(4) 4-6 Turnstone Ocean Explorer Book series. The quest to explore the depths of the ocean is concisely related in a volume that focuses on Alvin, the submersible vehicle used to map undersea mountain ranges, examine hydrothermal vents, and find the Titanic. The text also touches on more recent developments involving remote operated vehicles and their potential for future underwater exploration. The text is clear; the color photos only sometimes are. Bib., glos., ind.

(4) 4-6 Turnstone Ocean Explorer Book series. This account tracing the development of a theory for the K/T mass extinction (the one that wiped out the dinosaurs) is written by a researcher involved in the search for an explanation. Important clues from the fossil record, the field, and experimental studies provide compelling evidence for a meteorite impact and insights into the complexity of scientific research. Color photographs and illustrations are interesting but grainy. Bib., glos., ind.
