Abstract:
The flow-line model was designed to enable estimation of the age and surface origin for various ice bodies identified within hot-water drilled boreholes on Larsen C Ice Shelf. Surface fluxes are accumulated, converted to thicknesses, and advected down flow from a fixed number of selected points. The model requires input datasets of surface mass balance, surface velocity, vertical strain rates, ice-shelf thickness, and a vertical density profile.
This model is part of a larger project. Input datasets such as density profiles and trajectory vectors are available separately.
Resolution is dependent on the input datasets.
Funding was provided by the NERC grant NE/L005409/1.
