Modeling Water Column Oil Concentrations with a Lagrangian Element Oil Spill Model (GNOME)
Prediction of water column concentrations is sensitive to a number of factors that are not typically well known or understood. These include: the turbulence profile of the water column, the droplet size distribution of oil under the surface, and oil entrainment rates under white-capping seas. Here we review the challenges of modeling oil concentrations in the water column in general, and specifically the challenges of using a Lagrangian element approach. The results of various assumptions are explored with a sensitivity analysis and compared against oil concentrations measured in the field.
