Stephen E. (Steve) Calvert, PhD, FRSC (born December 30, 1935) is a professor emeritus at the University of British Columbia. He has specialized in the study of chemical and geochemical oceanography. His work has shed light on the factors responsible for the wide compositional variability of marine sediments, the controls on organic matter burial and nutrient utilization in the ocean.

Calvert utilizes a combination of organic, inorganic and stable isotopic information to reconstruct past sea surface temperatures, plankton production, terrestrial sediment supply and transport modes, nutrient utilization and bottom water oxygen concentrations.
Early life and career
editCalvert was born in London, England in 1935. He studied at the University of Reading, obtaining a bachelor of science degree in 1958. Later, he emigrated to Canada, where he received his Ph.D. from Scripps Institution of Oceanography in 1964. Calvert is also a member of the UCSD Alumni Association. Currently, Calvert is a professor emeritus at the University of British Columbia.
