Retrogressive Thaw Slumps Produce a Changing Disturbance Regime for Arctic Stream Invertebrates

Global Change Biology, Volume 32, Issue 3, March 2026.
Climate change is causing permafrost to thaw, resulting in the formation of large craters in the ground called thaw slumps, which deposit sediments and nutrients into rivers and continually impact stream ecosystems over time. We returned to slump impacted streams 10 years after an initial sample period and found that slumps permanently change streams ...

Heat Flux Modeling on Debris-Covered Glaciers

, 2011
A one-dimensional heat flux model has been developed in this study to analyze changes in heat propagation within debris cover on a glacier and the subsequent melt. The model can accept data collected in situ for calculations of real modeled melt, and also synthetic data based on simple wave forms and debris physical characteristics.

Barcoding‐Inferred Biodiversity of Shallow‐Water Indo‐Pacific Demosponges

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim The Indo‐Pacific is the world's largest marine biogeographic region. It is characterised by different degrees of connectivity among its subregions and harbours the majority of demosponge species currently known to science. Comparisons between regional sponge faunas have been undertaken in the past, mostly based on morphological species ...

Oceanic δ13C Fingerprints Caused by Laurentice Ice Sheet Discharges: Model‐Data Comparison During Heinrich Event 4

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract This study investigates the sensitivity of the oceanic circulation and δ13C ${\delta }^{13}C$ of the dissolved inorganic carbon to ice discharge events from the Laurentide ice sheet (LIS), using an isotope‐enabled and coupled climate–ice sheet model, and observations. The ice discharges are triggered by either reduced friction at the ice sheet‐

Pleistocene Smoothing and Resurfacing of Appalachian Ridgelines by Periglaciation

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Pleistocene cold periods created widespread periglacial conditions across mid‐latitudes, but isolating their geomorphic impact from modern climate, tectonics, and rock strength is challenging. We studied Appalachian (Eastern U.S.) ridgelines across a paleoclimate gradient, controlling for bedrock and structure, to test if colder periglacial ...
