(2017). Flow-line model results for 2 trajectories on Larsen C Ice Shelf (Version None) [Data set]. Polar Data Centre; British Antarctic Survey, Natural Environment Research Council; Cambridge, CB3 0ET, UK.. https://doi.org/10.5285/d363ff21-1576-4ad6-a2e8-bbc3c0a39b06 The datasets are output from a flow-line model designed to estimate the age and surface origin for various ice bodies identified within hot-water drilled boreholes on Larsen C Ice Shelf (Hubbard et al., 2016, Ashmore et al., 2017). Two trajectories, based on remotely sensed velocities, allow surface fluxes from a regional climate model to be accumulated and advected down flow from selected points on the shelf. Vertical strain rates are taken into account, and surface mass balance is converted to thickness according to density profiles based on borehole data (Ashmore et al., 2017). The model output has a 250m horizontal resolution. These data are part of a larger project. The flow-line model code, the SMB datasets, and the borehole density profiles are also available.
