Firn Model Intercomparison Experiment (FirnMICE)
Journal of Glaciology, 2017 Evolution of cold dry snow and firn plays important roles in glaciology; however, the physical formulation of a densification law is still an active research topic.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.Abstract The West Antarctic Ice Sheet (WAIS) contains an ice volumetric equivalent of 5.3 m of global mean sea‐level rise. Understanding the climate mechanisms that influence WAIS surface mass balance (SMB) can help reduce uncertainties in sea‐level rise projections. Previous work has focused on trends related to temperature and the roles of well‐known

Seasonal Ice Dynamics Control the Timing of Crevasse Drainage at a Fast‐Flowing Outlet Glacier
AGU Advances, Volume 7, Issue 3, June 2026.Abstract Crevasse field drainage transfers at least half of the seasonal runoff from the surface to the bed of the Greenland Ice Sheet, but the patterns of drainage are complex and spatio‐temporally heterogenous. To better understand controls on crevasse drainage processes, we use an automated deep learning method to map the seasonal filling and ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.Abstract Interactions between the Antarctic Ice Sheet and the underlying solid Earth occur within the ice‐bedrock interface zone (IBIZ), containing structures of sediments and rocks that strongly influence ice sheet dynamics. Existing insights into the Antarctic IBIZ come primarily from interpretations of airborne geophysical data and active seismic ...

Firn air composition at the H128 and NDFN sites, Dronning Maud Land, East Antarctica [PDF]
Air sampled from polar firn is useful for reconstructing atmospheric composition over the last few decades and understanding the trapping processes of air in the ice sheets, as well as determining the age of air relative to the ice at the same depth ...

Radio-echo soundings of sub-polar glaciers with low-frequency radar
, 1991 Air-borne radio-echo soundings of sub-polar glaciers in Svalbard have previously been carried out by Soviet scientists using high frequency radar units of 620 and 440 MHz. Later a British/Norwegian group made soundings with 60 MHz equipment.

On the Rates of Growth of Grains and Crystals in South Polar Firn [PDF]
Journal of Glaciology, 1969 The size of firn crystals as a function of age has been investigated in thin sections to a depth of 49 m at the South Pole. Grain cross-sections increased in size from 0.24 mm2 at 0.1 m depth to 0.63 mm2 at 10 m. Crystals, as distinct from grains, increased in size from 0.18 to 0.43 mm2 over the same interval, implying that grains are generally ...

Trichinella sp. in polar bears from Svalbard, in relation to hide length and age
, 2010 Diaphragm and masseter muscles from 376 polar bears ((irsur maririmus), 252 ringed seals (Phocn hispida), 84 bearded seals (Erignarhus barbarus), and 77 arctic foxes (Alopex lagopus) from Svalbard were examined for Trichinelln.
