Join Exploratorium Senior Scientist Paul Doherty as he shows us a demo related to Antarctic ice! Paul demonstrates how using Antarctic ice can help tell us what the temperatures of the earth's oceans were, thousands of years ago. They are many ways that people commute to work in the morning — some by car, or bus, or maybe walk or ride a bike. Getting to work in Antarctica can be just as varied. One of them is by helicopter. This footage was shot during a trip to Westhaven Nunatak, Antarctica. Dr. Marvin Speece, professor of geophysical engineering at Montana Tech and co-Principal Investigator of the Offshore New Harbor Project, discusses how their expedition collects scientific data. We speak to Robin Bell from the AGAP (Antarctic Gamburtsev Province) expedition. This is the first systematic study of our planet's last unexplored mountain range. This webcast was our first this season, and we had some technical difficulties. The POLENET project installed their newest high-precision GPS system on Deverall Island, Antarctica. These GPS systems tell scientists how much the ground underneath the ice sheet is moving upward. This has important implications on the movement of the West Antarctic Ice Sheet and its interplay with the rock below. Learn more about it in this audio report from correspondent Kelly Carroll. Thanksgiving Day weather at McMurdo Station, Antarctica, turned out to be pretty interesting, as weather always can change quickly here. Our holiday weekend greeted us with 50 mph winds, but it didn’t affect the great feast we had in the dining hall. In this audio dispatch, correspondent Jack Walter describes his first week at the team's field camp on the West Antarctic Ice Sheet. Hear about their research on lakes under the glaciers and get a slice of life as a remote polar scientist. In this audio dispatch, correspondent Saffia Hossainzadeh describes her journey to her team's deep field site via a stop at Siple Dome station. In part one, hear about the difficulties involved in escorting 700 pounds of explosives through Antarctica. In this audio dispatch, correspondent Saffia Hossainzadeh describes her journey to her team's deep field site via a stop at Siple Dome station. In part two, hear about our combat-style landing at Siple Dome’s remote air strip.
