During a 35-year career at Scripps, Dayton has researched coastal Antarctic habitats and the rocky shore habitats of Washington in order to better understand marine ecosystems. He has also documented the environmental impacts of overfishing, and phenomena such as El Niño on coastal ecology.

Dayton is the only person to win both the George Mercer Award (1974) and the WS Cooper Award (2000) from the Ecological Society of America. In 2002, he received the Scientific Diving Lifetime Achievement Award from the American Academy of Underwater Sciences; in 2004 he was honored with the Edward O. Wilson Naturalist Award from the American Society of Naturalists, and in 2006 was the first recipient of the Ramon Margalef Prize in Ecology.
