Ice-shelf buttressing and the stability of marine ice sheets
Ice-shelf buttressing and the stability of marinetype ice sheets are investigated numerically. Buttressing effects are analysed for a situation where a stable grounding line is located on a bed sloping upwards in the direction of flow. Such grounding-line positions are known to be unconditionally unstable in the absence of transverse flow variations. It is shown that ice-shelf buttressing can r...
متن کاملAdaptive mesh, finite volume modeling of marine ice sheets
Continental scale marine ice sheets such as the present day West Antarctic Ice Sheet are strongly affected by highly localized features, presenting a challenge to numerical models. Perhaps the best known phenomenon of this kind is the migration of the grounding line — the division between ice in contact with bedrock and floating ice shelves — which needs to be treated at sub-kilometer resolutio...
متن کاملIce sheets viewed from the ocean: the contribution of marine science to understanding modern and past ice sheets
Over the last two decades, marine science, aided by technological advances in sediment coring, geophysical imaging and remotely operated submersibles, has played a major role in the investigation of contemporary and former ice sheets. Notable advances have been achieved with respect to reconstructing the extent and flow dynamics of the large polar ice sheets and their mid-latitude counterparts ...

متن کاملPolymer translocation into laterally unbounded confined environments.
Using Langevin dynamics simulations in three dimensions, we investigate the dynamics of polymer translocation into the regions between two parallel plane walls with separation R under a driving force F. Compared with an unconfined environment, the translocation dynamics is greatly changed due to the crowding effect of the partially translocated monomers. The translocation time tau initially dec...
