Phytoplankton aggregations come in a wide range of space and time scales and, as such, simulating such behavior is computationally restrictive. I present a Large-eddy simulation of the upper mixed layer, resolving scales of o(1m). I then show how aggregations are promoted by nutrient upwellings (something which macroscale models struggle to emulate), facilitated primarily by Langmuir circulations. I then demonstrate how certain levels of turbulent mixing encourage planktonic thin layering, a phenomenon which is widely observed.
