Direct measurements of firn-density evolution from 2016 to 2022 at Wolverine Glacier, Alaska

Journal of Glaciology
Knowledge of snow and firn-density change is needed to use elevation-change measurements to estimate glacier mass change. Additionally, firn-density evolution on glaciers is closely connected to meltwater percolation, refreezing and runoff, which are key

Current situation of glacier and snow glades in the southern mountain area of Lesser Caucasus province

Вісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія
Problem definition. The rise in air temperature due to the impact of global warming causes the melting of glaciers in mountainous regions and accelerates freshwater scarcity in lowland areas.

Antarctic-wide ice-shelf firn emulation reveals robust future firn air depletion signal for the Antarctic Peninsula

Communications Earth & Environment
Antarctic firn is critical for ice-shelf stability because it stores meltwater that would otherwise pond on the surface. Ponded meltwater increases the risk of hydrofracture and subsequent potential ice-shelf collapse.

High‐Resolution Characterization of the Firn Layer Near the West Antarctic Ice Sheet Divide Camp With Active and Passive Seismic Data

Geophysical Research Letters
We construct a high‐resolution shear‐wave velocity (VS) model for the uppermost 100 m using ambient noise tomography near the West Antarctic Ice Sheet Divide camp.

Microwave brightness of polar firn as measured by Nimbus 5 and 6 ESMR [PDF]

The microwave emission from a half-space medium characterized by coordinate dependent scattering and absorbing centers was calculated by numerically solving the radiative transfer equation by the method of invariant imbedding.
