Hydrothermal Heat Flow as a Window into Subsurface Arc Magmas
What can warm fluids in arc crust tell us about how much magma is lurking underground? Hydrothermal heat fluxes provide constraints on the supply of magma from the mantle in subduction zones.
Widening Channels and Westerly Winds Together Formed Earth’s Strongest Current
The Antarctic Circumpolar Current could only develop once wind patterns aligned with new ocean passages 34 million years ago, a new study suggests.
Hurricane Helene Ravaged Farmers’ Topsoil. They’re Still Fighting to Build It Back.
“We’re dirt farmers. Our primary job is to tend the dirt. That’s the basis of everything.”
Location, Location, Location: The “Where” of Reforestation May Matter More Than the Extent
A new study finds that focusing reforestation efforts in strategic locations, such as the tropics, can accomplish global cooling levels comparable to less strategic reforestation efforts covering twice as much area.
What’s Below the Great Salt Lake? More Water
Pools of fresh water and salt water not far below the lake bed help explain some of the lake’s curious features, including mineral mounds and reed islands.
Choice of Glen’s n Leads to Differing Projections of Ice Sheet Mass Loss
Glen’s Law describes the simple physics of ice flow that underpins ice sheet models, but parameter choices substantially influence the outcome of model projections.
Navigating the Past with Ancient Stone Compass Needles
The emerging field of magnetic microscopy allows scientists to reconstruct ancient magnetic fields from individual magnetic particles. A new study evaluates the accuracy of the technique.
Cleanup of Battery Recycling Sites May Lower Childhood Lead Exposure
Unsound recycling of lead-acid batteries pollutes the soil around houses and agriculture fields in developing countries. Soil remediation might help in lowering the blood lead levels of children.
Glaciers May Flow into the Ocean More Quickly Than We Think
New research found that adjusting a key model variable may give more accurate predictions of glacial retreat.
On the Seattle Fault, the Biggest Quakes Aren’t the Most Likely
Smaller quakes from secondary faults—which are not included in national seismic hazard modeling—occur more frequently than previously thought.
