This short video summarizes all of the steps in collecting an ice core using the Deep Ice Sheet Coring (DISC) drill. Thomas Bauska, of Oregon State University helped Heidi Roop put together this video. Have you ever wondered exactly what clouds are made of, or what the difference is between a cumulus and lenticular cloud? Clouds are an ever-present, ever-changing part of our natural landscape. They come in a huge variety of shapes and sizes, and capture our imagination with their endless permutations. Join Exploratorium Senior Scientist Paul Doherty for a live Webcast about cloud physics. Paul will discuss the basic makeup of clouds, and explore some of the aspects that make them such a rich part of our daily lives.
As a special event in conjunction with the 2009 American Geophysical Union Fall Meeting, we connected a live audience at the Exploratorium with scientists at the South Pole. 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. Most things won't burn on Mars—after all, the main ingredient in the Martian atmosphere, carbon dioxide, is used in fire extinguishers on earth. So how would one create fire without oxygen? Use metal!This slow motion footage shows magnesium burning within a block of dry ice.
Geologist Chistina Riesselman explains how studying 3-million-year-old sediment from Antarctica is providing a glimpse of what our planet's climate might look like if atmospheric carbon dioxide continues to rise as projected. Sarah Santos and Jeremy Rector demonstrate two ways to make ferrofluid during a live Webcast of the Exploratorium's Iron Science Teacher.

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. In this panel discussion, the panelists will examine the impacts of climate change on Hawaiian ecosystems and populations. The panelists will include:
Phil McGillivary, Leon Geschwind, Amber Inwood, and Ku’ulei Rogers. As part of the ECHO Climate Change Symposium, join artist Xavier Cortada as he discusses some ways that the world is participating in actions around climate change.
