Chemical Dispersants and Their Role in Oil Spill Response

Learn why and how dispersants are used during oil spills and how they were used during the Deepwater Horizon oil spill.

Fate, Transport and Effectiveness of Dispersants Used in the Deepwater Horizon Oil Spill

Learn about the effectiveness and persistence of dispersants in the environment and whether it was necessary to use dispersants at the subsurface.

Responses of Aquatic Life in the Gulf of Mexico to Oil and Dispersants

Learn how dispersants impact aquatic life in terms of life stage and species, and how lab and field studies can provide a more complete picture of the implications of exposure to oil and dispersants.


We’ve also posted the recordings of recent Sea Grant seminars that focus on dispersants:


Beyond the response: A look at the science and policy behind dispersants


Understanding the toxicity of oil and dispersant mixtures, and the development of alternative dispersants


Bridging the gap between oil spill researchers and responders


Healthy Gulf seafood


We are continuously working to bring you oil spill science, so please stay tuned for our upcoming publications and science seminars. Please be sure to check out our other oil spill outreach publications: and listen to the recordings of past seminars:
