This book provides an overview of the current state of knowledge of Arctic ice shelves, ice islands and related features. Ice shelves are permanent areas of ice which float on the ocean surface while attached to the coast, and typically occur in very cold environments where perennial sea ice builds up to great thickness, and/or where glaciers flow off the land and are preserved on the ocean surface. These landscape features are relatively poorly studied in the Arctic, yet they are potentially highly sensitive indicators of climate change because they respond to changes in atmospheric, oceanic and glaciological conditions. Recent fracturing and breakup events of ice shelves in the Canadian High Arctic have attracted significant scientific and public attention, and produced large ice islands which may pose a risk to Arctic shipping and offshore infrastructure. Much has been published about Antarctic ice shelves, but to date there has not been a dedicated book about Arctic ice shelves or ice islands. This book fills that gap.

What begins as a training run with sled dogs turns into a race against time for Tatum and her new friend, a Siberian Yupik boy named Cole. When a freak blizzard hits this remote island off the coast of Alaska, the duo seeks shelter overnight in a dilapidated hunting cabin. Their harrowing ordeal goes from bad to worse when wind-driven snow forces them to risk an alternate route. Stranded in the untamed wilderness, they must rely on each other—as well as their faithful huskies—to survive sub-zero temperatures and bone-numbing exhaustion. Worse still, their food supply is dangerously low. The most daunting decision comes when the strongest dog runs away. One person must go for help, while one must stay behind. Either way, they'll both be alone in the wild for an uncertain amount of time.
