G44A:
Glacial Isostatic Adjustment and the Importance of High-Quality Instrumental and Geological Constraints I


Submit an Abstract to this Session


Session ID#: 57907

Session Description:
Models of the Glacial Isostatic Adjustment (GIA) process continue to play a fundamental role in our understanding of Earth-Ice-Ocean interactions. The increasing availability of high-quality constraints on sea level evolution, crustal motion and the gravitational field of the planet has provided further insight on the evolution of the dynamic Earth system. In this session, we invite contributions that are focused upon: (1) the development and analysis of instrumental and geological records relevant to the study of the GIA process (which include, but are not limited to, geological reconstructions of relative sea level change, tide gauge records, satellite altimetry measurements, space-geodetic measurements of crustal motion and satellite gravimetric measurements); (2) the refinement of regional and global GIA models based upon this information (including new information on the viscosity structure of the Earth and on the evolution of continental ice cover); and (3) the insights on paleoclimate evolution that such analyses provide.
