Self-consistent Ice Dynamics, Accumulation, Delta-age, and Interpolation of Sparse Age Data using an Inverse Approach
Entry ID: waddington_0636997

[ Update this Record ]

Summary
Abstract: We provide a the synthetic, sparse depth-age data generated using a 1-d ice-flow model. The age data include red noise to simulate real depth-age data.
The inferred depth-age data profile are included.

This data set provides the necessary information for model inter-comparison purposes.

Purpose: The intellectual merit of this project is that to develop new interpolation methods that calculate layer thinning over time due to ice-flow mechanics. Accurate interpolation also requires a spatial and temporal accumulation history. These three issues are coupled through accumulation patterns and ice-core dates. This project will develop an integrated inversion procedure to solve all three problems simultaneously. The new method will incorporate ice-penetrating radar profile data and ice-core data, and will find self-consistent: spatial/temporal accumulation patterns; delta-age profiles for ice cores; and reliably interpolated depth-age profiles.
