Delta Stream
Delta Stream () is a small meltwater stream flowing from Howard Glacier into Lake Fryxell in Taylor Valley, Victoria Land. It was first studied on the ground by Troy L. Pewe during U.S. Navy Operation Deepfreeze, 1957–58, and so named by him because the stream has a series of deltas A river delta is a landform shaped like a triangle, created by deposition of sediment that is carried by a river and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarel ... along its length which have been cut through as the stream was rejuvenated, the rejuvenation being caused by the lowering of the former glacial lake.

Howard Glacier
Howard Glacier () is a small alpine glacier just west of Crescent Glacier, flowing into Taylor Valley on the north from the Kukri Hills, in Victoria Land, Antarctica. The glacier was studied in December 1957 by U.S. geologist T.L. Pewe, who named it for Arthur D.

Lake Fryxell
Lake Fryxell is a frozen lake long, between Canada Glacier and Commonwealth Glaciers at the lower end of Taylor Valley in Victoria Land, Antarctica. It was mapped in the early 1900s and named during Operation Deep Freeze in the 1950s. There are several forms of algae living in the waters and a weather station located at the lake. Geography Lake Fryxell is deep, making it so the deepest portion of the lake is below sea level. The lake is dammed by Canada Glacier, making it so that it has no natural outflow. It is covered with about of ice, but during the summer months, the ice can clear along the shoreline. There are a few small islands as well as several shallow areas. The average annual ablation is between and , which is significantly lower when compared to other nearby frozen water bodies, such as the waters adjacent to Ross Island. Watershed The watershed contains thirteen streams flowing into the lake, forming a watershed that has an area roughly in size. Where a few of t ...

Taylor Valley
Taylor Valley is the southernmost of the three large McMurdo Dry Valleys in the Transantarctic Mountains, Victoria Land, Antarctica, located west of McMurdo Sound at approximately . The valley extends from Taylor Glacier in the west to McMurdo Sound at Explorers Cove at the northwest head of New Harbour in the east and is about long. It was once occupied by the receding Taylor Glacier, from which it derives its name. Taylor Valley contains Lake Bonney in the west (inward), and Lake Fryxell in the east (coastward), and Lake Hoare, Lake Chad, Lake Popplewell, Mummy Pond and Parera Pond close together between the two. Further east of Lake Bonney is Pearse Valley. Taylor Valley is separated from Wright Valley in the north by Asgard Range, and from Ferrar Glacier in the south by Kukri Hills. At its southernmost end, Taylor Valley becomes Quinn Gully, a mainly ice-free gully, which descends between MacDonald Hills and Hjorth Hill to Explorers Cove in New Harbour. It was named by ...

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troy L
Troy ( el, Τροία and Latin: Troia, Hittite: 𒋫𒊒𒄿𒊭 ''Truwiša'') or Ilion ( el, Ίλιον and Latin: Ilium, Hittite: 𒃾𒇻𒊭 ''Wiluša'') was an ancient city located at Hisarlik in present-day Turkey, south-west of Çanakkale and about miles east of the Aegean Sea. It is known as the setting for the Greek myth of the Trojan War. In Ancient Greek literature, Troy is portrayed as a powerful kingdom of the Heroic Age, a mythic era when monsters roamed the earth and gods interacted directly with humans. The city was said to have ruled the Troad until the Trojan War led to its complete destruction at the hands of the Greeks. The story of its destruction was one of the cornerstones of Greek mythology and literature, featuring prominently in the ''Iliad'' and the ''Odyssey'', and referenced in numerous other poems and plays. Its legacy played a large role in Greek society, with many prominent families claiming descent from those who had fought there. In the ...

River Delta
A river delta is a landform shaped like a triangle, created by deposition (geology), deposition of sediment that is carried by a river and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment. It is so named because its triangle shape resembles the Greek letter Delta. The size and shape of a delta is controlled by the balance between watershed processes that supply sediment, and receiving basin processes that redistribute, sequester, and export that sediment. The size, geometry, and location of the receiving basin also plays an important role in delta evolution. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide Coast, coastline defense and can impact drinking water supply. They are also Ecology, ecologically important, with different species' assemblages ...

Rivers Of Victoria Land
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...
