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. Smashcast visited the Exploratorium on Saturday, April 18th, to work on the Ice Stories project and meet four Antarctic scientists. 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. In this interview from in front of the Canada Glacier in Antarctica’s Taylor Valley, Hassan Basagic from Portland State University describes the essential role of polar glaciers in supporting the bare-bones ecosystems in the Dry Valleys.
