Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
Understanding how glacier sliding and iceberg calving contribute to loss in ice sheet models can improve predictions of global sea-level changes. This is hampered by the inaccessibility of a glacier's base and its calving front.
