Seasonal Ice Dynamics Control the Timing of Crevasse Drainage at a Fast‐Flowing Outlet Glacier

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract Crevasse field drainage transfers at least half of the seasonal runoff from the surface to the bed of the Greenland Ice Sheet, but the patterns of drainage are complex and spatio‐temporally heterogenous. To better understand controls on crevasse drainage processes, we use an automated deep learning method to map the seasonal filling and ...

Current Status, Past Trends, and Future Projections of Renewable Forest Resources and Ecosystem Services Across the United States

open access: yesEarth's Future, Volume 14, Issue 6, June 2026.
Abstract Forest ecosystems provide essential services such as timber, water regulation, biodiversity, and recreation, yet they are increasingly influenced by the interplay between climate and socioeconomic forces. This study synthesizes findings from the 2020 Resources Planning Act (RPA) Assessment to evaluate how these factors affect historical trends

We Are in the Anthropocene—Now What?

open access: yesEarth's Future, Volume 14, Issue 6, June 2026.
Abstract While the term “Anthropocene” is well established across scientific disciplines and social spheres, interpretations are diverse. Taking account of the 2024 rejection by a geological commission to accept the Anthropocene as a geological epoch and the related scientific debate, here we offer a future‐oriented perspective from the viewpoint of ...

The Fate of Western Headwaters: Climate Controls on Base‐Flow Decline

open access: yesEarth's Future, Volume 14, Issue 6, June 2026.
Abstract Headwater streams comprise nearly 88% of the western U.S. river network and supply most of the region's surface water, making them especially sensitive to warming, snowpack loss, and drought. As surface‐water inputs decline, groundwater increasingly sustains streamflow, elevating the need to understand long‐term trends in base flow and their ...

Determining the Character of Subglacial Sediments in the Ice‐Bedrock Interface Zone of Antarctica Using Horizontal‐to‐Vertical Spectral Ratios (HVSRs) of Seismic Ambient Noise

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Interactions between the Antarctic Ice Sheet and the underlying solid Earth occur within the ice‐bedrock interface zone (IBIZ), containing structures of sediments and rocks that strongly influence ice sheet dynamics. Existing insights into the Antarctic IBIZ come primarily from interpretations of airborne geophysical data and active seismic ...
