  • The ongoing expansion of seismic networks into cryospheric regions, which will be capable of detecting local thermal‐contraction‐induced cracks, in combination with the fact that such cracks can erode and weaken the ice, and thereby serve as meltwater and heat channels, warrants further research to better understand these near‐surface processes and to monitor ice properties.

  • While process‐based SWE projections remain elusive, the collection of ground‐penetrating radar (GPR)‐derived data sets provides a greatly enhanced perspective on the spatial distribution of SWE and will pave the way for future work that may eventually allow such projections.

    End‐of‐winter snow depth variability on glaciers in Alaska · 2015 · DOI

  • Seasonal snow strongly influences groundwater recharge in mountain aquifers, yet its role in mid-altitude karst systems under climate warming remains poorly quantified.

    Impact of seasonal snow on the recharge of a mountain karst aquifer under climate change: the Dévoluy case study (Southern Alps, France) · 2026 · DOI

  • Importantly, velocity residuals allow for us to see that runoff- driven acceleration occurs for all glaciers but its impact is limited to the early melt season.

  • It remains to be demonstrated that clathrates persist long enough to move with the ice from the deepest part of the glacier trough to the calving front where overburden stress is considerably lower.

    Freshly calved icebergs from Sermeq Kujalleq in Kangia, Greenland: is their blue ice temperate? · 2026 · DOI

  • Critically, fully automated and systematic monitoring of lake area changes is lacking, yet such monitoring is essential for detecting anomalous changes, estimating water storage, and understanding lake-glacier feedbacks.

    Glacial Lake Observatory (GLO): annual dataset of glacial lakes in Nepal and transboundary catchments (2017–2024) · 2026 · DOI

  • However, direct observations of snow mass are sparse in space and time, forcing most reconstructions to rely on snow models driven by uncertain meteorological inputs.
