Sunset At Ernest Sound, Alaska, Circa 1908 (AL+CA 3389)
Sunset, also known as sundown, is the daily disappearance of the Sun below the horizon due to Earth's rotation. As viewed from everywhere on Earth (except the North and South poles), the equinox Sun sets due west at the moment of both the spring and autumn equinoxes. As viewed from the Northern Hemisphere, the Sun sets to the northwest (or not at all) in the spring and summer, and to the southwest in the autumn and winter; these seasons are reversed for the Southern Hemisphere. The time of sunset is defined in astronomy as the moment when the upper limb of the Sun disappears below the horizon. Near the horizon, atmospheric refraction causes sunlight rays to be distorted to such an extent that geometrically the solar disk is already about one diameter below the horizon when a sunset is observed. Sunset is distinct from twilight, which is divided into three stages. The first one is ''civil twilight'', which begins once the Sun has disappeared below the horizon, and continues u ...

Alaska Panhandle
Southeast Alaska, colloquially referred to as the Alaska(n) Panhandle, is the southeastern portion of the U.S. state of Alaska, bordered to the east and north by the northern half of the Canadian province of British Columbia (and a small part the Yukon Territories). The majority of Southeast Alaska's area is part of the Tongass National Forest, the United States' largest national forest. In many places, the international border runs along the crest of the Boundary Ranges of the Coast Mountains (see Alaska boundary dispute). The region is noted for its scenery and mild, rainy climate. The largest cities in the region are Juneau, Sitka, and Ketchikan. This region is also home to Hyder, the easternmost town in Alaska. Geography Southeast Alaska has a land area of , comprising much of the Alexander Archipelago. The largest islands are, from North to South, Chichagof Island, Admiralty Island, Baranof Island, Kupreanof Island, Revillagigedo Island and Prince of Wales Island. Ma ...

It has a land area of , making it the 29th largest island in the United States. Wrangell is separated from the mainland by the narrow Blake Channel. The first European to sight the island was James Johnstone, one of George Vancouver’s officers during his 1791-1795 expedition, in 1793. He only charted its east coast, not realizing it was an island. It was occupied in 1834 by the Russians. It is named after Ferdinand Wrangel, a Baltic German explorer in Russian service, and government official.

Vancouver Expedition
The Vancouver Expedition (1791–1795) was a four-and-a-half-year voyage of exploration and diplomacy, commanded by Captain George Vancouver of the Royal Navy. The British expedition circumnavigated the globe and made contact with five continents. The expedition at various times included between two and four vessels, and up to 153 men, all but 6 of whom returned home safely. Origin Several previous voyages of exploration including those of Ferdinand Magellan and James Cook, and the Spanish Manila-Acapulco galleons trade route active since 1565, had established the strategic and commercial value of exploring and claiming the Pacific Ocean access, both for its wealth in whales and furs and as a trade route to the " Orient". Britain was especially interested in improving its knowledge of the Southern Pacific whale fisheries, and in particular the location of the strategically positioned Australia, New Zealand, the legendary ''Isla Grande'', and the Northwest Passage.

Ernest Augustus, King Of Hanover
Ernest Augustus (german: Ernst August; 5 June 177118 November 1851) was King of Hanover from 20 June 1837 until his death in 1851. As the fifth son of King George III of the United Kingdom and Hanover, he initially seemed unlikely to become a monarch, but none of his elder brothers had a legitimate son. When his older brother William IV, who ruled both kingdoms, died in 1837, his niece Victoria inherited the British throne under British succession law, while Ernest succeeded in Hanover under Salic law, which barred women from the succession, thus ending the personal union between Britain and Hanover that had begun in 1714. Ernest was born in London but was sent to Hanover in his adolescence for his education and military training. While serving with Hanoverian forces near Tournai against Revolutionary France, he received a disfiguring facial wound. He was created Duke of Cumberland and Teviotdale in 1799. Although his mother Queen Charlotte disapproved of his marriage in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrographic Survey
Hydrographic survey is the science of measurement and description of features which affect maritime navigation, marine construction, dredging, offshore oil exploration/ offshore oil drilling and related activities. Strong emphasis is placed on soundings, shorelines, tides, currents, seabed and submerged obstructions that relate to the previously mentioned activities. The term ''hydrography'' is used synonymously to describe ''maritime cartography'', which in the final stages of the hydrographic process uses the raw data collected through hydrographic survey into information usable by the end user. Hydrography is collected under rules which vary depending on the acceptance authority. Traditionally conducted by ships with a sounding line or echo sounding, surveys are increasingly conducted with the aid of aircraft and sophisticated electronic sensor systems in shallow waters. Organizations National and International Maritime Hydrography Hydrographic offices evolved fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straits Of Alaska
A strait is an oceanic landform connecting two seas or two other large areas of water. The surface water generally flows at the same elevation on both sides and through the strait in either direction. Most commonly, it is a narrow ocean channel that lies between two land masses. Some straits are not navigable, for example because they are either too narrow or too shallow, or because of an unnavigable reef or archipelago. Straits are also known to be loci for sediment accumulation. Usually, sand-size deposits occur on both the two opposite strait exits, forming subaqueous fans or deltas. Terminology The terms '' channel'', ''pass'', or ''passage'' can be synonymous and used interchangeably with ''strait'', although each is sometimes differentiated with varying senses. In Scotland, ''firth'' or ''Kyle'' are also sometimes used as synonyms for strait. Many straits are economically important. Straits can be important shipping routes and wars have been fought for control of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
