Flow-line model results for 2 trajectories on Larsen C Ice Shelf
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.
Funding was provided by the NERC grant NE/L005409/1.

Methodology:
The data are model output. The model is also available. Further details are in Bevan et al. (2017). V90, V100 and V110 refer to 90%, 100% and 110% input velocity magnitude. 75pc, med and 25pc refer to lower quartile, median and upper quartile of the surface mass flux estimate.

Data quality:
Six output datasets are included. For each of two flowlines - the best estimate plus versions based on +10% (-10%) velocity magnitude combined with the lower (upper) quartile of mean SMB from 1979 to 2014.
