Seabird Oil Sensitivity Index (SOSI)

What is it: 

The Seabird Oil Sensitivity Index (SOSI) is a tool which aids planning and emergency decision making with regards to oil pollution. It identifies areas at sea where seabirds are likely to be most sensitive to oil pollution. It is based on seabird survey data collected from 1995 to 2015, from a wide survey area extending beyond the UK Continental Shelf using boat-based, visual aerial, and digital video aerial survey techniques.

There are 2 layers each with the 12 months of the year included (months are numbered 1 - 12 rather than named):

  • Median sensitivity of seabird concentrations to oil pollution in DECC Offshore Oil Licence Blocks by month (time-aware).
  • Confidence in the assessment of sensitivity of seabird concentrations to oil pollution in DECC Offshore Oil Licence Blocks by month (time-aware).
