Instructor's Manual for Essentials of Oceanography (Available via Mastering)

About our authors Al Trujillo is a Distinguished Teaching Professor in the Earth, Space, and Environmental Sciences Department at Palomar College in San Marcos, California. He received his bachelor’s degree in geology from the University of California at Davis and his master’s degree in geology from Northern Arizona University, afterward working for several years in industry. Al began teaching at Palomar in 1990. In 1997, he was awarded Palomar’s Distinguished Faculty Award for Excellence in Teaching, and in 2005 he received Palomar’s Faculty Research Award. He has coauthored Introductory Oceanography with Hal Thurman and is a contributing author for the textbooks Earth and Earth Science. In addition to writing and teaching, Al works as a naturalist and lecturer aboard Holland America Line and natural history expedition vessels for Lindblad Expeditions/National Geographic in Alaska, Iceland, the Sea of Cortez/Baja California, and the South Pacific. His research interests include beach processes, sea cliff erosion, and active teaching techniques. He enjoys photography, and he collects sand as a hobby. Al and his wife, Sandy, have two children, Karl and Eva. Hal Thurman’s 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. Hal began teaching at Mt. San Antonio College in Walnut, California, in 1968 as a temporary teacher and taught Physics 1 (a surveying class) and three Physical Geology labs. In 1970, he taught his first class of General Oceanography. It was from this experience that he decided to write a textbook on oceanography and received a contract with Charles E. Merrill Publishing Company in 1973. The first edition of his book Introductory Oceanography was released in 1975. Harold authored or coauthored over 20 editions of textbooks that include Introductory Oceanography, Essentials of Oceanography, Physical Geology, Marine Biology, and Oceanography Laboratory Manual, many of which are still being used today throughout the world. In addition, he contributed to the World Book Encyclopedia on the topics of “Arctic Ocean,” “Atlantic Ocean,” “Indian Ocean,” and “Pacific Ocean.” Hal Thurman retired in May 1994, after 24 years of teaching, and moved to be closer to family in Oklahoma, then to Florida. Hal passed away at the age of 78 on December 29, 2012. His writing expertise, knowledge about the ocean, and easy going demeanor are dearly missed.
