Inductive Approach Reveals Controls on Dissolved Organic Carbon
Machine learning leverages large data sets to reveal hidden patterns explaining when, where, and why dissolved organic carbon moves from hillslopes to streams.
The Western Great Basin Has an Arsenic Problem—Blame Its Geology
A new study links geological factors such as faulting and geothermal activity to an elevated risk of arsenic contamination in private wells across the Great Basin.
Topography Along the Apennines Reflects Subduction Dynamics
Topography and exhumation vary strongly along the Apennines, reflecting the geometry of the Moho and different geodynamic mechanisms.
Decoding the Secrets of Shifting Sediments
In the small-scale details of grain shape, researchers have found a new way to understand how sediment flows in a river, a process shaping Earth’s landscapes.
Roughed-Up Hillsides Reveal Tree-Toppling Winds
Researchers are reading pockmarks in the forest floor to study the uprooting of trees in southern Indiana and estimate how fast winds howled through the forest in the past.
Scientists EEAGER-ly Track Beavers Across Western United States
Efficiently tracking nature’s engineers—beavers—at the scale of entire watersheds over time is now possible, thanks to a new artificial intelligence–trained model called EEAGER.
Why Do Fluvial Valleys Behave So Differently?
Source: AGU Advances Editors’ Highlights are summaries of recent papers by AGU’s journal editors. The shape of fluvial valleys results from the complex interaction between climate and the local environment. Our current knowledge suggests that river discharge and valley-wall lithology are the main controls on valley width. Yet, current models based on these observations fail […]
Coseismic Displacement of 1987 Earthquake from Aerial Images
Differencing digital surface topography models constructed from historical aerial photographs reveal the coseismic surface displacement field of the 1987 earthquake in northern New Zealand.
Rain Makes Skulls Bigger—in Mice
New research shows how regional weather, shaped by towering mountain ranges, might influence the size and shape of local rodents.
