Adélie penguins feeding chicks at Cape Royds, Antarctica. Adélie penguins walking across ice on the Ross Sea, Antarctica. Adélie penguins sitting on eggs in their nests at Cape Royds, Antarctica. Adélie penguins engaging in a behavior called tobogganning. Like sledding, penguins cruise along the slick ice on their bellies -- a faster way of traveling than by walking. 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.
