The Automated Data Inquiry for Oil Spills (ADIOS2) software is an oil weathering model provided by NOAA that incorporates a database containing more than a thousand crude oils and refined products, and provides quick estimates of the expected characteristics and behavior of oil spilled into the marine environment. The predictions it makes, presented as both graphics and text, are designed to help answer questions that typically arise during spill response and cleanup. For example,

• By predicting change in an oil's viscosity (resistance to flow) over time, ADIOS2 offers an answer to the question: Can the oil still be dispersed with chemical dispersants?
• By predicting the rate of increase in an oil's water content over time, ADIOS2 offers an answer to questions like: If 1000 gallons (3,785.4 l) of crude oil has spilled, will more than 1000 gallons (3,785.4 l) of oil-and-water mixture need to be cleaned up and disposed of? How much more?

Prominent Uses

• On May 14, 2010, the AP reported that this tool is being used to help assess where all the oil is going from the Deepwater Horizon Oil Spill
  Deepwater Horizon oil spill
  The Deepwater Horizon oil spill is an oil spill in the Gulf of Mexico which flowed unabated for three months in 2010, and continues to leak fresh oil. It is the largest accidental marine oil spill in the history of the petroleum industry...
