  1. Reference data package supports evaluation of sea ice altimetry
    A standardized collection of sea ice measurements from 1993–2024 enables validation of satellite altimetry thickness products across both polar regions at matching spatial and temporal scales.
  2. Freshwater and carbon export to northern Alaska estuaries increased
    Model-based analysis reveals intensified freshwater and organic carbon discharge to northern Alaska's Beaufort Sea estuaries driven by permafrost thaw and hydrological cycle changes.
  3. Microbial methane release identified in inner Laptev Sea subsea permafrost
    Triple-isotopic analysis reveals old microbial methane from subsea permafrost drives methane release in the inner Laptev Sea, contrasting with thermogenic sources elsewhere on the Arctic shelf.
  4. Bias-corrected Greenland accumulation maps align more closely with observations
    A statistical method corrects biases in Greenland ice sheet snow accumulation estimates from climate models, reducing uncertainties in sea-level rise projections.
  5. Freeze–thaw cycling changes concrete–soil interface shear behavior
    Study investigates interfacial shear behavior between concrete and crushed rock-soil under freeze-thaw cycling, developing an improved constitutive model for permafrost infrastructure durability.
  6. Cross-shelf methane cycling was detected in the Laptev Sea
    Biomarker analysis reveals enhanced methane cycling across the Laptev Sea shelf overlying thawing subsea permafrost, using C30 hopanoid isotopic signatures as time-integrated proxies for aerobic.
  7. Sentinel-2 classifies Yellow River ice types with high accuracy
    Sentinel-2 remote sensing classifies Yellow River ice types with 94.91% accuracy using support vector machine algorithm, enabling operational monitoring for water resource and hazard management in.
  8. Arctic bioclimatic extremes have increased in many areas
    Seven-decade reanalysis reveals sharp increases and spatial shifts in Arctic bioclimatic extremes—droughts, winter warming and rain-on-snow—signaling novel stressors for cold ecosystems.
