Ice cores and offshore sedimentary records demonstrate enhanced ice loss along Antarctic coastal margins during millennial-scale warm intervals within the last glacial termination. However, the distal location and short temporal coverage of these records leads to uncertainty in both the spatial footprint of ice loss, and whether millennial-scale ice response occurs outside of glacial terminations. Here we present a >100kyr archive of periodic transitions in subglacial precipitate mineralogy that are synchronous with Late Pleistocene millennial-scale climate cycles.

This premise inspires us to combine atomic layer deposition (ALD) and magnetron sputtering (SPU) within a single chamber-supttering atomic layer augmented deposition (SALAD). SALAD takes full advantage of both ALD's precise and accurate precursor delivery and SPU's versatility in choosing chemical elements.
