ABSTRACT
Each marine oil spill presents unique circumstances and challenges that require careful consideration of which response options are most appropriate for mitigating impacts to local communities and the environment, which may include the use of dispersants. Dispersants are chemical countermeasures that reduce the amount of floating oil by promoting the formation of small droplets that remain or become entrained in the water column, where they are subjected to greater dissolution and dilution. During the Deepwater Horizon oil spill, an unprecedented volume of dispersants was used at the surface and in the deep ocean. The spill stimulated interest and funding for research on oil spill science, especially regarding dispersant use. Building on two previous reports and using this new information, a committee of experts convened by the National Academies of Sciences, Engineering, and Medicine (NASEM) conducted a review and evaluation of the science on dispersant use. The committee's review focused on various aspects of dispersant use in offshore marine oil spills, including dispersant and oil fate and transport, human health considerations, biological effects, decision making, and alternative response options, among others. The findings and recommendations of the committee were published in the recent report, The Use of Dispersants in Marine Oil Spill Response (available for free download at https://www.nap.edu/catalog/25161/the-use-of-dispersants-in-marine-oil-spill-response). The presentation summarizes the committee's findings and recommendations within the context of oil spill response science and technology. A key area of consideration is how they relate to and support a robust decision making process in the event dispersants are considered for use in future spills.
