For my PhD in Arctic oceanography I worked with my supervisors Prof. Louis Fortier and Prof. Marcel Babin at the Takuvik Joint International Laboratory (CERC in Remote Sensing of Canada’s New Arctic Frontier), Université Laval, Québec, Canada.
There, I worked on the spatiotemporal variability of mesozooplankton and coupling with their phytoplankton food in the Canadian Arctic. To reach my study goals I utilized a new optical underwater imaging system (Lightframe Onsight Keyspecies Investigation, LOKI) and machine learning algorithms. I developed an automatic species recognition model, down to the developmental stage of species, which can reliably turn images into taxonomic information. I then used that model to further work on the links between individual copepod lipids and the copepods’ diapause. As part of my PhD I also described intriguing fine vertical scale (1 m resolution) Calanus species interactions. Calanus hyperboreus showed substantially different distribution peaks, in the subsurface chlorophyll maximum, from C. glacialis. The findings of my PhD are described in three research papers listed in the publications section.
For my M.Sc. thesis in International Nature Conservation I worked on spatial predictive modeling of pan-Arctic zooplankton. I used present time and future environmental data to predict zooplankton parameters like depth distribution and presence/absence into the future (max. year 2100). Future data was taken from the Canadian Earth System Model 2 (CanESM2), 5th generation IPCC data. I did this work at the University of Alaska Fairbanks
