JG01 - INTERACTIONS OF SOLID EARTH, ICE SHEETS AND OCEANS (IAG, IACS, IASPEI)
Measurements of solid Earth, sea-level and ice-sheet change are influenced by a complex interaction of processes occurring over a large range of spatial and temporal scales. Proxy observations that constrain past ice sheets are influenced
by glacial isostatic adjustment and changing mantle dynamic topography. Present-day observations of solid Earth deformation in one location are affected by present and past changes in global surface loading. Recent work highlights the role that solid Earth
deformation has to play in controlling ice-sheet change, while seismological investigations are revealing crucial spatial variations in Earth rheology. In this symposium, we showcase model- and data-driven efforts to understand feedbacks between surface load
changes and the solid Earth over all timescales.
Topics of interest include (but are not limited to):
observations of mass changes in the cryosphere and oceans, and their interaction with solid Earth deformation
influence of mantle dynamic topography and glacial isostatic adjustment on paleo observations of sea level or ice sheet behaviour
seismic studies of the rheology of the solid Earth in the context of sea-level and ice-sheet studies
