A Tour of the Cryosphere. DVD produce by NASA in 2005. "In a little more than seven minutes, some of the best data visualizers at NASA's Goddard Space Flight Center lead viewers across the icy reaches of Antarctica, the drifting expanse of polar sea ice, the shrinking cap around the North Pole, and more. The tour travels around the world in a single "shot"; there are no abrupt cuts or scene changes. The effect of this technique helps convey the interconnectedness of the cryosphere to the rest of the world, and also helps viewers feel that they are not so distant from the world's snow and ice assets. The video also highlights the scientific importance of continued collection of this kind of data, and why NASA is uniquely qualified to study the Earth."
