Data and Imagery
NSIDC's World Glacier Inventory contains information for thousands of glaciers, including parameters such as location, area, length, orientation, elevation, and classification of morphological type and moraines. You can also visit the Advanced Data Search page to search NSIDC's online data catalog (use the search term "glaciers").
The Glacier Photo Collection includes thousands of photos, primarily of Alaskan glaciers, but also of glaciers in the Pacific Northwest (U. S. and Canada) and Europe.
Global Land Ice Measurements from Space (GLIMS) is an international project tasked with surveying a majority of the world's 160,000 glaciers. See GLIMS Data at NSIDC.

Satellite Image Atlas of Glaciers of the World is provided by the USGS Global Change Research Program.
The Norwegian Water Resources and Energy Directorate's (NVE) Web site provides mass balance measurements for glaciers in Norway, glacier length change observations, a remotely sensed glacier inventory, a subglacial observatory, and a database of glacier hazards.
Glacier Lake Outburst Flood Early Warning System at Rundvassbreen, Blåmannsisen provides information on glacier lake outburst floods (GLOFs). It includes real-time data for GLOF monitoring and early warning at Blåmannsisen (Northern Norway), as collected jointly by NVE, University of Oslo, and Elkem Energi Salten (Siso/Lakshola). The site also contains background material on GLOFs in Norway.
Global Glacier Changes: Facts and Figures: This 2008 report, compiled by the United Nations Environment Programme, includes data on global and regional glacier changes.
