The project uses models along with a coastal circulation model coupled with wave and sediment models to provide a holistic description for the physical behavior of oil from the inner shelf through the surf zone. In particular, an OPA model developed by one of the PIs will be integrated with the coastal circulation model within a Lagrangian-Eulerian framework serving to provide estimates of OPA formation throughout these zones. These studies will (1) identify zones within the Langmuir supercells where mixing between oil droplets and sediments can occur and establish residence times of sediments and oil droplets within these zones, (2) characterize the mixing energy (i.e. the turbulent kinetic energy) within these zones, and (3) measure the coagulation efficiency of interactions between oil and sediment particles. Overall, these experiments will allow extension of the OPA model to the surf-shelf transition zone in inner shelves where Langmuir supercells are expected to occur.
