Ice is sliding toward edges of Greenland Ice Sheet（图）
Ice toward edges Greenland Ice Sheet
2019/10/23
Ice on the Greenland Ice Sheet doesn’t just melt. The ice slides rapidly across its bed toward the ice sheet’s edges. As a result, ice is moving to high-melt marginal zones more rapidly than previousl...
Mass-conserving subglacial hydrology in the Parallel Ice Sheet Model version 0.6
Parallel Ice Sheet Model subglacial hydrology
2015/8/6
We describe and test a two-horizontal-dimension
subglacial hydrology model which combines till with a distributed system of water-filled, linked cavities which open
through sliding and close t...
Adding a dynamical cryosphere to iLOVECLIM (version 1.0): coupling with the GRISLI ice-sheet model
Adding a dynamical cryosphere iLOVECLIM GRISLI ice-sheet model
2014/12/19
We present a coupling approach to and the first results of the GRISLI ice-sheet model within the iLOVECLIM-coupled climate model. The climate component is a relatively low-resolution earth system mode...
A fully coupled 3-D ice-sheet–sea-level model: algorithm and applications
3-D ice-sheet–sea-level model algorithm
2014/12/19
Relative sea-level variations during the late Pleistocene can only be reconstructed with the knowledge of icesheet history.
Formulation, calibration and validation of the DAIS model (version 1), a simple Antarctic ice sheet model sensitive to variations of sea level and ocean subsurface temperature
Formulation calibration validation DAIS model simple Antarctic ice sheet model sensitive sea level ocean subsurface temperature
2014/12/19
The DCESS (Danish Center for Earth System Science) Antarctic Ice Sheet (DAIS) model is presented. Model hindcasts of Antarctic ice sheet (AIS) sea level equivalent are forced by reconstructed Antarcti...

sheet/climate model simulations is developed and demonstrated over the Greenland ice sheet u...
Description of a hybrid ice sheet-shelf model, and application to Antarctica
3 d ice model hybrid combination shallow ice floating ice shelf grounding line migration parameterized ice flow
2014/12/10
The formulation of a 3-D ice sheet-shelf model is described. The model is designed for long-term continental-scale applications, and has been used mostly in paleoclimatic studies. It uses a hybrid com...

Sheet Modelling Intercomparison Project experimental design
2014/12/10
During the mid-Pliocene warm period (3.264 to
3.025 million years ago), global mean temperature was similar to that predicted for the next century and atmospheric carbon dioxide concentrations were s...
A new coupled ice sheet/climate model: description and sensitivity to model physics under Eemian, Last Glacial Maximum, late Holocene and modern climate conditions
A new coupled ice sheet climate model description and sensitivity to model physics Eemian Last Glacial Maximum late Holocene modern climate conditions
2014/12/9
The need to better understand long-term climate/ice sheet feedback loops is motivating efforts to couple ice sheet models into Earth System models which are capable of long-timescale simulations. In t...
Interaction between ice sheet dynamics and subglacial lake circulation:a coupled modelling approach
ice sheet dynamics subglacial lake circulation coupled modelling approach
2010/2/3
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 f...
Weichselian interstadial sediments on Jæren (SW Norway)–paleoenvironments and implications for ice sheet configuration
Weichselian interstadial sediments paleoenvironments implications ice sheet configuration
2009/12/3
Interstadial glaciomarine sediments at Jæren in south-western Norway have been investigated for their composition, distribution and age, and a model for the depositional environment is proposed....
Testing hypotheses of the cause of peripheral thinning of the Greenland Ice Sheet:is land-terminating ice thinning at anomalously high rates?
hypotheses peripheral thinning Greenland Ice Sheet high rates
2010/2/4
Recent observations have shown that the periphery of the Greenland ice sheet (GrIS) is thinning rapidly and that this thinning is greatest around marine-terminating outlet glaciers. Several theories h...
