In the late 1500s, Dutch navigator William Barrents sailed north in search of a Northeast Passage to Asia. This expedition and a second one both suffered hardships, but they were mild in comparison with the horrors of the third expedition. Andrea Pitzer talks about the Arctic voyages of William Barents and their impact on Europe for centuries to come. Pitzer is a journalist and author of Icebound: Shipwrecked at the Edge of the World.
