Wallace J. Nichols (1967 - June 10, 2024) was a marine biologist who is known as the author of Blue Mind and other significant works, as well as promoting several marine improvement ventures.
He studied marine biology in the early 1990s, before completing his PhD at the University of Arizona, Tucson, where he specialized in turtle genetics, migration and conservation. He and his colleagues famously tagged a loggerhead turtle named Adelita, and tracked it by satellite as it swam from California to Japan – this was the first animal to be recorded crossing an entire ocean basin.
