Project Title

Paleo-sea Level Change

Brief Description for General Publications

The main purpose of the project is to investigate paleo sea-level change and predict current change in sea level and ice volume. We use observations of sea-level change to refine our numerical models for ice sheets and determine the rheological parameters that give the best fit between the observed values of RSL and model predictions. At each step in the inversion process RSL calculations will be performed for a single ice model in combination with a large series of earth models spanning the plausible range of rheological parameter values. The resulting model predictions will then be compared with the observational database to determine the combination of ice- and earth-models that yields the best fit. The best-fit model predictions will then be examined in detail to determine if any regional or temporal patterns exist that may suggest further possible refinements to the ice sheet before the next step of the inversion process is undertaken.
