| Summary: | Climate change and the associated rise in temperatures have raised concerns about Antarctica's substantial contribution to sea level rise and climate change. Evaluating this impact involves utilizing ice flow models, where the implementation of ice rheology plays a crucial role in influencing predictions. Ice is an anisotropic material, meaning as ice flows, crystals within it align in response to compression and extension, forming what is known as "ice fabric." Ice fabric properties significantly affect ice flow dynamics. However, many models currently assume isotropic ice behavior, mainly due to limited observational data and the complexity involved in incorporating ice fabric anisotropy into the models. This assumption poses challenges in accurately predicting Antarctica's impact on sea level rise and climate change. To address this issue and improve the precision of ice flow models, it is essential to develop methodologies to enhance the quantity of observational data pertaining to ice fabric properties, ... |
