Glaciers - National Snow and Ice Data Center

Glaciers begin to form when snow remains in the same area year round, where enough snow accumulates to transform into ice. Each year, new layers of snow bury and compress the previous layers. This compression forces the snow to recrystallize, initially forming grains similar to the size and shape of sugar grains.

Two categories of glaciers exist: ice sheets and alpine glaciers. Ice sheets cover vast areas of land in broad domes. Alpine glaciers, are smaller, and found not only at the poles, but in high mountain regions across the globe.

There are over 200,000 glaciers distinct from the ice sheets; and if all of these glaciers were to melt, they would increase sea level by just under half a meter (1.6 feet). If the Greenland Ice Sheet were to melt, it would increase sea level by approximately 7.4 meters (24.3 feet) ; and if the Antarctic Ice Sheet were to melt, it would ...

Once the glaciers receded, seawater covered the floor of the glacial trough to create fjords. The famous Matterhorn in Switzerland displays three types of glacial erosion: Cirques are created when glaciers erode the mountainside, scouring into it and creating rounded hollows with steep uphill faces, shaped like tilted bowls. A cirque is often ...

The Largest Glaciers and Glacier Complexes in the World, Version 1 data set provides a list of the three largest glaciers and glacier complexes in each of the 19 glacial regions of the world as defined by the Global Terrestrial Network for Glaciers. The data are provided in shapefile format with an outline for each of the largest ice bodies ...

Movement of Glaciers. Glaciers move in one of two ways: internal flow or basal sliding. Internal flow happens due to the weight and shape of the ice. As the weight of the glacier puts pressure on ...

The NSIDC DAAC GLIMS data collection includes data from the Global Land Ice Measurements from Space (GLIMS) initiative. GLIMS is an international project to inventory the world?s glaciers and to create a comprehensive, global database of land ice through repeat surveys.This data collection?s primary data product is the GLIMS Glacier Database. The glacier database includes measurements of ...

They were programmed to snap continuous shots of glaciers during every hour of daylight for months or years on end. These were the photos that would eventually end up at NSIDC. In addition to the time-lapse photography, the project also captured beauty shots, which focused on the character of ice, and repeat photographic sequences taken from ...

Windnagel will also continue to investigate the differences between ice caps and glaciers and perform a glacial retreat analysis to determine which of the world?s glaciers are melting the fastest. In the future, she would like to use her findings to create new glacier data sets and educational and outreach materials.

Glaciers are huge masses of ice, snow, rock, sediment, and often liquid water that originate on land and move down slope under the influence of their own weight and gravity. The two main types are continental glaciers (or ice sheets) and alpine glaciers.
