Changes in glaciers and ice sheets are expected to have a tremendous influence on sea-level rise and global climate change.Many mathematical challenges in simulating ice sheet dynamics arise: ill-conditioned systems; a wide range of scales; complex evolving geometries; ill-posed inverse problems; sparse observational data; large-scale forward and inverse UQ problems in high-dimensions(“curse of dimensionality").Speakers in this MS will present recent developments aimed at overcoming these and other difficulties arising in ice sheet modeling.A broad range of topics will be covered,including forward and inverse problems,UQ,solvers/preconditioners,and coupling to global climate models.
