Simulating Greenland Ice Slabs and Firn Aquifers with a 1D Firn Model
The Greenland Ice Sheet (GrIS) has been losing mass at an accelerating rate, primarily due to meltwater runoff to the ocean. Firn, a porous transition layer between snow and ice, has the potential to buffer the GrIS’s contribution to sea level rise by retaining this meltwater.Nikola Jovanovic +2 more

Different components and properties of the ice deposits on the earth (glaciers, ice sheets) store information on the climate and environment. We can mainly distinguish between three storage types: a) properties and isotopie composition of the ice itself, b) solid (and liquid) trace substances in the ice, and c) gaseous and volatile components.

Calibrating a compressible firn rheology and application to firn in shear zones
Most existing firn densification models are one-dimensional and empirical, limiting their ability to accurately represent complex stress regimes. For instance, they fail to account for enhanced densification in shear zones. In contrast, the Gagliardini and Meysonnier 1997 (GM97) model offers a more comprehensive approach by incorporating a compressibleAslak Grinsted +2 more

Nitric Acid in Firn: Discussion
1995Post-depositional changes in the HNO3 content of polar snow and firn limit our ability to infer past atmospheric concentrations and changes in concentration from an analysis of NO3 -in polar ice cores. Nitrate is present in snow, firn and polar ice both as HNO3 and as nitrate salts, and is a widely measured parameter in ice cores.
