Summary

This dataset (in ESRI file geodatabase format) contains inundation areas for various future scenarios of sea-level rise (SLR), groundwater rise, and storm waves at Midway Atoll in the Northwestern Hawaiian Islands. Four types of inundation scenarios are considered: (1) passive SLR, (2) passive SLR including groundwater rise, (3) wave-driven inundation during storm events, and (4) wave-driven inundation during storm events including groundwater rise. For each of these four scenarios, five different levels of SLR are considered: 0.00 m, +0.50 m, +1.00 m, +1.50 m, and +2.00 m. We considered each scenario at mean high water in order to predict inundation during the more damaging part of the tidal range. Each of the above types of inundation [...]

Purpose

The purpose of these GIS inundation layers is to forecast the impacts of rising sea level, rising groundwater level, and storm waves on seabirds and their habitat at Midway Atoll for a range of sea-level rise scenarios from 0 to 2 meters. The impacts to seabirds and seabird habitat can be estimated by overlaying the inundation layers in this dataset with seabird distribution and abundance data, generally available from the U.S. Fish and Wildlife Service.
