What is ADIOS2?
Automated Data Inquiry for Oil Spills (ADIOS2) is
an initial oil spill response tool for emergency
spill responders and contingency planners.

Oil Weathering Models

• Evaporation (less than 5 days)
• Dispersion (less than 5 days)
• Dissolution (less than 5 days)
• Emulsification (Onset can be delayed for days but
  the emulsification process happens rapidly)
• Sedimentation (5 days or more)
• Photo-oxidation (weeks)
• Biodegradation (weeks to months)

5
Spreading in ADIOS2

• Modification of Fays formula (gravity inertia
  and gravity viscous spreading)
• Winds and currents
• Particles are used to simulate changing oil
  volumes
• Thiessian polygons used to calculate surface area
• Results in slick with varying thickness and
  surface coverage

6
Evaporation

• Pseudo-component evaporation model
• More demanding data requirements than ADIOS1
  (e.g., distillation data)
• Correlation techniques used for missing data

7
Dispersion

• Delvignes dispersion model
• User specified chemical dispersion
• New sub-model for breaking waves
• New options regarding fetch specifications

8
Emulsification

• Water droplet surface area as well as volume
  calculations
• Includes several options for determining onset of
  emulsification

9
Sedimentation

• Paynes first order rate law
• Included in dispersed oil mass balance
  calculations

A) 10,000 g/m3 B) 1000 g/m3 C) 100
g/m3 D) 10 g/m3 E) 1 g/m3

Benzene

• Calculates airborne benzene concentrations at
  downwind edge of slick
• Correlation techniques for missing data in crude
  oils
