Harold V. Thurman." Hal Thurman retired in May 1994, after 24 years of teaching in the Earth Sciences Department of Mt. San Antonio College in Walnut, California. Interest in geology led to a bachelor's degree from Oklahoma A & M University, followed by seven years working as a petroleum geologist, mainly in the Gulf of Mexico, where his interest in the oceans developed. He earned a master's degree from California State University at Los Angeles and then joined the Earth Sciences faculty at Mt. San Antonio College. Other books that Hal has coauthored include "Essentials of Oceanography" (with Alan Trujillo) and a marine biology textbook. He has also written articles on the Pacific, Atlantic, Indian, and Arctic Oceans for the 1994 edition of "World Book Encyclopedia" and served as a consultant on the National Geographic publication, "Realms of the Sea." He still enjoys going to sea on vacations with his wife Iantha.

A1 began teaching in the Earth Sciences Department at Palomar in 1990 and in 1997 was awarded Palomar's Distinguished Faculty Award for Excellence in Teaching. He has coauthored "Essentials of Oceanography" with Hal Thurman and is a contributing author for other Earth science textbooks, including "Earth,"7th edition and "Earth Science," 10th edition.
