AGU editors recognize the contributions of peer reviewers in 2025, whose expertise and dedication were integral to the advancement of the Earth and space sciences.

A multi-decadal field dataset combined with reduced-complexity modeling approach highlights the importance of shoreline change in controlling alongshore variability of dune evolution.

Channel steepness is a popular metric in most studies of tectonic geomorphology, but the simple and convenient method of defining channels in the first place may have overlooked a serious pitfall.

A decade of NASA airborne radar surveys produces the most extensive inventory of glacier ice thickness for Alaska and northwestern Canada to date.

A shift in perspective: flume experiments show that grain entrainment is far more complex than traditional models suggest.

A physics-informed digital twin uses high-resolution temperature data to track, update, and predict permafrost conditions beneath an Alaskan embankment road.

Multi-temporal UAV oblique photogrammetry reveals significant fine-scale variability in Antarctic snow roughness driven by surface type, measurement scale, model choice, and meteorological conditions.

Laboratory experiments reveal that gravity wave-turbidity current interactions (combined flows) can enhance sediment transport to the deep ocean.

Glen’s Law describes the simple physics of ice flow that underpins ice sheet models, but parameter choices substantially influence the outcome of model projections.

Geophysical observations of the subglacial topography of Coats Land reveal a landscape formed by tectonics and fluvial erosion that influenced the formation of the East Antarctic Ice Sheet.

The fate of barrier islands in presence of sea level rise depends on their underwater shape.

Erosion in mountain-basin systems driven by long-period climate variations is buffered by an erosion saturation effect, which weakens peak erosion and leads to reduced sediment flux.

We use particle tracks from laboratory experiments to study grain velocities and activity subject to fluid flows from different directions Our sand bed strengthens under unidirectional flows, but...

Surface depressions on Helheim Glacier appear at a consistent location on the lee side of a subglacial ridge and have increased in frequency Observed calving episodes, regardless of calving style...

AGU editors recognize the contributions of peer reviewers in 2024, whose expertise and dedication are integral to the advancement of the Earth and space sciences.

Using small-scale physical experiments, the mobility of rock-ice avalanches is linked to variability in the earth materials that are encountered along the flow runout path.

This EO is an unconstitutional attempt to censor and punish U.S. scientists for publishing science that doesn't fit a political agenda This misleading and false misrepresentation of U.S. scientif...

The channel threads in braided river systems may be more predictable than previously thought.

Two different novel force-balance models are used to estimate grain mobility thresholds using resistance force and microtopography data An automated point cloud segmentation approach is compared ...
