We are proud to announce the successful disputation of our SICSS member Aurpita Saha.
Her dissertation "Barrier layers in the tropical Atlantic Ocean: Growth and decay mechanisms and impact of Amazon river runoff" was supervised by Prof. Dr. Detlef Stammer and Dr. Nuno Serra.
Aurpita investigated the freshwater changes and the underlying processes in the northern tropical and subtropical Atlantic Ocean by analyzing daily outputs of high-resolution eddy-resolving numerical simulations of the Atlantic Ocean using MITgcm. The impacts of small-scale ocean processes like eddies and fronts embedded in the regional circulation, on the evolution of barrier layers i.e. stratification in the upper-ocean were investigated. Aurpita identified and quantified the growth and decay mechanisms of the barrier layers in the tropical Atlantic Ocean. Moreover, with numerical sensitivity experiments, she explored the impacts of extreme and realistic changes in the Amazon river discharge on the northern tropical Atlantic ocean circulation and upper-ocean barrier layers.
Aurpita was a member of the Institute of Oceanography at the Universität Hamburg.
