Inheritance of the Northwestern Hawaiian Islands
The Hawaiian Islands are the end of the days when the summer is over. In fact, the range of islands stretches another thousand kilometres to the north-west, to a series of small islands, avocets and hardly sunk islets. Part of the arcipelago is an important link to the culture and nature of the most important Hawaiian islands.
This exhibition shows souvenirs from the "Golden Age of Aviation", when Midway was an important stop on trans-Pacific flights. The legacy of the northwestern Hawaiian islands will also tell the history of the Battle of Midway, the turning point in the Pacific Theater in the 2nd century BC. The exhibition also shows the working ecosystems and the spiritually important role of Papah?naumoku?kea, a paradigm for the recovery and revitalisation of singular nature and cultivated landscape.
The Naval National Memorial, founded in 2006, is one of the biggest protected areas in the whole wide area. Its seclusion provides further preservation for land and sea environments, threatened and threatened wildlife, holy Hawaiian heritage and historical ships. It is jointly administered by three co-trustees and seven co-managers who are committed to the preservation and preservation of these valuable physical and historical assets.
The exhibition "Heritage of the Northwestern Hawaiian Islands" allows the visitor to explore the islands' pristine nature and abundant past with multi-media displays and engaging exercises, which include an animated multi-media chart, a Battle of Midway simulation game, a real life-size Hawaiian Monks Scuba Diving Tour, and a real-world Hawaiian Monks Sculpture, plus a dozen rare items from our culture and nature historical collection.
Sea Level Increase and Tsunami Vulnerability of the Habitat and Wildlife of the Northwestern Hawaiian Islands
Poorly located Pacific islands are susceptible to floods caused by sea-level rises and abrupt inundations. Most of the low-lying islands of the Northwestern Hawaiian Islands (NWHI), which stretch 1,930 km beyond Hawaii's major islands, are part of the Papah?naumoku?kea Marine National Monument. NWHI supports the world's biggest marine colony, providing habitats for 22 marine birds, 4 native terrestrial birds and important feeding, hatchery and migration areas for other game.
Highresolution topographical information has been incorporated with sea-level rising simulations, wavescapes, habitats and wilderness images to better understanding the susceptibility of islands and marine life to floods and to responding to the need for management to adjust forward-looking conservation policies to take account of possible habitats and floods.

Scientists are predicting that the rising ocean levels could flood the coast and Pacific islands. The islands in northwestern Hawaii, known as Papah?naumoku?kea Marine National Monument, are home to the biggest collection of marine tropics in the hemisphere, with >15 million bird populations (22 bird species) and 4 vulnerable landfowl only found in the monument.
Present modelling of predicted changes in land and water habitats varies widely between islands, but even a slight rise in ocean levels can lead to the disappearance of sensitive habitats and an increased threat of extinction of low altitude birdlife. The present protection policies to tackle climatic changes are primarily built on interlinked lanes and reserva.
This strategy may be insufficient for many types of islands which are completely prevented from moving their geographical range by human, biologic or geographical obstacles, such as land degradation, urbanisation, imported carnivores (which do not live on the isolated, low-lying islands) or behavioural restrictions on their spread. As they identify both the areas and those susceptible to sea-level rises and abrupt floods, resources manager can schedule landscapes and reduction scenes such as restoration, new colonies of seabirds or the deliberate transportation of specimens to avoid biodiversity decline (e.g. "assisted migration" or translocation).
Papah?naumoku?kea Naval National Monument, administered by the National Oceanic and Atmospheric Administration, Department of Interior, Office of Hawaiian Affairs and the State of Hawaii, is designed to preserve the environmental health of the U.S. Northwestern Hawaiian Islands (NWHI) maritime and land based eco-systems. The high density of the small islands in the necklace and more than 95% of the world's populations are nesting on the low-lying islands of the monuments Laysan (Phoebastria immutabilis) and Schwarzfußalbatrosse (P. nigripes).
Among the threatened terrestrial endemics with 100% of their worldwide populations in the NWHI are the Laysan deer ( "Anas laysanensis"), the Laysan ringed dragonfly (Telespiza cantans), the Nihoa Miller Bird (Acrocephalus Familiis Kingi) and the Nihoa Bunting (T. ultima). While the extent of the effects of the projected increase in ocean levels and rapid change in climatic conditions on marine fowl and terrestrial threatened deep frozen plains varies from islands to islands, the risk of flooding, habitats being lost and new disease is high.
The aim of this work is to alleviate insecurity for landmasters by using rising water levels, wave-driven tides and vulnerabilities, proliferation and profusion of wild animals to deliver the information needed for multidimensional decision-making in this region in the face of climatic channlge. With the help of distant vision and geodata, we assessed the terrain, the classed flora, the modelled elevation of the ocean floor (SLR) and the vulnerabilities of avifauna.
Based on the high-resolution aerial photo of the year 2010/11 (Root Mean-Squared Errors = 0.05-0.18 m) we estimate the max. height of 20 single islands from the Kure Atoll to the French frigate SHOOSALS (range: 1.8-39.7 m) and calculated the mean height (1.7 me, standart variance 1.1 m) over all low-lying islands.
In our SLR model (without wave-driven effect, degradation and accretion), approximately 4 per cent of the entire NWHI surface area is missing with a scenario of +1. 0 metres from SLR and 26 per cent with +2. 0 metres from SLR. There are some that are particularly susceptible to reflex cameras.
In the Pearl and Hermes Atoll, for example, our analyses revealed significant loss of habitats, with 43% of the total area flooded by +1. Seven islands above the NWHI are flooded with +2. 0 metres of SLR. Restricted areas of distribution of some species of tropic bird make them particularly susceptible to the effects of NWHI climatic changes.
Climatic and SLR impact assessments underline the need for early adaption to climatic changes and reduction plans, especially for those types with finite distribution and/or areas mainly confined to the low NWHIs, such as for example: imutabilis ), Bonin Petrel (Pterodroma hypoleuca), Grey-backed Ternary ( "Onychoprion lunatus"), Laysanente (Anas laysanensis), Laysanfink (Telespiza cantans) and Hawaiian Black Seal (Monachus schauinslandi).
In addition, SLRs, which assess the impact of waves dynamic and ground water increase, may indicate increased susceptibility to climate-related habitats losses on low-lying islands.
