Multi-Hazard Inundation: Honolulu, Hawaii

Multi-hazard inundation around Honolulu. The study area includes the urban corridor stretching from Honolulu International Airport to Waikiki and Diamond Head along the south shore of Oahu. Shows inundation from the following two hazards:

1) Tsunami Run-Up Inundation

Computer model simulation of tsunami run-up inundation using current sea level at mean higher high water (MHHW) as its baseline water level. The model simulates maximum inundation based on five major historical tsunamis that have impacted Hawaii: 1) The 1946 Aleutian earthquake (8.2 Mw), 2) 1952 Kamchatka earthquake (9.0 Mw), 3) 1957 Aleutian earthquake (8.6 Mw), 4) 1960 Chile earthquake (9.5 Mw), and 5) the 1964 Alaska earthquake (9.2 Mw).

2) Hurricane Storm Surge Inundation

Computer model simulation of hurricane storm surge inundation using current sea level at mean higher high water (MHHW) as its baseline water level. The model simulates a Category 4 hurricane, similar to Hurricane Iniki which devastated the island of Kauai in 1992, with a central pressure ranging from 910 to 970 mbar and maximum sustained winds ranging from 90 to 150 mph as it tracked from open ocean to land to open ocean again. The model result shows the Maximum of the Maximum Envelope of High Water (MEOW), or MOM, providing a worst-case snapshot for a particular storm category under "perfect" storm conditions.

Data produced in 2014 by Dr. Kwok Fai Cheung of the department of Ocean and Resources Engineering (ORE) in the School of Ocean and Earth Science and Technology (SOEST) of the University of Hawaii at Manoa. Supported in part by the NOAA Coastal Storms Program (CSP) and the University of Hawaii Sea Grant College Program. While considerable effort has been made to implement all model components in a thorough, correct, and accurate manner, numerous sources of error are possible. The entire risk associated with the results and performance of these data is assumed by the user. These data should be used strictly as a planning reference and not for navigation, permitting, or other legal purposes.

Observed Presence of Alien and Invasive Algae, 2000-2013 - Hawaii

Due to the geographic isolation of the Hawaiian Islands, close to 25% of Hawaii's reef fishes and red algae species are endemic. This leaves Hawaiian coral reefs particularly vulnerable to alien invasions due to their valuable role as a biodiversity resource. Invasive algae can pose a serious threat to coral reefs by spreading and growing rapidly, smothering or outcompeting corals and other organisms. This can significantly alter the structure and function of the reef ecosystem. Four species of alien red algae have become invasive in Hawaii: prickly seaweed (Acanthophora spicifera), hookweed (Hypnea musciformis), smothering seaweed (Kappaphycus spp.), and gorilla ogo (Gracilaria salicornia). This raster data layer represents the presence of alien and invasive algal species within 1 km of an observation. Invasive algae data originated from monitoring surveys in the University of Hawaii at Manoa (UH) Fisheries Ecology Research Laboratory (FERL) Hawaii Fish and Benthic Biological Synthesis Database (2000-2013), which is synthesized from NOAA, State of Hawaii Division of Aquatic Resources (DAR), Coral Reef Assessment and Monitoring Program (CRAMP), and The Nature Conservancy (TNC), as well as invasive algae surveys conducted across the state in 2002 by Dr. Jennifer Smith (Smith et al., 2002).

These data should be considered presence only. Areas with no presence may be due to lack of survey data, surveys that did not identify algae to the species level, or observed absence. Point data for transects with observed presence of any invasive algae were assigned a value of 1 and converted to raster with 500-m pixel size. To account for uncertainty in geographic position and the fragmentation and spread of algae, the Ocean Tipping Points (OTP) project estimated presence within a 1-km radius of observed invasive algae presence. A Focal Statistics tool was run to calculate the maximum value within a 1-km radius of each pixel with the assumption that if an invasive algae was observed in one location it is likely present in at least the surrounding 1 km of reef area. Final raster values of 1 represent areas within 1 km of positive invasive algae observations while values of 0 represent the remaining area. The geographic extent of the data layer is from the shoreline of the Main Hawaiian Islands extending 5 km offshore and 1 km inshore.

Species Distribution: Bottlenose Dolphin - Hawaii

This dataset contains a collection of known point locations of bottlenose dolphins identified either via automated satellite tracking of tagged organisms or through direct human observation via shipborne and aerial surveys. This can be useful for assessing species abundance, population structure, habitat use, and behavior. This collection is aggregated from multiple data sources and survey periods listed below. Each data point contains attributes for further information about the time and source of the observation. This dataset was compiled by the Pacific Islands Ocean Observing System (PacIOOS) and may be updated in the future if additional data sources are acquired.

Cascadia Research Collective (CRC) has been undertaking surveys for odontocetes in Hawaiian waters since 2000. There are multiple island-associated populations of bottlenose dolphins recognized in Hawaiian waters, based on photo-identification, genetics, and satellite tagging, with individuals remaining associated with one or a couple of islands. Satellite tagging has been undertaken off Kauai to examine movements of individuals in relation to the U.S. Navy's Pacific Missile Range Facility. In addition, Dr. Joseph Mobley of the Marine Mammal Research Consultants (MMRC) led aerial surveys for cetaceans in Hawaiian waters from 1993-2003.

Papahanaumokuakea Marine National Monument (PMNM) - Northwestern Hawaiian Islands (NWHI)

Boundary of the Papahanaumokuakea Marine National Monument (PMNM), located in the Northwestern Hawaiian Islands (NWHI). Created in 2006, Papahanaumokuakea is the largest conservation area in the U.S. and one of the largest marine conservation areas in the world. It is home to extensive coral reefs harboring over 7,000 marine species, one quarter of which are found only in Hawaii. Many of the islands and shallow water environments are important habitats for rare species such as the threatened green sea turtle and the endangered Hawaiian monk seal. Significant cultural Native Hawaiian sites can also be found on the islands of Nihoa and Mokumanamana (Necker Island). Co-managed with the State of Hawaii and the U.S. Department of the Interior, the monument preserves one of the most untouched areas of coral reef in the world.

This layer shows the PMNM boundary after its expansion in 2016. On August 26, 2016, President Obama signed a proclamation expanding the monument from 139,797 square miles (362,073 square kilometers) to 582,578 square miles (1,508,870 square kilometers). This extended the monument boundary westward of -163 degrees longitude out to Hawaii's Exclusive Economic Zone (EEZ) at 200 nautical miles offshore. The present layer shows the monument boundary as it existed *after* this expansion. To view the previous, smaller boundary, access the data layer for "hi_noaa_nwhi_papahanaumokuakea_2006" instead.

NOTE: This layer is provided as polygon features. For polyline features, please see the layer named "hi_noaa_nwhi_papahanaumokuakea_line" instead. Both polygon and polyline formats are provided for this dataset because the monument boundary spans the antimeridian (+/-180 degrees longitude) making it difficult to display in many GIS software applications without showing a division at the antimeridian.

Sea Level Rise Inundation: 1-ft Scenario: Honolulu, Hawaii

This map shows coastal flooding around Honolulu, Hawaii due to 1 foot (0.305 m) of sea level rise. This scenario was derived using a National Geospatial Agency (NGA)-provided digital elevation model (DEM) based on LiDAR data of the Honolulu area collected in 2009. This "bare earth" DEM (vegetation and structures removed) was used to represent the current topography of the study area above zero elevation for the urban corridor stretching from Honolulu International Airport to Waikiki and Diamond Head along the south shore of Oahu. The accuracy of the DEM was validated using a selection of 16 Tidal Benchmarks located within the study area. The single value tidal water surface of mean higher high water (MHHW) modeled at the Honolulu tide gauge was used to represent sea level for the purposes of this study. Water levels are shown as they would appear during the highest high tides (excluding wind-driven tides).

Data produced in 2014 by Dr. Charles "Chip" Fletcher of the department of Geology & Geophysics (G&G) in the School of Ocean and Earth Science and Technology (SOEST) of the University of Hawaii at Manoa. Supported in part by the NOAA Coastal Storms Program (CSP) and the University of Hawaii Sea Grant College Program. These data do not consider future changes in coastal geomorphology and natural processes such as erosion, subsidence, or future construction. These data do not specify timing of inundation depths and are not appropriate for conducting detailed spatial analysis. The entire risk associated with the results and performance of these data is assumed by the user. These data should be used strictly as a planning reference and not for navigation, permitting, or other legal purposes.

Predicted Coral Cover of Porites lobata in the Hawaiian Islands

Output from a model to predict the benthic cover of Porites lobata in the Hawaiian Islands as a proportion (0-1.0). Coral cover was modeled with boosted regression trees (BRT) in R software using data from coral cover surveys and environmental covariates derived from models and/or observations including wave height, benthic geomorphology, and downwelled irradiance. The best performing BRT model was used to predict P. lobata cover for the entire geographic study domain. Data and model output represent conditions for shallow coral reefs in the Hawaiian Islands from 0 m to -30 m depth over the time period 2000-2009. Further details on methodology and results are contained in Franklin et al. (2013).

Hawaiian Ko'a Card Coral Health Assessments

The Hawaiian Ko'a Card (Coral Card) was developed by the Coral Reef Ecology Lab of the Hawaii Institute of Marine Biology (HIMB) at the University of Hawaii at Manoa to record changes in coral color of Hawaiian corals and provide a tool for people to monitor coral color as an indicator of coral health. The Ko'a Card was designed for use by everyone, including the community, citizen scientists, researchers, students, resource managers, recreational users, and visitors alike. Coral color health scores are based on actual colors of bleached and healthy Hawaiian corals. Each color sector corresponds to the density and performance of the symbiotic algae living in the coral tissue, which is linked to coral health. The lightest and darkest scores are recorded to allow for natural color variation across the coral.

Chlorophyll-a Average Annual Frequency of Anomalies, 2002-2013 - Hawaii

Chlorophyll-a is a widely used proxy for phytoplankton biomass and an indicator for changes in phytoplankton production. As an essential source of energy in the marine environment, the extent and availability of phytoplankton biomass can be highly influential for fisheries production and dictate trophic structure in marine ecosystems. Changes in phytoplankton biomass are predominantly effected by changes in nutrient availability, through either natural (e.g., turbulent ocean mixing) or anthropogenic (e.g., agricultural runoff) processes. This layer represents the annual average number of anomalies of chlorophyll-a (mg/m3) from 2002-2013, with values presented as fraction of a year. Monthly and 8-day 4-km (0.0417-degree) spatial resolution data were obtained from the MODIS (Moderate-resolution Imaging Spectroradiometer) Aqua satellite instrument from the NASA OceanColor website (http://oceancolor.gsfc.nasa.gov).

The chlorophyll-a average annual frequency of anomalies was calculated by taking the average number of times that the 8-day time series exceeded the maximum monthly climatological chlorophyll-a value from 2002-2013 for each pixel. A quality control mask was applied to remove spurious data associated with shallow water, following Gove et al., 2013. Monthly climatologies were calculated from monthly time series using only full years over the Ocean Tipping Points (OTP) project time frame of interest (2002-2013). Time series of anomalies were calculated by quantifying the number and magnitude of events from the 8-day time series that exceed the maximum climatological monthly mean. Nearshore map pixels with no data were filled with values from the nearest neighboring valid offshore pixel by using a grid of points and the Near Analysis tool in ArcGIS then converting points to raster.

Antimeridian

The Antimeridian is the +/-180 degree line of longitude, exactly opposite the Prime Meridian. It is often used as the basis for the International Date Line (IDL) because it passes through the open waters of the Pacific Ocean. However, this is a simplification of the actual IDL, which curtails several countries.
