Experimental protocol for sea level projections from ISMIP6 stand-alone ice sheet models [PDF]
The Cryosphere, 2020 Projection of the contribution of ice sheets to sea level change as part of the Coupled Model Intercomparison Project Phase 6 (CMIP6) takes the form of simulations from coupled ice sheet–climate models and stand-alone ice sheet models, overseen by the ...

The influence of inter-annual temperature variability on the Greenland Ice Sheet volume
Annals of Glaciology, 2023 The Greenland Ice Sheet has become an increasingly larger contributor to sea level rise in the past two decades and is projected to continue to lose mass.

PISM-LakeCC: Implementing an adaptive proglacial lake boundary in an ice sheet model [PDF]
The Cryosphere, 2022 During the Late Pleistocene and Holocene retreat of paleo-ice sheets in North America and Europe, vast proglacial lakes existed along the land terminating margins.

An ice sheet model validation framework for the Greenland ice sheet [PDF]
Geoscientific Model Development, 2016 Abstract. We propose a new ice sheet model validation framework – the Cryospheric Model Comparison Tool (CmCt) – that takes advantage of ice sheet altimetry and gravimetry observations collected over the past several decades and is applied here to modeling of the Greenland ice sheet.

A parallel implementation of the confined–unconfined aquifer system model for subglacial hydrology: design, verification, and performance analysis (CUAS-MPI v0.1.0) [PDF]
Geoscientific Model Development, 2023 The subglacial hydrological system affects (i) the motion of ice sheets through sliding, (ii) the location of lakes at the ice margin, and (iii) the ocean circulation by freshwater discharge directly at the grounding line or (iv) via rivers flowing over ...

Reply to “Basal buoyancy and fast-moving glaciers: in defense of analytic force balance” by C. J. van der Veen (2016) [PDF]
The Cryosphere, 2017 Two approaches to ice-sheet modeling are available. Analytical modeling is the traditional approach (Van der Veen, 2016). It solves the force (momentum), mass, and energy balances to obtain three-dimensional solutions over time, beginning with the ...

Nonlinear response of the Antarctic Ice Sheet to late Quaternary sea level and climate forcing [PDF]
The Cryosphere, 2019 Antarctic ice volume has varied substantially during the late Quaternary, with reconstructions suggesting a glacial ice sheet extending to the continental shelf break and interglacial sea level highstands of several meters.

Dynamically coupling full Stokes and shallow shelf approximation for marine ice sheet flow using Elmer/Ice (v8.3) [PDF]
Geoscientific Model Development, 2018 Ice flow forced by gravity is governed by the full Stokes (FS) equations, which are computationally expensive to solve due to the nonlinearity introduced by the rheology. Therefore, approximations to the FS equations are commonly used, especially when

Ambiguous stability of glaciers at bed peaks
Journal of Glaciology, 2022 Increasing ice flux from glaciers retreating over deepening (retrograde) bed topography has been implicated in the recent acceleration of mass loss from the Greenland and Antarctic ice sheets.
