Revealing firn structure at Dome A region in East Antarctica using cultural seismic noise [PDF]
The CryosphereAntarctica is mostly covered by snow, firn, and glacier ice, and the transformation from snow to firn and glacier ice influences energy transfer and material transport in polar regions.

A synthetic study of acoustic full waveform inversion to improve seismic modelling of firn
Annals of Glaciology, 2022 The density structure of firn has implications for hydrological and climate modelling and for ice shelf stability. The firn structure can be evaluated from depth models of seismic velocity, widely obtained with Herglotz-Wiechert inversion (HWI), an ...

Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract Accurately estimating Snow Water Equivalent (SWE) in glacierized regions is critical for glacier modeling and mass balance analysis yet remains challenging due to sparse observations and uncertainties in precipitation products. The objectives are twofold: (a) assess how well three widely used precipitation datasets—Stage IV (a radar–gauge ...

The Thermal Conductivity of Polar Firn [PDF]
, 2021 A custom device is designed, validated, and used to make the first reported direct measurements of the effective thermal conductivity of polar firn. The firn cores spanned depths from 8 to 47 m from an undisturbed site near the South Pole in Antarctica ...

Climatic and insolation control on the high-resolution total air content in the NGRIP ice core [PDF]
Climate of the Past, 2016 Because the total air content (TAC) of polar ice is directly affected by the atmospheric pressure and temperature, its record in polar ice cores was initially considered as a proxy for past ice sheet elevation changes. However, the Antarctic ice core TAC

Hot water drilling in the firn layer of Greenland's percolation zone
Annals of Glaciology, 2021 The intermixed thermal and structural framework of cold firn, water-saturated firn and ice layers in Greenland's percolation zone can be challenging to penetrate with core drills.

Statistical Model of Subsurface Scattering Bias in ICESat‐2's ATL06 Product
Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract ICESat‐2 uses visible laser pulses and photon‐counting detectors to range the Earth's surface, providing precision altimetry for measuring ice sheet elevation change. However, since water ice is transparent to visible light, the photon returns recorded by ICESat‐2's ATLAS instrument may originate from subsurface scattering inside the snow or ...

MICROWAVE SIGNATURE OF POLAR FIRN AND SEA ICE IN THE ANTARCTIC FROM AIRBORNE OBSERVATION [PDF]
, 1992 P(論文)Airborne observations of 19.35 GHz microwave radiation were taken over the sea ice and firn cover of Antarctic ice sheet. Microwave brightness temperature was analyzed to explain satellite observations.As for the polar firn over the ice sheet ...

Concerning the Deposition and Diagenesis of Strata in Polar Firn [PDF]
Journal of Glaciology, 1988 Abstract Depth hoar in polar firn forms when large temperature gradients act on low-density firn, but high-density firn does not develop into depth hoar. Low densities in firn may be depositional (burial of surface hoar or still-air snowfall) or diagenetic (mass loss to the free atmosphere, typically in autumn); however, diagenesis is
