International Symposium on Glaciers and Ice Sheets Contribution to Sea-Level Change (Observations, Modelling and Predictions)
Meeting participants are encouraged to present on a wide variety of topics. All these topics can be addressed using observations, forward or inverse modelling, theoretical analysis or the coupling of data and modelling through the use of data assimilation methods. The first six topics are more related to a specific interface and focus on local processes, whereas the last ones seek to address the large-scale response of ice mass. These include, but are not limited to:
Basal processes: effect of basal water, link between runoff and surface velocity, hydrological model, friction law linking basal hydrology and water pressure, drumlins and associated sub-glacial landforms.
Basal melting below ice-shelves and at the front of marine terminated glaciers, distribution and amount of melt, accretion of marine ice, coupling of ice sheet and ocean models.
Grounding line dynamics: marine ice sheet instability, observed rate of migration, positioning by various techniques, sensitivity of the rate of migration of grounding line to forcing regimes.
Calving processes: calving rate parameterization, damage modelling, numerical implementation in ice-sheet models.
Surface mass balance: snow accumulation and runoff, influence of refreezing in firn, coupling of regional climate and ice sheet models.
Ice body and rheology: anisotropy, temperature field within ice masses, borehole records, rheology of marine ice, modelling of englacial structure.
New generation of ice-sheet models, their numerical design, impact of mechanics, their coupling with ocean and/or climate.
Estimation of the contribution of glaciers and ice-sheets to sea level change: initialization (spin-up), forecast estimates of future sea level rise, ensemble methods, and associated error bars, paleo-reconstruction of past changes.
