USS Sargo (SSN-583)
USS ''Sargo'' (SSN-583), a nuclear-powered submarine, was the second ship of the United States Navy to be named for the sargo, a food and game fish of the porgy family, inhabiting coastal waters of the southern United States. Construction and commissioning The contract to build ''Sargo'' was awarded to Mare Island Naval Shipyard in Vallejo, California, on 29 September 1955 and her keel was laid down on 21 February 1956. She was launched on 10 October 1957, sponsored by the wife of Rear Admiral Frank T. Watkins, and commissioned on 1 October 1958 with Commander Daniel P. Brooks in command. Operational history Prior to completion, ''Sargo'' was designated for an Arctic cruise. She received alterations to strengthen her sail before she left the building yard. Further modifications followed her 19,000-mile (35,200 km) Pacific shakedown cruise. After her arrival at her home port, Pearl Harbor, on 1 October 1959, scientific instruments were installed to assist her in ...

Sargo
The sargo or white seabream (''Diplodus sargus'') is a species of seabream native to the eastern Atlantic and western Indian Oceans. It is found from the Bay of Biscay southwards to South Africa, including Madeira and the Canary Islands, the Mediterranean and (rarely) the Black Sea. Occasionally individuals are found off the Indian Ocean coasts of South Africa, Mozambique and Madagascar, and they are very rarely found elsewhere in the Indian Ocean, such as off Oman. An active fish, they inhabit the surf zone, but they may be found down to 50 m. They consume small crustaceans, mollusks and some seaweed and coral, using their strong jaws to crush shells. Individuals can reach 45 cm, but average 22 cm. ''Diplodus sargus'' are protandrous hermaphrodites, with individuals starting out life as males, and some becoming female later on. It is commercially fished, with 3,713 t taken in 2008. Some are reared using aquacultural techniques. The catch is eaten immediately or mark ...

Commander (United States)
In the United States, commander is a military rank that is also sometimes used as a military billet title—the designation of someone who manages living quarters or a base—depending on the branch of service. It is also used as a rank or title in non-military organizations; particularly in law enforcement. As rank History The commander rank started out as "Master and Commander" in 1674 within the Royal Navy for the officer responsible for sailing a ship under the Captain and sometimes second-in-command. Sub-captain, under-captain, rector and master-commanding were also used for the same position. With the Master and Commander also serving as captain of smaller ships the Royal Navy subsumed as the third and lowest of three grades of captain given the various sizes of ships. The Continental Navy had the tri-graded captain ranks. Captain 2nd Grade, or Master Commandant, became Commander in 1838.

Arctic Basin
The Arctic Basin (also North Polar Basin) is an oceanic basin in the Arctic Ocean, consisting of two main parts separated by the Lomonosov Ridge, a mid-ocean ridge between north Greenland and the New Siberian Islands. It is bordered by the continental shelves of Eurasia and North America. * The Eurasian Basin (also Norwegian Basin) consists of the Nansen Basin (formerly: Fram Basin) and the Amundsen Basin * The Amerasia Basin consists of the Canada Basin and the Makarov Basin Exploration Fridtjof Nansen and Otto Sverdrup sailed the basin in the ''Fram'' from 1893 to 1896. Between 1922 and 1924, Roald Amundsen Roald Engelbregt Gravning Amundsen (, ; ; 16 July 1872 – ) was a Norwegian explorer of polar regions. He was a key figure of the period known as the Heroic Age of Antarctic Exploration. Born in Borge, Østfold, Norway, Amundsen bega ... followed in the '' Maud''.

Aleutian Islands
The Aleutian Islands (; ; ale, Unangam Tanangin,”Land of the Aleuts", possibly from Chukchi language, Chukchi ''aliat'', "island"), also called the Aleut Islands or Aleutic Islands and known before 1867 as the Catherine Archipelago, are a chain of 14 large volcanic islands and 55 smaller islands. Most of the Aleutian Islands belong to the U.S. state of Alaska, but some belong to the Russian Federal subjects of Russia, federal subject of Kamchatka Krai. They form part of the Aleutian Arc in the Northern Pacific Ocean, occupying a land area of 6,821 sq mi (17,666 km2) and extending about westward from the Alaska Peninsula toward the Kamchatka Peninsula in Russia, and act as a border between the Bering Sea to the north and the Pacific Ocean to the south. Crossing 180th meridian, longitude 180°, at which point east and west longitude end, the archipelago contains both the westernmost part of the United States by longitude (Amatignak Island) and the easternmost by longitude ( ...

Iceberg
An iceberg is a piece of freshwater ice more than 15 m long that has broken off a glacier or an ice shelf and is floating freely in open (salt) water. Smaller chunks of floating glacially-derived ice are called "growlers" or "bergy bits". The sinking of the ''Titanic'' in 1912 led to the formation of the International Ice Patrol in 1914. Much of an iceberg is below the surface, which led to the expression "tip of the iceberg" to illustrate a small part of a larger unseen issue. Icebergs are considered a serious maritime hazard. Icebergs vary considerably in size and shape. Icebergs that calve from glaciers in Greenland are often irregularly shaped while Antarctic ice shelves often produce large tabular (table top) icebergs. The largest iceberg in recent history (2000), named B-15, measured nearly 300 km × 40 km. The largest iceberg on record was an Antarctic tabular iceberg of over [] sighted west of Scott Island, in the South Pacific Ocean, by the USS Glacier ...

Canadian Arctic Archipelago
The Arctic Archipelago, also known as the Canadian Arctic Archipelago, is an archipelago lying to the north of the Canadian continental mainland, excluding Greenland (an autonomous territory of Denmark). Situated in the northern extremity of North America and covering about , this group of 36,563 islands, surrounded by the Arctic Ocean, comprises much of Northern Canada, predominately Nunavut and the Northwest Territories. The archipelago is showing some effects of climate change, with some computer estimates determining that melting there will contribute to the rise in sea levels by 2100. History Around 2500 BCE, the first humans, the Paleo-Eskimos, arrived in the archipelago from the Canadian mainland. Between 1000–1500 CE, they were replaced by the Thule people, who are the ancestors of today's Inuit. British claims on the islands, the British Arctic Territories, were based on the explorations in the 1570s by Martin Frobisher. Canadian sovereignty was originally (1870 ...

Hawaiian Flag
The flag of Hawaii ( Hawaiian: '), in addition to the current state design, previously had been used by the kingdom, protectorate, republic, and territory of Hawaii. It is the only U.S. state flag to include a foreign country's national flag. The inclusion of the Union Jack of the United Kingdom is a mark of the Royal Navy's historical relations with the Hawaiian Kingdom, particularly with King Kamehameha I. The flag continued to be used after the 1893 overthrow of the Hawaiian Kingdom. Background In 1793, Captain George Vancouver, of the British Royal Navy, having previously visited the islands in 1778–1779 with Captain James Cook, returned in command of HMS ''Discovery''. During the visit, Vancouver met with Kamehameha I and presented him with a Red Ensign, used by the Royal Navy at the time. The Kingdom of Ireland was not a formal part of the United Kingdom before 1801, which meant that, at this time, the British flag did not contain the Saint Patrick's Cross of Irel ...

North Pole
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole. The North Pole is by definition the northernmost point on the Earth, lying antipodally to the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the North Pole, so any time can be used as the local time. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere. The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about away, though some perhaps semi-permanent gravel banks lie slightly clos ...

Arctic Circle
The Arctic Circle is one of the two polar circles, and the most northerly of the five major circles of latitude as shown on maps of Earth. Its southern equivalent is the Antarctic Circle. The Arctic Circle marks the southernmost latitude at which, on the December solstice, the shortest day of the year in the northern hemisphere, the sun will not rise all day, and on the June solstice, the longest day of the year in the northern hemisphere, the sun will not set. These phenomena are referred to as polar night and midnight sun respectively, and the further north one progresses, the more pronounced these effects become. For example, in the Russian port city of Murmansk, three degrees above the Arctic Circle, the sun does not rise for 40 successive days in midwinter. The position of the Arctic Circle is not fixed and currently runs north of the Equator. Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2° over a 41,000-year period, o ...

USS Staten Island (AGB-5)
USCGC ''Staten Island'' (WAGB-278) was a United States Coast Guard . Laid down on 9 June 1942 and launched on 28 December 1942, the ship was commissioned on 26 February 1944, and almost immediately afterward transferred to the Soviet Union, under the Lend Lease program, under the name ''Severny Veter'', which loosely translates as ''Northwind'', until 19 December 1951. When returned to the United States Navy, she was designated USS ''Northwind'' until 15 April 1952, when she was renamed ''Staten Island'' to distinguish her from her successor which had been laid down shortly after she was lent to the Soviet Union. The ship was transferred to the U.S. Coast Guard as USCGC ''Staten Island'' in February 1965, and served until November 1974, before being scrapped. Construction ''Staten Island'' was one of the icebreakers designed by Lieutenant commander Edward Thiele and Gibbs & Cox of New York, who modeled them after plans for European icebreakers he obtained before the start of Worl ...
