Susan Lozier

Susan Lozier is a Professor of Physical Oceanography at Duke University since 1992, holding the rank of Distinguished Professor. She serves as past-president of The Oceanography Society and leads the OSNAP observing system. Her research focuses on large-scale ocean circulation, climate dynamics, and subpolar North Atlantic processes.

Education:

• Ph.D., University of Washington (1989)
• B.S., Purdue University (1979)

Research Interests: Dr. Lozier investigates ocean circulation patterns, particularly in the subpolar North Atlantic, using observational and theoretical approaches. She leads OSNAP, a multinational project measuring overturning circulation and water mass transformation. Her work bridges climate science and ocean dynamics, emphasizing the role of ocean currents in global climate systems.

Awards:

• NSF Early Career Award (1996)
• Bass Chair for Excellence in Research and Teaching (2000)
• American Meteorological Society Fellow (2008)
• AGU Fellow and former AGU President (2014–2021)
• AAAS Fellow (2015)

Grants & Advising: Recent grants include NSF-funded studies on North Atlantic deep-water pathways and overturning circulation dynamics. She advises projects involving nonlinear dynamics and satellite-based ocean observation.

Labs/Teams: Oversees the OSNAP project as international lead, integrating data from moorings and floats to map oceanic overturning processes.
