Datasets and models for "No general stability conditions for marine ice-sheet grounding lines in the presence of feedbacks"

This repository contains datasets shown in figures  (figs.tar.gz) of the manuscript "No general stability conditions for marine ice-sheet grounding lines in the presence of feedbacks" (doi: 10.1038/s41467-022-29892-3) and COMSOLTM models (model.tar.gz) used in the study. A folder “figures” contains data displayed on the corresponding figures. The data sets in folders “Fig1a’” and “Fig1b” are from  Kittel et al. (2021) for Antarctica and Fettweis et al. (2017) for Greenland. All other data are outputs of numerical simulations with COMSOL models contained in a folder “model”. The models have been created with COMSOL Multiphysics version 5.6.0.401 and Optimization Module.
