... Land to the Scott Glacier area. The late Cenozoic volcanism is >30 Ma; the Wais >10 Ma, but the oldest ice presently comprising the WAIS and the Ross Ice Shelf is 100,000-200,000 Ka at most. Therefore it is not surprising that few samples of the volcanic debris erupted into the ice, but removed by g ...

Cryosphere
The cryosphere (from the Greek κρύος kryos, ""cold"", ""frost"" or ""ice"" and σφαῖρα sphaira, ""globe, ball"") is those portions of Earth's surface where water is in solid form, including sea ice, lake ice, river ice, snow cover, glaciers, ice caps, ice sheets, and frozen ground (which includes permafrost). Thus, there is a wide overlap with the hydrosphere. The cryosphere is an integral part of the global climate system with important linkages and feedbacks generated through its influence on surface energy and moisture fluxes, clouds, precipitation, hydrology, atmospheric and oceanic circulation. Through these feedback processes, the cryosphere plays a significant role in the global climate and in climate model response to global changes. The term deglaciation describes the retreat of cryospheric features.
