Learn about atmospheric research at the South Pole from NOAA's Nick Morgan, the IceCube neutrino detector from Mark Krasberg and Laura Gladstone, and the South Pole Telescope from Bill Holzapfel.

Seems like a circular definition, but if you looked closely at sundials in the northern hemisphere, you'd notice that the shadow of the sun moves around the sundial in a "clockwise" direction. This was adopted by clock-makers and became the standard we know today. In the southern hemisphere, the sun's shadow moves around the dial in the opposite direction, so if clocks had been invented there, our watches would move the other way. Wed, 27 Jan 2010 08:30:00 +0100 http://www.exploratorium.edu/webcasts/index.php We speak with biologist David Ainley, who has been studying Adelie penguins in Antarctica for more than 25 years Wed, 27 Jan 2010 08:30:00 +0100 http://www.exploratorium.edu/webcasts/index.php Our Exploratorium team talks to scientists from POLENET (Polar Earth Observing Network). Wed, 27 Jan 2010 08:30:00 +0100 http://www.exploratorium.edu/webcasts/index.php UC Berkeley astrophysicist Bill Holzapfel takes us on a tour of the South Pole Telescope and explains how it is unlocking the secrets of the Universe. Wed, 27 Jan 2010 08:30:00 +0100 http://www.exploratorium.edu/webcasts/index.php We tour the NOAA Atmospheric Research Observatory at the South Pole where scientists are monitoring carbon dioxide levels, CFCs, solar radiation, and the ozone hole. Wed, 27 Jan 2010 08:30:00 +0100 http://www.exploratorium.edu/webcasts/index.php Our intrepid Exploratorium team shares experiences from their visit to Shackleton's hut. This hut is at Cape Royds, where Shackleton mounted an expedition to the South Pole and made a first ascent of Mt. Erebus. Wed, 27 Jan 2010 08:30:00 +0100 http://www.exploratorium.edu/webcasts/index.php We take a tour of Black Island, and speak with Tony Marchetti who for the last 13 years has been running this vital communications station for the U.S. Antarctic operations.
