Reconciling observations and models of elastic and viscoelastic deformation due to ice mass change

Event Type: Conferences and Workshops

When: 30 May 2013 to 2 June 2013

Where: Ilulissat, Greenland

Past and present changes in the mass balance of the Earth's glaciers and ice caps induce present-day deformation of the solid Earth on a range of spatial scales, from the very local to global. Of principal interest are geodetic observations that validate, or may be assimilated into, models of glacial isostatic adjustment (GIA) and/or constrain models of present-day ice mass change through measurements of elastic rebound. Using geometric measurements alone, elastic and viscoelastic deformations cannot be separated without additional models or observations. The conference will focus on resolving these issues and work on dissemination of these measurements within the glaciological community.

Topics include:
*Observations of present-day changes in glaciers and ice sheets
*Measurements and models of elastic rebound
*Cryospheric deformation in low viscosity regions
*Reconciling models and observations of GIA
*Glacial isostatic adjustment on a heterogeneous Earth: Going beyond 1D Maxwell Earth models
