Hawaiian Islands Hawaiian Hoary Bat Genetic Sexing 2009-2018

We tested the utility of a protocol using genetic markers that previously proved successful to identify the sex of Vespertilionid bats on tissues collected from live bats and carcasses of varying age from the Hawaiian hoary bat (Lasiurus cinereus semotus). This molecular method is based on genes unique to X and Y chromosomes in mammals and previously was used successfully on North American...

Oahu multi-state occupancy models of foraging habitat use by Hawaiian hoary bats 2017

This data release consists of a single table that includes sample site geographic locations, insect prey abundance, and bat activity and behavior metrics. The dataset was used to develop multi-state occupancy models of foraging habitat use by Hawaiian hoary bats (Lasiurus cinereus semotus).

Northwestern Hawaiian Islands: Impacts to Avifauna from the Tohoku Tsunami 2011

This collection of nine datasets covers Midway Atoll and Laysan Island in the Northwestern Hawaiian Islands, and was created to help estimate the impacts of the March 11, 2011 tsunami event on avifauna in the Northwestern Hawaiian Islands.

Northwestern Hawaiian Islands Sea-level Rise Scenarios and Models 2010-2015

This data release consists of two ESRI geodatabases that store inundation areas for various future scenarios of sea-level rise, groundwater rise, and storm waves for Laysan Island and Midway Atoll in the Northwestern Hawaiian Islands.

Northwestern Hawaiian Islands Sea-level Rise Scenarios and Models 2010-2015

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...

Laysan Island landcover 18May2010

This dataset contains landcover classes for Laysan Island based on a satellite image taken by DigitalGlobe, Inc. on May 18, 2010. Landcover was classified into 15 different categories, categories determined by how avifauna use these categories for habitat, nesting and foraging.

Laysan Island coastline 2010May18

This dataset contains a screen-digitized coastline for Laysan Island based on a DigitalGlobe WorldView-2 satellite image taken on May 18, 2010. After digitization the coastline was corrected for tide using a 1-meter digital elevation model (DEM). It was also smoothed in ArcGIS 10 to remove some of the inherent jaggedness from the point-by-point digitizing process. Like most of the Northwestern...

Midway Atoll inundation area during the 2011 tsunami

This polygon layer delineates the area inundated during the March 11, 2011 tsunami. It is based on a tracking file generated by Pete Leary, of US Fish and Wildlife Service, who traversed the high water mark (debris line) of the tsunmai on March 15, 2011. The coastline at Midway Atoll, which changes from year to year and season to season, was taken from the last available image (Jan. 14, 2010)...

Northwestern Hawaiian Islands: Impacts to Avifauna from the Tohoku Tsunami 2011

This collection of nine datasets covers Midway Atoll and Laysan Island in the Northwestern Hawaiian Islands, and was created to help estimate the impacts of the March 11, 2011 tsunami event on avifauna in the Northwestern Hawaiian Islands. For each island, we generated a coastline dataset and a land cover dataset based on satellite imagery taken the year before the tsuanmi event. We also...
