Oceanography

Throughout Earth’s history, oceanic composition and marine life have served as primary controls on the evolution of the atmosphere and global climate. Oceanography is a multidisciplinary field dedicated to decoding the physical, chemical, and biological mechanisms that govern the ocean's state. By understanding how the ocean functions as a system, scientists can reconstruct past climate records and define the fundamental laws that maintain Earth’s habitability.

Researchers in our department investigate oceanography with a specific emphasis on biogeochemical cycling and the origins and early evolution of life. We utilize a multi-scale approach that integrates field observations with high-resolution laboratory analysis to bridge the gap between microscopic processes and global-scale environmental shifts. Ultimately, the study of oceanography at Ben-Gurion University of the Negev provides an integrated understanding of the complex biogeochemical processes that have controlled Earth's habitability throughout its history and continue to influence our global environment today.
