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. This video captures the energy and excitement of traversing across the sea ice to the Offshore New Harbor Field Camp. In this interview from Greenland, glaciologist Mark Fahnestock describes the roar of a 1000-foot iceberg dropping off the Jakobshavn Isbræ into the Ilulissat Icefjord. Includes time-lapse photography of this massive calving event. What controls the speed of Greenland’s big outlet glaciers like the Jakobshavn? How do they interact with the climate system? And most importantly, what does the future hold for the glaciers of Greenland? In this video, glaciologist Mark Fahnestock discusses glacier dynamics and what he hopes to learn through his studies. An interview with Mel Zucker, Professor of Geology, Skyline College, San Bruno, California.
In the early 1900s, German meteorologist Alfred Wegener suggested that the earth's continents were once a single landmass that had somehow split into pieces, drifting their separate ways. Geologists the world over called his idea preposterous. Decades later, their ridicule shifted to admiration as new tools developed by the military to map the ocean floors revealed the engine that drives the continents' movement. Geology professor Mel Zucker tells the story of this brilliant earth scientist and how, long after his death, science finally caught up with Wegener's crazy idea.
The Ice Stories crew caught up with glaciologist Mark Fahnestock on his way back home after a few weeks camping near Greenland's Jakobshavn Isbræ, the most productive and among the fastest-moving glaciers in the world. In this interview, Mark describes some of the physics of this speedy glacier and why so many scientists are interested in studying the dynamics of Jakobshavn.
