Inversion of basal friction in Antarctica using exact and incomplete adjoints of a higher‐order model (2013, methodology): “Goldberg and Sergienko [2011] showed that for a hybrid model [Schoof and Hindmarsh, 2010; Goldberg, 2011], the exact adjoint may be advantageous in some cases to minimize the cost function.”
The Potsdam Parallel Ice Sheet Model (PISM-PIK) – Part 1: Model description (2010, methodology): “, Huybrechts, 1990; Ritz et al., 2001) solve the SIA and the SSA in distinct map-plane regions, which results in an abrupt change in flow type across the grounding line. Pollard and Deconto(2009) combine both shallow approximations via a heuristic shear stress correction and an additional grounding ”
