Featured Data Layer

Environmental Sensitivity Index (ESI) maps serve as quick references for oil and chemical spill responders and coastal zone managers. They contain three kinds of information:

  • Shorelines are ranked based on their physical and biological character, then color-coded to indicate their sensitivity to oiling.
  • Sensitive biological resources, such as seabird colonies and marine mammal hauling grounds, are depicted by shaded polygons and symbol icons to convey their location and extent on the maps.
  • ESI maps also show sensitive human-use resources, such as water intakes, marinas, and swimming beaches.
