Impacts of Transient Critical Zone Evolution on Landslide Susceptibility and Hazard Across the Utuado Batholith, Puerto Rico

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract Landscapes in humid climates often experience rapid chemical and mechanical weathering that can change groundwater fluxes, drainage pathways, and frictional strength via alterations in subsurface mineral composition and matrix porosity. These changes to hillslope critical zone structure and strength should control landslide susceptibility ...

Characterizing the subglacial environment of lower Thwaites Glacier using radar modeling

Journal of Glaciology
Understanding the spatial heterogeneity beneath Thwaites Glacier, West Antarctica, is vital to projecting its impact on future sea levels. Radar-echo sounding (RES) is commonly used to infer subglacial conditions, but these data can be challenging to ...

Historical surface mass balance from a frequency-modulated continuous-wave (FMCW) radar survey from Zhongshan station to Dome A

Journal of Glaciology, 2020
Using frequency-modulated continuous wave radar data from the 32nd Chinese Antarctic Research Expedition in 2015/16, subsurface profiles were obtained along an East Antarctic inland traverse from Zhongshan station to Dome A, and four distinct regions ...

Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...

Associations Between the Seasonal Darkening of the Greenland Ice Sheet and the Duration of Bare Ice

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract Darkening of the Greenland ice sheet is known to amplify surface melting. Here, analysis of automatic weather station (AWS) data around the ice sheet and satellite‐derived albedo data reveals that the bare ice duration (BID) is a predictor of the average albedo during summer (June through August, JJA, α¯JJA ${\bar{\alpha }}_{\mathrm{JJA ...

Geography and ‘The New’

Transactions of the Institute of British Geographers, Volume 51, Issue 3, September 2026.
ABSTRACT This Intervention reflects on the multiple, contradictory and ambivalent relations human geography has with ‘the new’. Some sort of relation with the new is an inescapable and necessary part of all practices of knowledge generation. Newness, whether it be an empirical finding, an idea, a concept or an approach, can fuel the interest, wonder ...

Flume experiments on macro‐roughness elements: Hydraulic response and potential influences on flood risk and habitat diversity

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Physical modelling of macro‐roughness elements for river restoration showed that backwater rise depends mostly on the relative structure width and approaching flow Froude number, with only minor differences among designs. Internal geometry modulated turbulent kinetic energy and flow partition between gap and wake.
