The Odyssey orbiter captured clouds and dust in the Red Planet’s skies, along with one of its two tiny moons. Laura Kerber '11, deputy project scientist for NASA’s Mars Odyssey orbiter, explains in a video how and why the spacecraft captured a view of the Red Planet similar to the International Space Station’s view of Earth.

Navigating a New Arctic

“There’s no scenario in which melting ice in the Arctic is good news,” said DEEPS Professor Amanda Lynch, the lead author on a 2022 study in the Proceedings of the National Academy of Sciences. “But the unfortunate reality is that the ice is already retreating, these routes are opening up, and we need to start thinking critically about the legal, environmental, and geopolitical implications.”

The Community Noise Lab and Swearer Center at Brown University organized a forum titled, "Firing Back" held on November 13 at the School of Public Health. At the event, Juliet Fang, a second-year undergraduate student at Brown studying Public Health and Geology-Biology, shared data indicating that the noise levels from the firing range were higher than what the city of Cranston legally allows. Her study underscored the link between noise pollution and various health issues, including disrupted sleep, heightened stress, and cognitive impairments, as well as chronic conditions like hypertension and heart disease.

The last 12 months were the hottest Earth has ever recorded, according to a new report by Climate Central, a nonprofit science research group. IBES Director and DEEPS Professor Kim Cobb commented that the heat of the last year, intense as it was, is tempered because the oceans have been absorbing the majority of the excess heat related to climate change, but they are reaching their limit. “Oceans are really the thermostat of our planet ... they are tied to our economy, food sources, and coastal infrastructure.”

DEEPS & IBES Professor Meredith Hastings is a co-PI on a new project that will center on a field safety, anti-harassment, and bystander intervention training certificate program. “In scientific work, hostile behaviors such as bullying and harassment create a negative work environment that is more often experienced by people of color and those with disabilities. This is an important reason why the geosciences remain one of the least diverse STEM fields,” said Hastings.

The Rhode Island Department of Environmental Justice has released a new environmental justice policy to prioritize racial and socioeconomic fairness in its agency practices. Professor Meredith Hastings commented, saying she listened to input from community members when deciding where exactly to put the air monitors for her research. “More needs to be done to better understand what residents are exposed to, what sources/industries are responsible and our regulatory system needs to move beyond simply expecting industry to comply by making it harder for these businesses to cause harm in the first place,” Hastings wrote to The Public's Radio.

Uranium isotopes as tracers of serpentinite weathering

Assistant Professor Emily Cooperdock and colleagues have published new research on uranium isotopes in serpentinite rocks found both underwater and on land. The team discovered that the uranium isotope ratios in submarine serpentinites are influenced by seafloor weathering and differ from seawater ratios. Overall, the results show exciting evidence that U-isotopes can be used to measure recent weathering of ultramafic serpentinites. The findings also caution against using these systems as indicators of ancient geological events.

Researchers used temperature and humidity data along with climate models to analyze humanity’s exposure to potentially lethal heat as the world warms. IBES Director and DEEPS Professor Kim Cobb said the study’s conclusions are “compelling” but not surprising. “Extreme heat is already responsible for countless deaths worldwide every year,” Cobb told CNN.
