Short summary
The compaction of firn provides valuable insights into the physical processes involved in the transition from snow to ice. Investigations into how temperature influences firn deformation across samples taken from various depths reveal distinct microstructural characteristics, including variations in density and other parameters. Firn exhibits different mechanical behaviors compared to fully dense ice, primarily due to its lower density, elevated temperatures, and increased effective stresses.
