Antarctica is a vast and dynamic place, but radar technologies -- from World War II-era film to state-of-the-art miniaturized sensors -- are enabling scientists to observe and understand changes beneath the continent's ice in unprecedented detail. Join radio glaciologist Dustin Schroeder on a flight high above the ice to learn about future sea level rise (and the habitation of icy moons) and see how ice-penetrating radar is helping us understand what the melting means for us all.
