摘要: Subsea dispersant injection (SSDI) was a new oil spill response (OSR) technology deployed during the Deepwater Horizon accident. To integrate SSDI into future OSR decisions, hypothetical deepwater to Gulf of Mexico simulated and comparative risk assessment (CRA) tool applied contrast three strategies: (1) no intervention; (2) mechanical recovery, in-situ burning, surface dispersants; and, (3) in addition responses (2). A ecological multiple valued ecosystem components (VECs) inhabiting different environmental compartments (ECs) using EC-specific exposure relative VEC population density recovery time indices. Results demonstrated added benefit since risks shoreline, wildlife most aquatic life VECs were reduced. Sensitivity results assumptions also tested illustrate flexibility CRA addressing stakeholder priorities for mitigating impacts blowout.
