This 5-minute animation portrays fluctuations in the cryosphere through observations collected from a variety of satellite-based sensors. The cryosphere consists of those parts of the Earth's surface where water is found in solid form, including areas of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. In these regions, surface temperatures remain below freezing for a portion of each ... Full description.

Comment on this resource
The sea ice around Antarctica grows dramatically from late February, when large parts of the coast are ice-free, to October, when the amount of sea ice effectively doubles the size of the continent. The SeaWinds Scatterometer instrument on the QuikSCAT satellite captures this dramatic ebb and flow and shows the sea ice as dynamic and always moving, even in areas that are ice-bound. This animation ... Full description.

In this exercise, students investigate the mechanism for the isostatic support of mountains. Introductory materials explain the Archimedes principle (the weight of a floating solid is supported by the weight of the fluid that it displaces) and the concept of depth of compensation (the depth within a fluid where the pressures generated by overlying material are everywhere equal), and graphically display ...

This lithograph shows the break-off of a large iceberg from the Pine Island Glacier in West Antarctica. This event occurred between November 4th and 12th, 2001, and provides powerful evidence of rapid changes underway in this area of Antarctica. The images were acquired by the MISR instrument onboard NASA's Terra spacecraft. Full description.

Comment on this resource
The Pine Island Glacier is the largest discharger of ice in Antarctica and the continents fastest moving glacier. Even so, when a large crack formed across the glacier in mid 2000, it was surprising how fast the crack expanded, 15 meters per day, and how soon the resulting iceberg broke off, mid-November, 2001. This iceberg, called B-21, is 42 kilometers by 17 kilometers and contains seven years of ... Full description.

This news article examines evidence that parts of the Antarctic ice sheet have undergone episodes of instability that appear to correspond with periods of unusually warm temperatures in the Northern Hemisphere during the last ice age. Full description.

C-19 iceberg that calved off the Ross Ice shelf and its companion B-15 iceberg, which is anchored near the coast. The two large bergs may have disrupted normal ocean circulation that clears the Ross Sea of seasonal ice during the first months of austral summer. The ice remained in the sea long past previous thaw dates, and created trouble for ships trying to bring in supplies to McMurdo research station ... Full description.

This slide show follows a snowflake through its life in a glacier. The path of the ice crystal is traced from its incorporation in the zone of accumulation, through the zone of ablation to its final departure, whether being calved as an iceberg or melting or sublimated. There is also information on the speed of the glacier and the difference between a cold and a warm glacier. Full description.
