## Summary

This talk was presented on 2020 April 18 at the 2019-20 NASA Arizona Space 
Grant Symposium. The event was virtually available via Zoom.


Submitted abstract:

Since the last glacial maximum (LGM) ~20,000 years ago the Earth has 
deformed in response to the melting of large ice sheets. This 
deformation is known as glacial isostatic adjustment (GIA). The GIA is 
critical to understanding therate of uplift of the rockbed which 
contributes to sea-level changes, flexure response of surrounding 
rockbed, and understanding the rheology of the mantle. This project 
contributes to current knowledge of how GIA uplift will change going 
into the future. Greenland has had significant ice mass loss since 2003 
and ongoing GIA deformation since LGM. Slepian functions and GRACE 
gravity data were used to calculate the ice mass loss in Greenland to 
construct a forward model of the GIA for Greenland based on the next 100 
years of ice loss. This is important for finding when the GIA signal 
will have a comparable value to GIA from earlier deglaciation periods.
