“Something was wrong . . . My regulator had frozen open. My air supply was pouring out into the ocean.” Marine biologist Kathy Conlan’s account of a frightening moment while diving in Antarctica is an example of the candid and fascinating narrative put forward in Under the Ice . An accessible text and many photographs describe Conlan’s work studying the effects of pollution in Antarctica. Vivid details of the extreme conditions under which she worked convey both the harshness and grandeur of the region. (Ages 8-11)
