How Climate Change Shaped the Amazon’s Land and Life
Ice Age climate swings shaped the equatorial basin’s terrain—and possibly its ecology—faster than previously thought.
What a Gold Mining Mishap Taught Us About Rivers
Miners in Alaska rerouted a river to search for gold. One hundred years later, the new channel is teaching scientists how rivers shape Earth.
Grain Scale Dynamics During Barchan-Barchan Interactions
A new study pinpoints grain scale dynamics during binary interactions between barchan dunes.
Megaripples on Mars—How to Name Wind-Shaped Features on the Red Planet
New research suggests a more settled terminology for Martian aeolian landforms based on size and geomorphology.
Anderson Receives 2020 G. K. Gilbert Award in Surface Processes
Suzanne P. Anderson received the 2020 G. K. Gilbert Award in Surface Processes at AGU’s virtual Fall Meeting 2020. The award recognizes “sustained and outstanding contributions to the field of Earth and planetary surface processes from a mid-career or senior scientist.”
Powerful Glacial Floods Heave Himalayan Boulders
Many of the house-sized boulders that litter Himalayan river channels were transported thousands of years ago by glacial lake outburst floods, new observations suggest.
Tracing the Past Through Layers of Sediment
Signals in layers of sedimentary rock hint at climates and ecosystems come and gone. Understanding this history can help us forecast the future, but challenges abound.
Finding Natural Solutions to Man-Made Problems in River Deltas
Decades of research on river deltas identify gaps in our knowledge of delta behavior and the tools required to fill them in.
Reflections on the Legacy of Grove Karl Gilbert, 1843–1918
In the company of other explorers as passionate as he was about geomorphology, Gilbert derived one fundamental geological insight after another from the landscapes of the American West.
