The land ice contribution to sea level during the satellite era (2017, background): “Third, under certain circumstances the position of the grounding line can be inherently unstable and small changes in, for example, ocean temperatures, can result in a rapid retreat of the grounding line and, as a consequence, ice mass loss (Schoof 2007). slope (where the bed deepens inland).”
Marine ice sheet dynamics: Hysteresis and neutral equilibrium (2009, methodology): “[47] In agreement with the BL theory results [Schoof, 2007a], a marine ice sheet is unstable on an upsloping bed, confirming once again the marine ice sheet instability hypothesis proposed by Weertman [1974].”
Marine ice-sheet profiles and stability under Coulomb basal conditions (2015, methodology): “(5b) ensures continuity with the stresses in the ice shelf (Schoof, 2007b).”
Observation and Parameterization of Ablation at the Base of Ronne Ice Shelf, Antarctica (2010, background): “Mass exchange at the ice shelf base is the most important driver of changes in ice shelf thickness, and these, through the dynamic coupling between ice sheet and ice shelf (Schoof 2007), affect the discharge of grounded ice to the ocean and hence global eustatic sea level.”
Coupling of ice‐shelf melting and buttressing is a key process in ice‐sheets dynamics (2010, background): “In particular, enhanced coastal discharge is worrying for regions where the bedrock lies below sea level (i.e. marine ice‐sheets) because the retreat of ice‐streams may initiate large scale collapse [Schoof, 2007].”
Contribution of Antarctica to past and future sea-level rise (2016, neutral): “27, and an internal condition on ice velocity at the grounding line 15 that captures MISI (Fig.”
Tipping points: Early warning and wishful thinking (2010, background): “[7] In ocean general circulation models [Rahmstorf, 1995], in ice‐sheet dynamics [Schoof, 2007] and in an”
The stability of grounding lines on retrograde slopes (2012, background): “The question of WAIS being potentially subject to a marine ice-sheet instability (MISI) is of utmost importance for any quantitative estimates of future sea level change, because it raises the possibility of WAIS rapidly contributing several meters of sea level change.”
Grounding line movement and ice shelf buttressing in marine ice sheets (2009, methodology): “More subtly, ice flux at the grounding line in his model is actually an increasing function of both, ice thickness and longitudinal stress [see also Schoof, 2007b, section 4.2].”
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).”
