Glaciers/Ice Sheets | NASA Earthdata
NASA's glaciers and ice sheet data help reveal ways these frozen giants influence our weather, climate, communities, and oceans. There are approximately 700,000 square kilometers of glaciers and ice sheets in the world located on every continent except Australia.
Ice Sheets | NASA Earthdata
2021年4月12日 · A continuous sheet of land ice that covers a very large area and moves outward in many directions. This type of ice mass is so thick as to mask the land surface contours, in contrast to the smaller and thinner highland ice. The continental glacier of Greenland is sometimes called the Inland Ice. Thi

The Global Ice-Sheet Mapping Observatory (GISMO) spaceborne radar system was a part of the NASA Instrument Incubator Project (IIP). The IIP program was designed to provide a testing opportunity for emerging technology in order to create …
where topography is steep and ice sheet surfaces are complex. ICESat-2 ATL03 photon cloud -based depth calculation on the Amery ice shelf. Photon heights (blue), depth calculation (green), refraction- corrected values shown in red. Melt pond shown from imagery collected within 3 days from LandSat (a), Planet Scope (b) and Planet SkySat (c).
the Greenland Ice Sheet sends more meltwater into the surrounding ocean. It also increases the rate of ice flow off Greenland, because the meltwater penetrates the ice sheet and forms a thin film between the ice and bedrock, which causes the glaciers to slide off the continent faster. A trend in lower concentrations of Arctic sea ice may
