      A Tour Of The Cryosphere Reveals The Frozen Assets Of Earth


      Greenbelt MD (SPX) Dec 07, 2005
      Even distance does not provide adequate perspective on all things.
      In terms of the cryosphere—the 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
      download.

      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.
