Simulations of ice-shelf rifting on Larsen C Ice Shelf Data DOI: https://doi.org/10.15784/601718 Cite as Huth, A. (2023) "Simulations of ice-shelf rifting on Larsen C Ice Shelf" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/10.15784/601718. AMD - DIF Record(s) USAP-2139002_1 Abstract This dataset contains a model (Elmer/Ice Fortran modules) to simulate rifting on ice shelves. The model combines the vertically integrated momentum balance and anisotropic continuum damage mechanics formulations. Additionally, it accounts for rift-flank boundary processes, including pressure on rift-flank walls from seawater, contact between flanks, and ice mélange that may also transmit stress between flanks. This dataset also contains the input data (Elmer restart files), input files (Elmer .sifs), and Slurm batch scripts to run five experiments. All experiments aim to simulate the final two years of rift propagation that led to the calving of tabular iceberg A68 from Larsen C ice shelf in 2017. However, each experiment differs in its treatment of rift-flank boundary processes, which affects the rift path. For more information, see the associated publication (Huth et al., 2023).
