Modeling the geoid and polar motion in geological time
The main objective of our research is to: 1) conduct a correlation analysis of the relationship between geoid heights and topographic heights in the modern era using calculated moving correlation coefficients (MCC); 2) extrapolate the obtained correlation model to past geological epochs and determine the paleogeoid using known surface heights derived from paleoDEM continental reconstruction models (Scotese and Wright, 2018); 3) perform calculations of changes in "True Polar Wander" (TPW) based on the obtained paleogeoid height data sets resulting from the movement of lithospheric plates.
