Environmental vulnerability index:
A location and season specific index for environmental vulnerability of marine resources with respect to oil spill as external stressor. The vulnerability assessment was performed for the different ecological uses in about 100 areas of heightened ecological significance within the 17 Arctic Large Marine Ecosystems.
The Safety and Operability Index (SOI)
is developed from the data in the Arctic Risk Map. The SOI is based on risk influencing factors such as sea ice, visibility, temperature, distance from SAR resources etc, and gives an aggregated score for each Arctic region for factors that are identified to affect safety and operability in these regions, and also compared with a benchmark. The benchmark is chosen to be operations in the Norwegian Sea.
