Dirk Notz is a professor at the University of Hamburg, where he leads the Sea Ice research section within the Institute of Oceanography. His work focuses on understanding the dynamics of sea ice and its interactions with the climate system. He has contributed to numerous studies addressing the implications of climate change on polar regions, employing advanced modeling techniques and observational data to further our understanding of sea ice processes. A key part of his role includes being the Deputy Managing Director of the Institute of Oceanography, overseeing research initiatives and collaboration within the field. Through his research, Notz aims to improve climate predictions and to analyze the complex feedback mechanisms that govern sea ice behavior in a warming world.
