Stefanie Leonore Ypma

Stefanie is currently working as a PhD candidate at Delft University of Technology. Her research is focused on the formation and spreading of dense watermasses in the Nordic Seas. The aim is to shed more light on the connection between ocean dynamics (like deep convection, boundary current instability and frontal processes) and changes in environmental conditions. A Lagrangian approach is applied to study pathways and characteristics of different watermasses in both global models as in a high-resolution regional idealised model. More information on recent findings and publications can be found below.

Stefanie has obtained her bachelor’s degree in Physics at Leiden University and her master’s degree in Physical Oceanography at Utrecht University. During her master research she studied the separation of the East Australian Current at the Climate Change Research Centre in Sydney, Australia. She also enjoys playing music and getting lost in nature.
