Congratulations to University of Otago PhD student, Rafael Costa Santana! Almost 3 years to the day that he began his PhD research, Rafa has submitted his thesis for evaluation. Rafa has been remarkably efficient in being able to use ocean observations, and apply data assimilation techniques to better understand transport and variability of the East Auckland Current. He continues on with a post-doc at the University of Auckland and is sure to have many terrific future opportunities.
