Construction of late Pleistocene ice history model that is consistent with Composite Rheology and 3D material property variations

u3004164 - Posted on 06 January 2016

Project Description: 

Based on the mantle rock experiment results, we want to modify the relationship between stress and strain in mantle to be nonlinear. Besides, as seismic tomography indicates the earth material properties vary strongly in lateral direction, this will also be refined.
Constrcuting thickness history models of the huge ice sheets with the correction mentioned above, explain all the geologic and geodetic observations of GIA.
We will use the ABAQUS finite element software package to help us do calculation, making the spatial resolution at the surface of 1x1 degree grid,even 0.5x0.5 if it is possible, which is a much higher resolution compare with the majority of temporary models.

Research Project Details
Project Duration: 
09/2015 to 09/2017
Project Significance: 
The results of the study has important and wide applications: the model of ice sheet history constructed can be used for climate simulation, leading to a better understanding of climate change in the past, present and future; figure out the global sea level change source and help the monitoring of global warming. Deeper understanding of GIA induced sea level change in significant to coastal engineering and impact the large human population that lives near the coast. Provide important correction for dynamic geodetic height reference system, which is required in positioning and in engineering construction projects.
Results Achieved: 
Not yet so far.
Remarks: 
We will use the ABAQUS finite element software package which we use through HPC to help us do calculation, making the spatial resolution at the surface of 1x1 degree grid, even 0.5x0.5 if it is possible, which is a much higher resolution compare with the majority of temporary models.
