Click to visit. http://www.exploratorium.edu/poles Meet glaciologist Slawek Tulaczyk and his team, who work in the fast-emerging field of ice sheet dynamics. No longer thought of as giant slabs of slow-moving frozen water, ice sheets are energized by a complex system of subglacial lakes, floods, streams, and ice quakes. This group will have just returned from a month at a remote camp on the West Antarctic Ice Sheet, and will have lots to tell us about their icy adventures. Fri, 16 May 2008 07:30:00 +0100 http://www.exploratorium.edu/poles Today, we’ll hook up with scientists at Palmer Research Station in the Western Antarctic Peninsula. This is one of the most rapidly warming places on earth, and the site of a Long Term Ecological Research (LTER) Project. The scientists are getting ready for a month-long research cruise off the shores of western Antarctica, to study how this rich marine ecosystem is responding to melting sea ice and global climate change. Fri, 16 May 2008 07:30:00 +0100 http://www.exploratorium.edu/poles Meet scientists and engineers at the South Pole who are hard at work drilling holes in the ice for a unique telescope called Ice Cube. When completed, this telescope will take up a .6 miles (1 cubic kilometer) of the ice sheet and consist of dozens of strings, each containing 60 detectors suspended in crystal-clear ice more than 4,900 feet (1500 meters) below the surface. Fri, 16 May 2008 07:30:00 +0100 http://www.exploratorium.edu/poles Join Exploratorium senior scientist Paul Doherty as he serves up more hands-on activities related to science in Antarctica. Fri, 16 May 2008 07:30:00 +0100 http://www.exploratorium.edu/poles David Ainley has been studying four colonies of Adelie penguins in Antarctica’s Ross Sea for over 20 years. Join us for a conversation with David and find out all about the population dynamics of penguins and how they’ve responded to environmental and climate change over time. Fri, 16 May 2008 07:30:00 +0100 http://www.exploratorium.edu/poles/ Today we wrap up our conversations with the ANDRILL Project scientists. As a special treat, we’ll speak with project leader and geologist Dave Harwood, who will offer an overview of the project and what lies ahead for it.

Fri, 16 May 2008 07:30:00 +0100 http://www.exploratorium.edu/poles Last winter, we covered the assembly of the South Pole Telescope. Today, we’ll revisit that process, discover what scientists have learned from the telescope so far, and find out, from project leader John Carlstrom, what work needs to be done this year as the scientists fine-tune this amazing new piece of technology. Fri, 16 May 2008 07:30:00 +0100 http://www.exploratorium.edu/poles/ Learn more about the ANDRILL scientists. Watch them examine a sediment core, find out about new developments, and discover ancient diatoms (single-celled marine organisms that leave behind beautiful skeletons) with geologist Christina Riesselman. Fri, 16 May 2008 07:30:00 +0100 http://www.exploratorium.edu/poles The ANDRILL Project is a feat of engineering. How do scientists drill and retrieve sediment cores from under the ice and sea, and why do they do it? We’ll talk with scientists and engineers at a sea-ice drill site and learn more about the ANDRILL Project. Fri, 16 May 2008 07:30:00 +0100
