Abstract:

This dataset contains simulations run with Texas A&M Oilspill Calculator (TAMOC) including biodegradation for a deep-sea blowout. Simulations published in the associated publication, Socolofsky et al., (2019). Authors reviewed existing algorithms and rates and conducted a model sensitivity study. All deep-sea blowout simulations were conducted at 2000 m depth and were either treated with sub-surface dispersant injection (2% dispersant to oil ratio) or untreated. For the model sensitivity study, a total of 32 sensitivity simulations were run, using two oils types and four different sets of first-order decay rates varying the biodegradation constant, with and without sub-surface dispersant injection and with and without lag time for onset of biodegradation. This dataset supports the publication: Socolofsky, S. A., Gros, J., North, E., Boufadel, M. C., Parkerton, T. F., & Adams, E. E. (2019).
