Emergence of Antarctic mineral resources in a warming world

This dataset includes ice-free land changed projected in Antartica for the low, moderate, and high ice melt scenarios described in Lucas et al. (2026). Triangular grids are provided, covering both positive (emerged) and negative (lost) land changes occurring at five selected times (2100, 2150, 2200, 2250, 2300) relative to the reference at 2015. These grids include the total (signed) change and the (signed) fraction of ice-free land change resulting from sea level change only.

## Description of the data and file structure

The three tar archives - Lmelt.tar, Mmelt.tar, and Hmelt.tar - include ice-free land computed in Antarctica for the low, moderate, and high ice melt scenarios described in Lucas et al. (2026). Triangular grids are provided, covering both positive (emerged) and negative (lost) land changes occurring at five selected times (2100, 2150, 2200, 2250, 2300) relative to the reference at 2015. These grids include the total (signed) change and the (signed) fraction of ice-free land change resulting from sea level change only.

There are 20 grids in each folder, saved in three files (thus, 60 items in each folder): {*xyz_xx, *ll_xx, *tri_xx}, where:

\* = {L, M, H} for low, moderate and high melt, respectively

xx = [01, ..., 20] file number to be detailed below

xyz - coordinate portion..., , **Changes after Jan 13, 2026:**&nbsp;Added sea level model output for the high, moderate, and low ice melt scenarios.&nbsp;
