Tracer models and ice sheets

By combining models for ice dynamics with tracer models the distribution of tracers in ice sheets can be modeled, including layering of the ice sheet and isotopic profiles. Comparing the results to observations from boreholes, ice cores and internal radar reflectors provides a new method to validate model performance. The tracer method developed by Clarke and Marshall 2002 traces depositional age and position by a semi-Lagrangian scheme.
