Summary
This data release consists of two ESRI geodatabases that store inundation areas for various future scenarios of sea-level rise (SLR), groundwater rise, and storm waves for Laysan Island and Midway Atoll in the Northwestern Hawaiian Islands. Five types of inundation scenarios are considered: (1) passive SLR, (2) passive SLR including groundwater rise, (3) wave-driven inundation during storm events, (4) wave-driven inundation during storm events including groundwater rise, and (5) wave-driven inundation during storm events, assuming unlimited seawater volumes and no infiltration (i.e., theoretical maximum). This scenario applies only to Laysan Island which has topographic depressions that fill with water during flood events. For each [...]
Summary
This data release consists of two ESRI geodatabases that store inundation areas for various future scenarios of sea-level rise (SLR), groundwater rise, and storm waves for Laysan Island and Midway Atoll in the Northwestern Hawaiian Islands. Five types of inundation scenarios are considered: (1) passive SLR, (2) passive SLR including groundwater rise, (3) wave-driven inundation during storm events, (4) wave-driven inundation during storm events including groundwater rise, and (5) wave-driven inundation during storm events, assuming unlimited seawater volumes and no infiltration (i.e., theoretical maximum). This scenario applies only to Laysan Island which has topographic depressions that fill with water during flood events. For each of these 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 have their own feature dataset within the geodatabase, named as follows: (1) Passive, (2) PassiveGW, (3) WaveDriven, (4) WaveDrivenGW, and (5) WaveDriven_TheoreticalMax (applies to Laysan Island only). Each of these feature datasets contains five feature classes labeled in a manner that indicates the SLR scenario under consideration. For instance, within the dataset "Passive", there are five feature classes: Passive_SLR_00cm, Passive_SLR_50cm, Passive_SLR_100cm, Passive_SLR_150cm, and Passive_SLR_200cm.

Berkowitz, P., Storlazzi, C.D., Courtot, K.N., Krause, C.M., and Reynolds, M.H., 2012, Sea-level rise and wave-driven inundation models for Laysan Island, Chap. 2 of Reynolds, M.H., Berkowitz, P., Courtot, K.N., and Krause, C.M., eds. Predicting sea-level rise vulnerability of terrestrial habitat and wildlife of the Northwestern Hawaiian Islands: U.S. Geological Survey Open-File Report 2012-1182, p. 72–126.
The purpose of these two geodatabases is to help forecast the impacts of rising sea level, rising groundwater level, and storm waves on seabirds and their habitat at Laysan Island and 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 various inundation layers included in these geodatabases with seabird distribution and abundance data (generally available from the U.S. Fish and Wildlife Service). The Northwestern Hawaiian Islands represent one of the most important breeding areas in the world for seabirds, and consequently is an area of major interest to biologists.
