In May 2009, the ROV Jason captured these images of violent explosions of the West Mata volcano near Fiji. At almost 4,000 feet underwater, this is the deepest erupting volcano ever witnessed and captured on video. It's also the first time anyone has ever observed the formation of deep-ocean seafloor as it's happening. At the South Pole, the Ice Stories crew met up with correspondent Zoe Courville just before she and her team embarked on their 3,000 km traverse across the desolate and frigid East Antarctic Ice Sheet. In this video, Zoe gives us a tour of the vehicles they are taking on their cross-continent journey, including their living module, sleeping quarters, and science sled. You might be surprised to know that water is one of the most scarce resources in Antarctica. Why do the hands on clocks go "clockwise?" 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. We speak with biologist David Ainley, who has been studying Adelie penguins in Antarctica for more than 25 years A Kenn Borek Basler (Turbo DC-3) taxis, takes-off, and flies low back over the field at Williams Airfield outside McMurdo Station, Antarctica Our Exploratorium team talks to scientists from POLENET (Polar Earth Observing Network). Kenn Borek Basler(s) (more accurately called a Turbo DC-3) at the Williams Field which services McMurdo Station, Antarctica. 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. 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.
