I am a PhD candidate at the theory and modeling department of the GEOMAR Helmholtz Centre for Ocean Research Kiel (Germany), working on Lagrangian connectivity in the eddying ocean. I am studying the exchange pathways, timescales and transports between distinct oceanic regions by simulating the dispersal of virtual fluid particles in high-resolution eddy-resolving ocean models.
Currently, I am addressing the question of the relative importance of waters with Pacific Ocean origin versus waters with Indian Ocean origin for the northward flow and heat transport of the upper limb of the Atlantic meridional overturning circulation.
The poster I presented was about Lagrangian eddy diffusivity estimates, which quantify the rate of particle dispersal due to turbulent processes, showing how diffusive the dispersal of simulated particles is compared to observed surface drifter dispersal.
