Dr. Ivy Frenger

Research Scientist at Research Unit Biogeochemical Modelling.

My overall objectives are to contribute to a better understanding of the climate system and its response to anthropogenic forcing. My research focuses on  (i) characteristics and effects of ocean mesoscale eddies, (ii) oceanic biophysical and ocean-atmosphere interactions, (iii) the Southern Ocean in a changing climate and (iv) the ocean carbon cycle. My research is based on ocean models, satellite and in situ data.
