A helicopter pilot flies biologists to the edge of the sea ice, where they collect algae samples under the curious gaze of emperor penguins. Two seal researchers find their way back to camp through a blizzard. A school-teacher helps scientists collect air samples at the crater edge of an active volcano, and a biologist hears the first, high-pitched chirps of hatching Adelie penguins. In this riveting book, Rebecca Johnson shows these women and more, who live and work in the cold, wild continent of Antarctica.
