Crude oil or oil distilled product (e.g. gasoline, diesel fuels, jet fuels) spills can occur during oil exploration, production, and transportation activities. Environmental impacts of spills are complex and can be difficult to assess. The chemical makeup of oil and oil products is diverse which affects oil behavior (e.g. volatilization, sinking). Oil degradation and fate are also influenced by environmental factors such as salinity, temperature, and surface vs underground spills. Oil can impact living organisms both directly (dermal contact, inhalation, ingestion) and indirectly (bioaccumulation in food sources, disruption of recreational activities). USGS scientists have decades of experience supporting assessment and restoration activities for the largest oil spills in U.S history, Exxon Valdez Oil Spill and Deepwater Horizon Oil Spill. Examples include oil spill remote sensing, vegetation surveys, ecotoxicological impacts, marsh ecology impacts, sea turtle modelling, immunosuppression of oiled biota, coral ecology, and avian and mammalian injury and recovery.
