摘要:Climate model projections are often aggregated into multi-model averages ofall models participating in an intercomparison project, such as the CoupledModel Intercomparison Project (CMIP). The "multi-model" approach provides asensitivity test to the models' structural choices and ...

摘要:Ice shelves control the dynamic mass loss of ice sheets through buttressing and their integrity depends on the spatial variability of their basal mass balance (BMB), i.e. the difference between refreezing and melting. Here, we present an improved technique – based on satelli...

摘要:Coupled ice sheet–ocean models capable of simulating moving grounding linesare just becoming available. Such models have a broad range of potentialapplications in studying the dynamics of marine ice sheets and tidewaterglaciers, from process studies to future projections of ...

摘要:The East Antarctic ice sheet is likely more stable than its West Antarcticcounterpart because its bed is largely lying above sea level. However, theice sheet in Dronning Maud Land, East Antarctica, contains marine sectorsthat are in contact with the ocean through overdeepened mar...

摘要:Subglacial lakes in Antarctica influence to a large extent the flow of the ice sheet. In this study we use an idealised lake geometry to study this impact. We employ a) an improved three-dimensional full-Stokes ice flow model with a nonlinear rheology, b) a three-dimensional flui...

摘要:Marine ice-sheet stability is mostly controlled by the dynamics of the grounding line, i.e. the junction between the grounded ice sheet and the floating ice shelf. Grounding line migration has been investigated within the framework of MISMIP (Marine Ice Sheet Model Intercompariso...

摘要:We present results of a multi-methodological approach to characterize theflow regime of West Ragnhild Glacier, the widest glacier in Dronning MaudLand, Antarctica. A new airborne radar survey points to substantially thickerice (>2000 m) than previously thought. With a discha...

摘要:Finding suitable potential sites for an undisturbed record of million-year old ice in Antarctica requires slow-moving ice (preferably an ice divide) and basal conditions that are not disturbed by large topographic variations. Furthermore, ice should be thick and cold basal condit...

摘要:We present the results of the first ice sheet model intercomparison project for higher-order and full-Stokes ice sheet models. These models are compared and verified in a series of six experiments of which one has an analytical solution obtained from a perturbation analysis. The ...

摘要:Predictions of marine ice-sheet behaviour require models that are able to robustly simulate grounding line migration. We present results of an intercomparison exercise for marine ice-sheet models. Verification is effected by comparison with approximate analytical solutions for fl...
