James Zachos

James C. Zachos (* 1959 ) is an American oceanographer whose main research areas are palaeoceanography and paleoclimatology . He has been Professor of Earth and Planetary Sciences at the University of California, Santa Cruz since 2000 . Zachos is one of the world's most important researchers in the field of palaeoceanography and paleoclimatology.

Live and act

After completing a bachelor's degree in 1981 from the State University of New York and a master's degree from the University of South Carolina in 1984 , Zachos began a doctoral degree in oceanography at the University of Rhode Island , which he obtained in 1988 with a Ph.D. successfully completed. He then worked as a postdoc and later as an Assistant Research Scientist at the University of Michigan before moving to the University of California in 1992. There he worked initially as an assistant professor and later as an associate professor. In 2000 he was finally appointed professor to the chair in the Department of Earth and Planetary Sciences.

His research interests include the mechanisms behind the long and short term changes in the world's climate throughout the history of the earth. Among other things, he deals with the chemical analysis of shell fragments from sediment layers, with which he u. a. historical changes in ocean temperatures and ocean currents, the ice cover of continents and carbon fluxes tries to fathom.

His h-index was 83 in September 2019.

Awards (selection)

He has received numerous awards for his research. Among other things, he received the Milutin Milankovic Medal from the European Geosciences Union and was elected a member of the American Academy of Arts and Sciences and the National Academy of Sciences .
