Peering Through Titan’s Haze to Better Understand Its Surface
Variations in grain size and water ice content detected on Saturn’s largest moon offer evidence of geologically related units that resemble the mountain-to-desert transition on Earth.

Depth Matters in Peat Bog Nutrient Cycling
Peatlands store around a third of Earth’s soil carbon, and a new study begins to reveal how the ecosystems’ organic matter changes with depth.

A Novel Way to Map Debris Thickness on Himalayan Glaciers
By combining changes in elevation with other data, scientists have developed a method for estimating the thickness of debris covering glaciers on whose water more than 800 million people depend.

Challenging the Day Diagram, a Rock Magnetism Paradigm
A critique of the plot routinely used to determine bulk magnetic properties concludes the technique is so ambiguous that new approaches to understanding magnetic mineral assemblages must be developed.

What Shaped the Northern Apennine Deformation Front?
An integrated interpretation of well and seismic reflection data from Italy’s Po Valley shows the range’s undulations are controlled by the slope and composition of two major gliding horizons.

A Consistent Model of Ice Dissociation on Celestial Bodies
A model based on decades of experimental results can now quantify the products of water ice dissociation caused by radiation and predict the products expelled into an icy body’s outer atmosphere.
