Theodore J. Smayda (1931[1] – April 5, 2017) was an American oceanographer.
He was born in Peckville, Pennsylvania. He was employed at the University of Rhode Island in 1959. He later won a Fulbright Scholarship to travel to Norway and study at the University of Oslo, where he took the dr.philos. degree.[2][3] His defense of his doctoral thesis took place in the Norwegian language. The thesis regarded phytoplankton in the Panama Gulf; the opponents were Trygve Braarud and Odd Henrik Sælen.[4] Following his stay in Norway, Smayda returned to the University of Rhode Island where he served as a professor of oceanography throughout his career.[2]
He was a fellow of the Norwegian Academy of Science and Letters from 1992.[1] Limnology & Oceanography found his article "Harmful algal blooms: Their ecophysiology and general relevance to phytoplankton blooms in the sea" to be one of the top 60 most cited between 1956 and 2016.[5]
He was married and resided in Jamestown, Rhode Island. He died in April 2017 at the age of 85.[3]
