Environmental Sensitivity Index

NOAA Office of Response and Restoration

Details

  • Environmental Sensitivity Index (ESI) maps and data are updated as long as funding is available
  • Updates in progress:
    • Florida – south (expected completion May 2013)
    • Louisiana (expected completion July 2013)
    • Upper coast of Texas (expected completion July 2013)
    • Delaware Bay (expected completion January 2014)
    • Washington and Oregon outer coast (expected completion July 2014)

Notes and Limitations: ESIs are developed in the context of oil spill planning and response. They are useful for many other applications, but users should recognize the limitations this context imposes. In particular, ESIs are not intended to be an inventory of biological resources, but they instead focus on species more susceptible or sensitive to oiling, areas of high concentrations, threatened and endangered species, and areas where sensitive life stages are found.
