Scientists Create the First Map of Deep Earthquakes Beneath Continents - Eos Scientists once thought Earth’s continental mantle was too weak for earthquakes. A new global map of 459 deep tremors suggests otherwise.

TIL: CMEs exist in Earth science as well as space science. Not the same CMEs.

What do BLOBs Have to Do with Earth’s Magnetic Field? A Lot, It Turns Out - Eos Enormous provinces of superheated mantle exert a powerful influence over our planet’s magnetic field, researchers have discovered.

Giant BLOBs are pulling the strings of Earth’s magnetic field.

COVID-19 Shutdowns Saw Human Emissions Slow, but Atmospheric Methane Surged - Eos An uptick in wetland emissions, as well as a scarcity of atmospheric OH radicals, contributed to the counterintuitive methane spike.

COVID-19 shutdowns saw global emissions lows, so why did atmospheric methane spike? New research offers an (OH) radical explanation. 🧪 eos.org/articles/cov...

A Long-Term Look Beneath an Antarctic Ice Shelf - Eos More than 4 years of data from a borehole in the Ross Ice Shelf reveal supercooled water and more.

The first long-term hydrographic dataset from under an Antarctic ice shelf reveals supercooled water intrusions, distant polynya influences, and interannual variability in circulation patterns. 🧪 🧊 eos.org/research-spo...

New Evidence Points to Venusian Lava Tubes, and They’re Really Big - Eos Researchers bring new life to 30-year-old Magellan data to unearth the first direct evidence of the long-hypothesized structures.

The skylight to one (probable) lava tube is big enough to fit the entire Eiffel Tower. 🧪

How the Rise of a Salty Blob Led to the Fall of the Last Ice Age - Eos Scientists have long suspected that high salinity levels in the deep ocean were responsible for keeping carbon dioxide locked away during the last ice age. New research finds the strongest evidence…

It’s salty. It’s full of carbon. Its upwelling may have helped end the last ice age. It’s…the salty blob!

Severe 2023 Drought: Sinking Carbon Sink in the Amazon - Eos The Amazon forest has been a reliable carbon sink, soaking up some of humanity’s carbon emissions, but a severe drought in 2023 adds to growing concern that this ecosystem service is at risk.

When the Snow Melts, Microbes Bloom - Eos A new study illuminates a complex and changing world of microbes and nitrogen cycling that occurs during the winter.

New research examines the bloom-and-bust cycle in the earth beneath our feet.

We see them too! 😂

Engineering a Cleaner Way to Extract Lithium - Eos The new chemical solvent technique could cut water use, speed extraction, and unlock reserves like California’s Salton Sea.

Today’s lithium often comes from massive evaporation ponds in arid regions. A new technique instead uses a reusable solvent that could pull lithium from brine faster and with lower environmental impact.

Southern Idaho emerged as the most prolific mantle-quake region in the lower 48 states.

Bacteria Decide the Ocean’s Dissolved Organic Carbon Abundance - Eos Dissolved organic carbon prevalence follows from how many bacteria are around to eat it, modeling suggests.

It’s not what you have, it’s how you use it—even when it comes to the distribution of dissolved organic carbon in the ocean. The type of DOC is less important than how many bacteria are around to eat it, modeling suggests.

Invasive Plants and Climate Change Will Alter Desert Landscapes - Eos In experiments conducted in Biosphere 2, invasive buffelgrass weathers higher temperatures and drought conditions better than its native brethren.

Sea Levels Are Already Higher Than Many Scientists Think, New Study Shows Researchers found that a majority of studies on coastal sea levels underestimated how high water levels are, and hundreds of millions of people are closer to peril than previously thought.

Breaking News: Scientists have been using methods that underestimated how high sea levels already are, a new study found. One result is that hundreds of millions more people are already living dangerously close to the rising ocean than Western scientists had previously estimated.

Senate Committee Approves Bill to Expand NOAA Capabilities - Eos The markup meeting, to discuss the NASA Transition Authorization Act of 2026 and the Weather Research and Forecasting Innovation Reauthorization Act of 2026, lasted less than 20 minutes.

The bill, which Sen. Ted Cruz said “is aimed at improving the accuracy and actionability of forecasts and weather warnings, as well as modernizing weather systems,” will next go to the Senate floor for a full chamber vote.

Nationwide Soil Microbiome Mapping Project Connects Students and Scientists - Eos Researchers and students are building a comprehensive picture of the microbial life beneath our feet.

Ava Hoffman of @fredhutch.org has teamed up with educators, researchers, and students from across the country to create the first-of-its-kind soil microbiome map of the United States.

“Soil is one of the last frontiers on Earth,” she said.

Salt of the Earth: Vast Underground Salt Caverns Are Preserving Our History—and Just Might Power Our Future - Eos From health spas to film storage, salt mine caverns have been put to use in surprising ways—and they’re now poised to contribute to the generation and storage of clean energy.

Former salt mine caverns have all sorts of “salt-ernative” uses these days, from storing movie props to housing clean energy projects.
