Geomagnetism, Paleomagnetism and Electromagnetism

Members of the Geomagnetism, Paleomagnetism and Electromagnetism Section study the magnetic field, from Earth's core to other planets and to outer space, to gain an understanding of Earth's structure, dynamics, and history and its relationship to other planets... Read More

#Microplastics found up where they don’t belong—in the Italian Alps. (from last week's #EGU19 meeting)

Book review: "Combining economics, character studies, a history of the aquarist hobby culture, biology and ecology with a good dose of adventure travel, I found The Dragon Behind the Glass to be an enjoyable read."

“Mercury’s interior has cooled more rapidly than our planet’s. #Mercury may help us predict how Earth’s #magnetic field will change as the core cools.”

About 11k years ago, the Sahara was once green. But what happened to us when it dried up? Well, we moved. Far. In our latest @ThirdPod #AGU100 episode, @leafwax of @UofA told us about how #climate affected human migration. https://t.co/rKenTvEJNh @theAGU #SciComm #podcast

Some “what-if” climate modeling from #EGU19: What would happen if we diverted all available water on land—every river, every lake—and used it for irrigation?

“What we found was that Maria’s magnitude of peak precipitation is much more likely in the climate of 2017 when it happened versus the beginning of the record in 1950.”

Meier et al. (2019): “We can successfully train complex deep learning classifiers that can discriminate between nuisance and #earthquake signals very reliably (accuracy of 99.5%).” #machinelearning #AGUPubs #JGRSolidEarth https://t.co/DK70eMbbMx

Research Spotlight: Why did some of the #Moon’s craters form into multiple concentric rings?

A 2017 executive order mandated a plan to evaluate U.S. access to critical mineral resources, but the airborne magnetic survey maps that support this effort are sadly out of date.

Broderick et al. (2019): “River catchments have very different physical attributes that affect their sensitivity to change. We develop a framework that groups catchments based on their physical characteristics into distinct sensitivity types.” #AGUPubs https://t.co/T6rgQ6kF5V

Between 1961 and 2016, glaciers lost more than 9,000 billion tons of ice. “That’s a very big number equivalent to an ice cube the size of Germany over 30 meters thick.”

Book review: "The Feather Thief is an interesting read...it’s one of those nonfiction books where the narrator starts off as a dispassionate reporter but becomes more and more involved in the story he’s reporting."
