars in science, public affairs, business, arts and the humanities.
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.

During the 2025 Lunar and Planetary Science Conference, researchers, including DEEPS Professor Jim Head, shared how NASA NIAC-funded technologies could enable building and maintaining surface habitats in lunar lava tubes and dike tip voids for long-term human space exploration.
Rescue teams in Myanmar and Thailand are searching for survivors after Friday’s 7.7 magnitude quake that toppled buildings and damaged roads on Sunday, March 30th. As rescue teams continue to search, experts share the factors that impact their chances for survival. Trapped victims are more likely to survive if they are in a debris-free pocket that prevents major injury while they await rescue, like under a sturdy desk, said Professor Victor Tsai in an email.
NASA’s Curiosity rover has detected what could be a chemical relic of long-ago life on Mars: long-chain organic molecules likely derived from fatty acids, a common building block of cell membranes on Earth. DEEPS Professor Jack Mustard commented on these exciting findings, suggesting that Curiosity’s successor, Perseverance, will likely find similar molecules.
By determining which ice sheets melted to create a colossal increase in sea levels 14,500 years ago, scientists hope to enable better predictions of how current ice melting will affect levels around the world.
In a new article in Nature Review Earth & Environment, Postdoctoral Fellow Lily Dove explores how, with Surface Water and Ocean Topography (SWOT) satellite data, oceanographers are beginning to understand the global distribution of submesoscale currents and their associated vertical motions. This information will inform global and regional-scale climate models, improving predictions of heat and carbon storage in a changing climate.

The Lucy mission aims to study the Jupiter Trojan asteroids, which are considered remnants from the early solar system.
As President Donald Trump’s administration looks to reverse a cornerstone finding that climate change endangers human health and welfare, scientists say they just need to look around because it’s obvious how bad global warming is and how it’s getting worse. “There is no possible world in which greenhouse gases are not a threat to public health,” said IBES Director and DEEPS Professor Kim Cobb. “It’s simple physics coming up against simple physiology and biology, and the limits of our existing infrastructure to protect us against worsening climate-fueled extremes.”
