Ice Sheets Today - National Snow and Ice Data Center
Jan 8, 2025 · Ice Sheets Today offers the latest satellite data and scientific analyses on surface melting of the Greenland Ice Sheet in the Northern Hemisphere and Antarctic Ice Sheet in the Southern Hemisphere. Surface melt on each ice sheet results from a combination of daily weather conditions and the amount of solar energy absorbed by its snow and ice.
About the Greenland Ice Sheet - National Snow and Ice Data Center
Nov 21, 2012 · Greenland Ice Sheet Today offers the latest satellite data on surface melting of the Greenland Ice Sheet. Surface melt on the ice sheet results from daily weather conditions that are driven by air temperatures, winds, and feedback effect from changes in …
Ice Sheets - National Snow and Ice Data Center
Ice caps are essentially miniature ice sheets. An ice cap covers less than 50,000 square kilometers (19,300 square miles) and comprises several merged glaciers. Like ice sheets, ice caps tend to spread out in dome-like shapes as opposed to occupying a single valley or set of connected valleys.
Ice Sheet Quick Facts - National Snow and Ice Data Center
The Greenland Ice Sheet contains about 2.9 million cubic kilometers (0.7 million cubic miles) of ice. The ice sheet extends about 1.7 million square kilometers (656,000 square miles), covering 80 percent of the world’s largest island, and is equivalent to about three times the size of Texas.
Glacier Quick Facts | National Snow and Ice Data Center
Presently, 10 percent of land area on Earth is covered with glacial ice, including glaciers, ice caps, and the ice sheets of Greenland and Antarctica. Glacierized areas cover over 15 million square kilometers (5.8 million square miles).
Melt Data | National Snow and Ice Data Center
In addition to generating daily maps and graphs of surface melt data, Ice Sheets Today provides the following data tools with a focus on the Greenland Ice Sheet. Greenland Surface Melt Extent Interactive Chart. Explore the interactive graph below and look at …
Greenland Ice sheet Mapping Project (GrIMP)
The Greenland Ice sheet Mapping Project (GrIMP) creates and provides benchmark data sets for observing Greenland ice sheet change and stability. The temporal range of data ranges from the year 1985 to present.
Glaciers - National Snow and Ice Data Center
What are ice caps and icefields? An ice cap is a dome-shaped glacier with an area less than 50,000 square kilometers (19,300 square miles) that flows in all directions and covers much of the underlying topography. Ice caps form in high-latitude polar and subpolar mountain regions.
No medal for Greenland melt in 2024 - National Snow and Ice …
Aug 14, 2024 · While snowfall in June and July covered dark bare ice areas on the ice sheet's margins, a heat wave in early July exposed this ice in western Greenland, increasing melt in that region. Temperatures so far this summer have been near the 1991 to 2021 average.
How does Arctic sea ice affect the Greenland Ice Sheet?
Oct 30, 2020 · Sea ice melt near Greenland can affect ice on the island in a couple ways. As sea ice retreats from the fronts of marine-terminating glaciers, the glaciers lose stability and may flow faster.
