Impact!: Asteroids and the Science of Saving the World

These entries follow researchers as they document the unfolding ecological dynamics of a pristine volcanic island (Surtsey) and trace the paths of asteroids that could potentially reach Earth (Impact). Surtsey features Erling Olafsson, an entomologist with a lifelong interest in the volcanic island that formed off the coast of Iceland in 1964. He was part of the first science team on the island when he was just a college student and, over a decades-long career, has continually returned to Surtsey to observe the growth and diversification of life there. Impact profiles a collection of astronomers, geologists, and meteorite hunters to examine the history of strikes to Earth and gauge the risks of future encounters. The discussion ends with a fascinating look at the technologies proposed (or in development) to protect Earth from a major impact. Both volumes prominently feature the research methods and tools of science. Burns, who traveled with Icelandic researchers to Surtsey, meticulously documents every detail of life in a remote field station, from the particulars of trapping insects to the extremes taken to minimize human impact on the island. Vivid photographs of field locations in both volumes convey, respectively, the rocky landscapes of Surtsey and its inhabitants and the impressive size of the Arizona impact crater. Impact also contains excellent diagrams, maps, and artistic renderings. Extensive appended resources point readers to additional information. danielle j. ford
