NZ MetOcean and University of Otago PhD student, Phellipe Couto will have his work cut out for him to model and understand the multi-scale dynamics of these fronts, streaks and eddies. Not shown in these pictures is a large submarine canyon that sits beneath the surface and extends all the way to the coastline. Fun stuff!
