Solid Water Liquid Rock
http://www.mindbites.com/lesson/10517 for full video. Ice and fire meet dramatically on the world's most southern volcano -- Antarctica's Mount Erebus. This film is an adventurous journey from the base of the volcano 300m under the sea to inside the erupting crater 3500m above sea level. See this extreme landscape, revealed as never before. As the film journeys from the volcano's base to its summit, we will compare the formation of ice crystals from water and snow with the formation of crystalline rock for lava. We start 1,500 feet underwater, where the previously unseen sea floor will be revealed by TVNZ's Remote Operated Vehicle. There should be a covering of fine volcanic sediment carried off Erebus by glaciers, and there will be strange creatures, including giant sponges, giant sea-spiders, and fish which use anti-freeze to survive in the sub-zero water. We trek to the summit at 12,500 feet. Because the atmosphere is thinner near the South Pole it is like breathing the air on a 15,000 feet mountain -- difficult. Anytime the temperature rises to minus 30 degrees Celsius it is a warm day. "
