A New Tool May Make Geological Microscopy Data More Accessible
PiAutoStage can automatically digitize and send microscope samples to students and researchers on the cheap and from a distance.
Tracking Excess Nitrogen with Freshwater Mussels
Mussel shell periostracum and carbonate bound organic matter document seasonal variability in the isotopic composition of riverine suspended particulate organic matter.
Taking the Temperature of Antarctica’s Crust
How do you measure the geothermal heat flux in a continent covered by an ice-sheet? A new study uses correlations of diverse global observables and produces a heat flow map of the entire Antarctica.
Insights from the Depths of Hawaii’s Kīlauea Volcano
One of the world’s best monitored and most active volcanos still has secrets to yield, and researchers are turning to vapor bubbles trapped in melt inclusions to find them.
Measuring Massive Magnetic Meteorites
A new tool to measure the magnetic signatures of big meteorites could not only aid NASA’s mission to Psyche; it could also help solve mysteries about how magnetic fields formed in our early solar system.
Tracking Trace Elements in the Ganga River
Levels of dissolved trace and heavy metals, which can be toxic, are highly variable across the river basin, concentrating in urban areas with high pollution but diluted by inflow from tributaries.
What Controls Giant Subduction Earthquakes?
Subduction zones with a low dipping angle and thick sediments can produce giant earthquakes; this finding lets researchers estimate worst-case scenarios for coastlines around the world.
Structural Style Controls Crustal Fluid Circulation in Andes
Variations in hot spring geochemistry from adjacent mountain ranges with different styles of faulting highlight the influence of crustal-scale structures on circulating fluids in the Peruvian Andes.
New Data from Earth’s Largest Non-Volcanic Rift Margin
Seismic reflection images combined with petrological data provide new constraints on the nature of the basement in the enigmatic Australia-Antarctic oceanic-continent transition zone.
