Bristol Bay Alaska Coastal Sensitivity Maps for Spill Response

NOAA's Environmental Sensitivity Index (ESI) Atlas for Bristol Bay, Alaska, provides standardized maps and data for coastal shoreline sensitivity, biological resources, and human-use resources. The dataset is designed to identify sensitive environments before a spill to establish protection priorities and design cleanup strategies. It was created by NOAA and last updated in 2004.

Use Cases

• Prioritize shoreline protection based on mapped shoreline sensitivity classifications during an oil spill event.
• Identify critical biological habitats by overlaying mapped biological resource data with spill trajectory models.
• Plan cleanup strategies by analyzing the spatial distribution of human-use resources like recreational areas or fisheries.
• Assess coastal vulnerability by integrating ESI shoreline types with physical exposure data for climate adaptation studies.

Strengths

• Based on the NOAA ESI methodology, the most widely used approach for sensitive environment mapping in the United States.
• Compiles three standardized data categories: coastal shoreline sensitivity, biological resources, and human-use resources.

Limitations

• Data is temporally stale, with a last update in 2004, potentially missing recent environmental changes.
• Geographic scope is limited to the Bristol Bay region of Alaska, not nationally comprehensive.
