Continuing Public Health and Environmental Crisis at the Salton Sea Amid Gaps in Oversight

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.”

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.”

Uranium Addition and Loss in Serpentinites: The Potential Role of Iron Oxides

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."

How the Earth's Rhythms Keep Time

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.

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?”

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."

In a new study published in Icarus, a team of researchers led by DEEPS graduate student Thomas Williams and Professors Stephen Parman and Alberto Saal have used modern analysis techniques to closely examine the microscopic mineral deposits on the outside of lunar beads from the Apollo mission. The team's findings suggest a change in eruption style over the course of a pyroclastic volcanic eruption in the Taurus-Littrow Valley.
