Book excerpt: One the least understood places in the world, the North and South poles have captivated the imagine of scientists, adventurers, and ordinary people for centuries. With an abundance of natural resources, including crude oil, and the possibility for new scientific breakthroughs, the race to understand the poles has at various times led many nations to make political claims in a rush to exercise control over this terrain. This comprehensive volume offers detailed accounts of the major polar explorations, the political and scientific stakes in the quest to map and contain the Arctic and Antarctica. Chapters discuss the contest for the North Pole, the "heroic age" of exploration of the South Pole during the beginning of the twentieth century, the evolution of scientific technology and its effect on research in the harsh environment, and the trends in modern polar research.
