Firth Of Tay (Antarctica)
Firth of Tay () is a sound or firth, long and wide, extending in a northwest–southeast direction between the northeast side of Dundee Island and the east portion of Joinville Island. It merges to the northwest with Active Sound with which it completes the separation of Dundee and Joinville Islands. It was discovered in 1892–93 by Captain Thomas Robertson of the Dundee whaling expedition and named by him after the Firth of Tay of Scotland. See also *Active Reef *Tay Head Tay Head () is a rocky headland east of Mount Alexander, extending into the Firth of Tay on the south coast of Joinville Island.

Sound (geography)
In geography, a sound is a smaller body of water typically connected to a larger sea or ocean. There is little consistency in the use of "sound" in English-language place names. It can refer to an inlet, deeper than a bight and wider than a fjord, or a narrow sea or ocean channel between two bodies of land (similar to a strait), or it can refer to the lagoon located between a barrier island and the mainland. Overview A sound is often formed by the seas flooding a river valley. This produces a long inlet where the sloping valley hillsides descend to sea-level and continue beneath the water to form a sloping sea floor. The Marlborough Sounds in New Zealand are good examples of this type of formation. Sometimes a sound is produced by a glacier carving out a valley on a coast then receding, or the sea invading a glacier valley. The glacier produces a sound that often has steep, near vertical sides that extend deep underwater. The sea floor is often flat and deeper at ...

Firth
Firth is a word in the English and Scots languages used to denote various coastal waters in the United Kingdom, predominantly within Scotland. In the Northern Isles, it more usually refers to a smaller inlet. It is linguistically cognate to ''fjord'' (both from Proto-Germanic *''ferþuz''), which has a more constrained sense in English. Bodies of water named "firths" tend to be more common on the Scottish east coast, or in the southwest of the country, although the Firth of Clyde is an exception to this. The Highland coast contains numerous estuaries, straits, and inlets of a similar kind, but not called "firth" (e.g. the Minch and Loch Torridon); instead, these are often called sea lochs. Before about 1850, the spelling "Frith" was more common. A firth is generally the result of ice age glaciation and is very often associated with a large river, where erosion caused by the tidal effects of incoming sea water passing upriver has widened the riverbed into an estuary.

Dundee Island
Dundee Island is an ice-covered island lying east of the northeastern tip of Antarctic Peninsula and south of Joinville Island. It is named after the city of Dundee in Scotland. The Petrel Base is a scientific station in Antarctica belonging to Argentina. Its coordinates are 63 ° 28′S 56 ° 17′W and it is located on rocks at 18 meters above sea level at the foot of the Rosamaría glacier in the Petrel bay, the low point of Cape Welchness on Dundee Island in the Joinville archipelago. A 10-year plan began in 2013 to convert it into a permanent base. The base infrastructure has 3600 m² under roof, a 1200 m² logistics area and 25 beds. Account for transport: 2 Zodiac with outboard motor and 1 all-terrain truck of 1.5 ton. It is from this island that the American businessman Lincoln Ellsworth, accompanied by the pilot Herbert Hollick-Kenyon, took off on the 23 November 1935 for the first crossing of the Antarctic by plane.

Joinville Island
Joinville Island is the largest island of the Joinville Island group, about long in an east-west direction and wide, lying off the northeastern tip of the Antarctic Peninsula, from which it is separated by the Antarctic Sound. Joinville Island was discovered and charted roughly during 1838 by a French expedition commanded by Captain Jules Dumont d'Urville, who named it for Prince François, Prince of Joinville (1818–1900), the third son of Louis-Philippe, Duke of Orléans. It is within the Argentine, British and Chilean Antarctic claims. Geography Joinville Island consists of a series of valleys and bays, including Suspiros Bay and Balaena Valley.

Whaling
Whaling is the process of hunting of whales for their usable products such as meat and blubber, which can be turned into a type of oil that became increasingly important in the Industrial Revolution. It was practiced as an organized industry as early as 875 AD. By the 16th century, it had risen to be the principal industry in the Basque coastal regions of Spain and France. The industry spread throughout the world, and became increasingly profitable in terms of trade and resources. Some regions of the world's oceans, along the animals' migration routes, had a particularly dense whale population, and became the targets for large concentrations of whaling ships, and the industry continued to grow well into the 20th century. The depletion of some whale species to near extinction led to the banning of whaling in many countries by 1969, and to an international cessation of whaling as an industry in the late 1980s. The earliest known forms of whaling date to at least 3000 BC. Coas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firth Of Tay
The Firth of Tay (; gd, Linne Tatha) is a firth on the east coast of Scotland, into which the River Tay (Scotland's largest river in terms of flow) empties. The firth is surrounded by four council areas: Fife, Perth and Kinross, City of Dundee, and Angus. Its maximum width (at Invergowrie) is . Two bridges span the firth: the Tay Road Bridge and the Tay Rail Bridge. The marshy Mugdrum Island is the only major island in the firth. The Firth of Tay in Antarctica was discovered in 1892–93 by Captain Thomas Robertson of the Dundee whaling expedition and named by him after the one in Scotland. He also named nearby Dundee Island in honour of the main city on the firth. Natural heritage The Firth of Tay and the Eden Estuary (which lies to the south of the firth) were designated as Special Protection Areas on 2 February 2000, as Ramsar wetlands a few months later (on 28 July 2000), and as Special Areas of Conservation five years later (on 17 March 2005).

Scotland (, ) is a Countries of the United Kingdom, country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a Anglo-Scottish border, border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 Islands of Scotland, islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 Subdivisions of Scotland, administrative subdivisions or local authorities, known as council areas. Glasgow, Glasgow City is the largest council area in terms of population, with Highland (council area), Highland being the largest in terms of area. Limi ...

Active Reef
Active Reef is an isolated reef lying in the Firth of Tay, just off the north coast of Dundee Island. Discovered and named by Thomas Robertson, master of the ''Active'', one of the ships of the Dundee whaling expedition The Dundee Whaling Expedition (1892–1893) was a commercial voyage from Scotland to Antarctica. Whaling in the Arctic was in decline from overfishing. The merchants of Dundee decided to equip a fleet to sail all the way to the Weddell Sea in ... of 1892–93. The ''Active'' ran onto this reef during a gale on January 10, 1893, and lay there for 6 hours before she could be gotten off.

Sounds Of Graham Land
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequency, frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges. Acoustics Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an ''acoustician'', while someone working in the field of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
