Polona Itkin


Researcher / Earth Observation

Job description

Research Summary

Dr. Itkin specializes in studying sea ice motion and mass balance of sea ice and snow. In her work she combines data from in-situ observations, numerical models, and satellite and airborne remote sensing products. Her latest focus has been sea ice deformation and its impact on the distribution of sea ice and snow. She is the project manager of the Young Research Talent project funded by the Norwegian Research Council: Sea Ice Deformation and Snow for an Arctic in Transition (SIDRiFT), running 2019-2023.
