In 1940 Steinbeck sailed in a sardine boat with his great friend the marine biologist, Ed Ricketts, to collect marine invertebrates from the beaches of the Gulf of California. The expedition was described by the two men in Sea of Cortez, published in 1941. The day-to-day story of the trip is told here in the Log, which combines science, philosophy and high-spirited adventure.

Log from the Sea of Cortez includes the narrative of the journey and the essay “About Ed Ricketts.” It does not include pictures and detailed descriptions of the species collected by Steinbeck and Ricketts. (See also Sea of Cortez.)
