Dependence of century-scale projections of the Greenland ice sheet on its thermal regime (2013, background): “…of the momentum balance equations, such as the shallow-ice approximation (SIA; Hutter, 1982), the shelfy-stream approximation (SSA; MacAyeal, 1989; Greve and others, 2011; Aschwanden and others, 2012a) or a combination of SIA and SSA (Bueler and Brown, 2009; Pollard and DeConto, 2009).”
Loss of cultural world heritage and currently inhabited places to sea-level rise (2014, background): “Keywords: sea-level rise, cultural heritage, chlimate impacts S Online supplementary data available from stacks.iop.org/ERL/9/034001/mmedia”
Convection-Driven Melting near the Grounding Lines of Ice Shelves and Tidewater Glaciers (2011, background): “Hughes (1973) suggested increased melting at grounding lines as a possible mechanism by which the marine-based West Antarctic Ice Sheet could be destabilized, and several other authors have echoed this view: most recently, Schoof (2007) and Pollard and DeConto (2009).”
Interacting tipping elements increase risk of climate domino effects under global warming (2020, background): “It is likely that the West Antarctic Ice Sheet has experienced brief but dramatic retreats during the past 5 Myr (Pollard and DeConto, 2009).”
The Potsdam Parallel Ice Sheet Model (PISM-PIK) – Part 2: Dynamic equilibrium simulation of the Antarctic ice sheet (2010, methodology): “There are several models combining the stress balance from the SIA for grounded ice with the SSA for ice shelves in simulations of the Antarctic Sheet-Shelf system (e.g., Huybrechts, 1990; Hulbe and MacAyeal, 1999; Ritz et al., 2001; Pollard and Deconto, 2009).”
Deconstructing the Last Glacial termination: the role of millennial and orbital-scale forcings (2011, background): “Finally, recent modeling studies (Philippon et al., 2006; Pollard and DeConto, 2009) suggest that the accelerated melting of the Antarctic icesheet started around 15 ka, further supporting the notion of significant deglacial freshwater forcing of the Southern Ocean during the ACR.”
A simple inverse method for the distribution of basal sliding coefficients under ice sheets, applied to Antarctica (2012, methodology): “Most previous paleoclimatic continental ice-sheet models have widespread (∼ 100s of m) errors in modern Antarctic surface elevations, with regional errors of 500 m or more (e.g., Ritz et al., 2001; Philippon et al., 2006; Pollard and DeConto, 2009; Martin et al., 2011; Whitehouse et al., 2012).”
Grounding-line migration in plan-view marine ice-sheet models: results of the ice2sea MISMIP3d intercomparison (2013, neutral): “Pollard and DeConto 2009, 2012) incorporated the boundary layer solution of Schoof (2007a) directly in a numerical ice-sheet model at coarse grid resolution, so the flux, q g , across model grounding lines is given by vertically averaged velocity, u ¼ q = h , where h is the ice thickness at the…”
Continental scale, high order, high spatial resolution, ice sheet modeling using the Ice Sheet System Model (ISSM) (2012, methodology): “This means that ISSM can be used to help and constrain long transient runs [Huybrechts et al., 1996; Ritz et al., 1997; Pollard and DeConto, 2009; Greve, 2005] so as to converge to accurate present time configurations.”
