Using the Seabird Oil Sensitivity Index to inform contingency planning 2018
The Oil Vulnerability Index (OVI) (JNCC 1999) has been updated using recent survey data (from 1995-2015) and includes an improved method to calculate a single measure of seabird sensitivity to oil pollution. This new index (named the Seabird Oil Sensitivity Index or ‘SOSI’) identifies areas at sea where seabirds are likely to be most sensitive to oil pollution. It is intended to be employed by a range of users to inform contingency planning and emergency decision making with regards to oil pollution incidents.
The quantity of data underlying the SOSI is considerably lower than that of the previous OVI. This has resulted in the SOSI having poor coverage in some months. Coverage gaps may cause issues when users try to obtain seabird sensitivity information for Oil and Gas Licence Blocks that lack data. This document provides guidance on how those gaps can be populated in order to inform environmental statements, oil pollution emergency plans and other environmental applications.
