November 2011 Bering Sea Cyclone
The November 2011 Bering Sea cyclone was one of the most powerful extratropical cyclones to affect Alaska on record. On November 8, the National Weather Service (NWS) began issuing severe weather warnings, saying that this was a near-record (or record) storm in the Bering Sea. It rapidly deepened from to in just 24 hours before bottoming out at 943 mbar (hPa; 27.85 inHg), roughly comparable to a Category 3 or 4 hurricane. The storm had been deemed life-threatening by many people. The storm had a forward speed of at least before it had reached Alaska. The storm began affecting Alaska in the late hours of November 8, 2011. The highest gust recorded was on Little Diomede Island. One person was reported missing after being swept into the Bering Sea, and he was later pronounced dead. Meteorological synopsis In early November 2011, an extratropical cyclone developed over the western Pacific Ocean. Gradually intensifying, the system moved rapidly northeastward at and ...

Little Diomede Island
Little Diomede Island or Yesterday Island (, formerly known as Krusenstern Island, ) is an inhabited island of Alaska. It is the smaller of the two Diomede Islands located in the Bering Strait between the Alaskan mainland and Siberia. The island has one town, also called Diomede. Etymology The Diomede Islands are named after Saint Diomedes. The Inupiaq name means "the other one" or "the one over there". The two islands are respectively nicknamed "Yesterday Island" (Little Diomede Island) and " Tomorrow Island" (Big Diomede Island) because the International Date Line runs between them, making the date on Little Diomede Island always one day behind the date on Big Diomede Island. Geography Little Diomede Island is located about west of mainland Alaska, in the middle of the Bering Strait. It is only from the International Date Line and about from the Russian island of Big Diomede. According to the United States Census Bureau, the island has a total area of , all of it land. ...

Beaufort Scale
The Beaufort scale ( ) is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale. It was devised in 1805 by Francis Beaufort a hydrographer in the Royal Navy. It was officially adopted by the Royal Navy and later spread internationally. History The scale that carries Beaufort's name had a long and complex evolution from the previous work of others (including Daniel Defoe the century before). In the 18th century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective — one man's "stiff breeze" might be another's "soft breeze"—: Beaufort succeeded in standardising a scale.reprinted in 2003 by Dover Publications./ref> The scale was devised in 1805 by Francis Beaufort (later Rear Admiral), a hydrographer and a Royal Navy officer, while serving on , and refined until he was Hydrographer of the Navy in the 1830s, when it was ado ...

Seawall
A seawall (or sea wall) is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation, and leisure activities from the action of tides, waves, or tsunamis. As a seawall is a static feature, it will conflict with the dynamic nature of the coast and impede the exchange of sediment between land and sea. Seawall designs factor in local climate, coastal position, wave regime (determined by wave characteristics and effectors), and value (morphological characteristics) of landform. Seawalls are hard engineering shore-based structures that protect the coast from erosion. Various environmental issues may arise from the construction of a seawall, including the disruption of sediment movement and transport patterns. Combined with a high construction cost, this has led to increasing use of other soft engineering coastal management ...

Storm Surge
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. The main meteorological factor contributing to a storm surge is high-speed wind pushing water towards the coast over a long fetch. Other factors affecting storm surge severity include the shallowness and orientation of the water body in the storm path, the timing of tides, and the atmospheric pressure drop due to the storm. As extreme weather becomes more intense and the sea level rises due to climate change, storm surges are expected to cause more risk to coastal populations. Communities and governments can adapt by building hard infrastructure, like surge barriers, soft infrastructure, like coastal dunes or mangroves, improving coastal construction practices and building social strat ...

Coastal Flooding
Coastal flooding occurs when dry and low-lying land is submerged (flooded) by seawater. The range of a coastal Flood, flooding is a result of the elevation of floodwater that penetrates the inland which is controlled by the topography of the coastal land exposed to flooding. The seawater can flood the land via several different paths: direct flooding, overtopping or breaching of a barrier. Coastal flooding is largely a natural event. Due to the effects of climate change (e.g. sea level rise and an increase in extreme weather events) and an increase in the population living in coastal areas, the damage caused by coastal flood events has intensified and more people are being affected. Coastal plain, Coastal areas are sometimes flooded by unusually high tides, such as spring tides, especially when compounded by high winds and storm surges. This was the cause of the North Sea flood of 1953 which flooded large swathes of the Netherlands and the East coast of England. When humans modif ...

Kenai Peninsula
The Kenai Peninsula ( Dena'ina: ''Yaghenen'') is a large peninsula jutting from the coast of Southcentral Alaska. The name Kenai (, ) is derived from the word "Kenaitze" or "Kenaitze Indian Tribe", the name of the Native Athabascan Alaskan tribe, the Kahtnuht’ana Dena’ina ("People along the Kahtnu (Kenai River)"), who historically inhabited the area. They called the Kenai Peninsula ''Yaghanen'' ("the good land"). Geography The peninsula extends about southwest from the Chugach Mountains, south of Anchorage. It is separated from the mainland on the west by Cook Inlet and on the east by Prince William Sound. Most of the peninsula is part of the Kenai Peninsula Borough. Athabaskan and Alutiiq Native groups lived on the peninsula for thousands of years prior to colonization during the Russian America era. The glacier-covered Kenai Mountains run along the southeast spine of the peninsula along the coast of the Gulf of Alaska. Much of the range is within Kenai Fjords Natio ...

Wrangel Island
Wrangel Island (, ; , , ) is an island of the Chukotka Autonomous Okrug, Russia. It is the List of islands by area, 92nd-largest island in the world and roughly the size of Crete. Located in the Arctic Ocean between the Chukchi Sea and East Siberian Sea, the island lies astride the 180th meridian, 180th meridian (geography), meridian. The International Date Line is therefore displaced eastwards at this latitude to keep the island, as well as the Chukchi Peninsula on the Russian mainland, on the same day as the rest of Russia. The closest land to Wrangel Island is the tiny and rocky Herald Island (Arctic), Herald Island located to the east.Kosko, M.K., M.P. Cecile, J.C. Harrison, V.G. Ganelin, N.V., Khandoshko, and B.G.

Chukchi Sea
The Chukchi Sea (, ), sometimes referred to as the Chuuk Sea, Chukotsk Sea or the Sea of Chukotsk, is a marginal sea of the Arctic Ocean. It is bounded on the west by the Long Strait, off Wrangel Island, and in the east by Point Barrow, Alaska, beyond which lies the Beaufort Sea. The Bering Strait forms its southernmost limit and connects it to the Bering Sea and the Pacific Ocean. The principal port on the Chukchi Sea is Uelen in Russia. The International Date Line crosses the Chukchi Sea from northwest to southeast. It is displaced eastwards to avoid Wrangel Island as well as the Chukotka Autonomous Okrug on the Russian mainland. Etymology In 1928, during hydrographic observations, the Norwegian polar explorer Harald Sverdrup discovered that the sea lying between Point Barrow and Wrangel Island was very different from the sea between the New Siberian Islands and Wrangel Island and therefore should be separated from the East Siberian Sea. It was decided to call the newly ...
