Quick Facts What is a glacier? A glacier is an accumulation of ice and snow that slowly flows over land. Alpine glaciers are frozen rivers of ice, slowly flowing under their own weight down mountainsides and into vall...
What is a glacier? A glacier is an accumulation of ice and snow that slowly flows over land. At higher elevations, more snow typically falls than melts, adding to its mass. Eventually, the surplus of built-up ice begi...
Science What is the lifecycle of a glacier, and what factors influence its lifecycle? The amount of precipitation, whether in the form of snowfall, freezing rain, avalanches, or wind-drifted snow, is important to glac...
Glacier melt delivers nutrients into lakes, rivers, and oceans. Those nutrients can drive blooms of phytoplankton—the base of aquatic and marine food chains. Meanwhile, gradual glacier melt sustains stream habitats fo...
This data set comprises results from a hybrid glacier evolution model that uses the mass balance module of the Python Glacier Evolution Model (PyGEM) and the glacier dynamics module of the Open Global Glacier Model (O...
The Randolph Glacier Inventory (RGI) is a global set of glacier outlines; it is intended as a snapshot of the world’s glaciers. This data set provides a single outline for each glacier and is produced in coordination ...
This data collection’s primary data product is the GLIMS Glacier Database. The glacier database includes measurements of glacier geometry, glacier area, snowlines, supraglacial lakes and rock debris, and other glacial...
The World Glacier Inventory (WGI) contains information for over 130,000 glaciers. Inventory parameters include geographic location, area, length, orientation, elevation, and classification. The WGI is based primarily ...
Sea ice data is updated daily, with a one-day lag. On occasion, there is data delay which is usually resolved within a few days. The orange line in extent and concentration images (left and middle) and the gray line i...
