Even distance does not provide adequate perspective on all things.
In terms of the cryospherethe frozen stretches of the planet that
act as the Earth's thermostat--the best way to fully appreciate its
importance is not only from orbiting observatories, but also through
the data they collect.
That data forms the backbone of this extraordinary visual tour. 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.
NASA has packaged up two versions of the Tour of the Cryosphere for
The first presents narration with the video; the second presents the
video without narration, but uses a dramatic musical score and on-
screen annotations as you traverse the planet. You will find
versions of each video, plus related still images in multiple screen
sizes and resolutions at our main download site.
