An interactive slide show explores the journey of a single snowflake onto and through a glacier. This journey, which can take as much as 30,000 years to complete, shows that the life cycle of a glacier can be more complex than originally perceived. Full description.

This video shows how a NASA glaciologist has learned about glaciers and how their formation could be related to climate change. It features nine fly-bys over 3-dimensional glaciers, live video footage of ice fronts calving into the sea, and picture sequences of historical and satellite data.. Length:13:15. Full description.

Wilson Alwyn Bentley (1865-1931), famous for his photomicrographs of snow crystals, prepared sets of glass lantern slides of dew, frost and ice crystals. Many of these sets found their way to colleges and universities around the United States. The University of Wisconsin's Department of Atmospheric and Oceanic Sciences donated their collection to the Schwerdtfeger Library in 2000. Shortly after, the ... Full description.

Users can read about the discovery of ice on Earth's moon, which occurs in the form of ice crystals accumulated near the lunar poles. The discussion covers the use of the neutron spectrometer as a tool for detecting water by sensing the hydrogen it contains, some ideas on the origin of the ice, and the fact that water has been found elsewhere in the solar system (on Europa, Jupiter's fourth-largest ...

In the Clouds Photography specializes in photos of weather skyscapes taken by a photographer who is also an atmospheric scientist. Spectacular images of tornadoes, lightning, supercells, and other related severe weather are available, as are weather photos of a less severe nature;strange cloud forms and optical phenomenon such as rainbows, halos, and glories. Weather-related photos are a specialty ... Full description.

The purpose of this lesson is for students to explore the nature and composition of a comet. The student will select ingredients to create a comet and will learn to identify ingredients responsible for a comet nucleus, and how changes in the nucleus when the comet approaches the Sun cause two different kinds of tails to form. Students can explore some facts, myths, and legends linked to the appearance ... Full description.

This site contains information about snow, glaciers, permafrost, sea ice and cryospheric trends. The cryosphere is the portion of the Earth's surface where water is in a solid form, usually snow or ice. Seasonal snow cover, the largest component of the cryosphere, covers up to 33 percent of the Earth's total land surface. Glaciers and ice sheets cover about 10 percent of the Earth's land area. Nearly ... Full description.

This is a single, stand alone image from the New York Times of a Glacier/iceberg flow. Location and other information is not provided. Full description.

This information about the Lunar Prospector mission to the Moon discusses the possibility that ice exists on the lunar surface. The article indicates that no native water ice has been found on the moon. If ice has been found, it most likely originated from meteors and meteorites which periodically bombard the lunar surface. Full description.

In this lesson, students learn about meteors, meteorites, and comets by reading and discussing a related New York Times article about the Leonid meteor showers and the methods that scientists are using to learn from these meteors. Students then create and observe a comet in their classroom. Full description.
