The long term goal of this project is to develop a better understanding of oceanic processes in the range of 100 m to 10 km, in the so-called submesoscale range. In particular, it is important to explore and find out whether and what type of submesoscale instabilities exist, how they are connected to both larger scale and smaller scale motions, and to what extent they influence transport processes in the ocean. Another important objective of this project is to test how well subgrid-scale SGS models for large eddy simulations LES work in the presence of backward energy cascade that may be characteristic in submesoscale motions. Another long term objective of this effort would be to improve the predictive skill of the Navy numerical models for submesoscale transport in the ocean. My main objective has been to model upper ocean mixed layer instabilities, investigate their behavior and try to develop sampling strategies using synthetic drifters and tracers prior to the first LatMix cruise. In addition, I have put in a significant effort during the first LatMix cruise that took place in June 2011.
