Full description

Here we provide projections of Antarctic ice-free areas at the end of the 21st century under two RCP (Representative Concentration Pathways) carbon forcing scenarios (RCP4.5, RCP8.5). Each RCP has a 'mean' projection and a 'lower' and 'upper' bound, generated using mean, lower and upper melt coeffcients during the melt modelling. Methods used to derive the ice-free projections are detailed in Lee et al. 2017.

Lineage

Progress Code: completed
Statement: The current ice-free layer, that was used to project the future ice-free layers, is the 'medium resolution' rock outcrop layer from the Antarctic Digital Database (ADD) version 7 (add.scar.org). The projected melt was applied to the Bedmap2 'ice thickness' layer from the British Antarctic Survey (bas.ac.uk/project/bedmap-2/), in order to derive the future ice-free layers.

Notes

Purpose
These spatial layers were the output of Lee et al. 2017, where the primary purpose of the study was to determine how terrestrial Antarctic biodiversity habitat (ice-free areas) would be impacted by climate change.
