Active Sound
Active Sound () is a sound, averaging wide, extending in an east-northeast direction from Antarctic Sound and joining the Firth of Tay with which it separates Joinville and Dundee Islands. Discovered in 1892–93 by Captain Thomas Robertson of the Dundee whaling expedition.

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 the ...

Antarctic Sound
The Antarctic Sound is a body of water about long and from wide, separating the Joinville Island group from the northeast end of the Antarctic Peninsula. The sound was named by the Swedish Antarctic Expedition under Otto Nordenskjöld for the expedition ship ''Antarctic'' which in 1902, under the command of Carl Anton Larsen, was the first vessel to navigate it. Since 1998 cruise ships have been visiting the area. Geography The Antarctic Sound is the stretch of water that separates Trinity Peninsula, the tip of the Antarctic Peninsula, from the Joinville Island group which consists of D'Urville Island, Joinville Island, Dundee Island and the smaller Bransfield Island. The northern limit of the sound, where it joins the Bransfield Strait, is the line connecting Cape Dubouzet (63°16'S, 57°03'W) on Trinity Peninsula with Turnbull Point (63°02'S, 56°36'W) on D'Urville Island. The southern limit is the line connecting Cape Scrymgeour on Andersson Island (63°35'S, 56°26'W) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The name, given by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1963, is derived from the Firth of ...

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.

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.

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 search of right whales. Antarctic whaling was mostly done from shore-based stations. On 6 September 1892, four steam-powered whaling ships, the , , '' Diana'' and ''Polar Star'', set off.Voyage of the Balaena Glasgow Digital Library, retrieved 3 December 2013 In the end they found no whales they could harvest as the s of the Antarctic were too powerful to be captured.

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] |
