Featured Research
Mars has a mini-magnetosphere
A mini-magnetosphere, similar to the one found on Venus, has been observed above Mars by NASA’s MAVEN mission. Unlike Venus, whose magnetosphere is solely generated from the clashing of solar wind particles against the planet’s ionosphere, Mars also possesses inherent magnetic fields near its crustal surface that shield parts of the planet from solar winds. This combination of intrinsic and induced properties makes Martian solar defenses unique to the Solar System.

The Amazon is getting drier
The southern Amazon is getting drier, decreasing its ecological health and ability to balance global hydrological and energy cycles. The trend will likely continue, a new study finds, as 2040-2070 is expected to be about 20% drier than the recent historical period. [JGR Atmospheres research]
California regions prone to clusters of atmospheric rivers
Atmospheric rivers, or long narrow regions that transport water vapor, can arrive one after the other, in clusters and with compounding negative effects. While both the Pacific Northwest and California experience atmospheric rivers, mountainous regions in California tend to get more clusters that also last longer, a new study finds.

How crabs engineer salt marshes
When fiddler crabs burrow, they create tunnels that speed up groundwater and salt circulation, promoting the export of carbon and nitrogen from salt marshes to the ocean. This process, which is vital for healthy plant production, can vary based on the shape of the burrows and the number of entrances that are dug, a new study finds.

Some high-threat volcanoes are severely understudied
Scientists have little understanding of where magma is stored along the Cascade Volcanic Arc or how its volcanoes could affect population centers. [Geochemistry, Geophysics, Geosystems research] [Eos Research Spotlight]
AGU (www.agu.org) is a global community supporting more than half a million advocates and professionals in Earth and space sciences. Through broad and inclusive partnerships, AGU aims to advance discovery and solution science that accelerate knowledge and create solutions that are ethical, unbiased and respectful of communities and their values. Our programs include serving as a scholarly publisher, convening virtual and in-person events and providing career support. We live our values in everything we do, such as our net zero energy renovated building in Washington, D.C. and our Ethics and Equity Center, which fosters a diverse and inclusive geoscience community to ensure responsible conduct.
